The River Wye: Technology-Driven River Stewardship

WRITTEN BY | NATASHA POSNETT

The River Wye, once celebrated for its rich biodiversity and crystal-clear waters, has sadly joined the growing list of natural landmarks impacted by human activity. Stretching through some of the most picturesque landscapes in England and Wales, the river now finds itself at the heart of an environmental crisis, with agricultural pollution playing a significant role in the decline of its water quality. However, amid this decline, a transformation is underway. The Wye is emerging as a symbol of innovation and resilience. Efforts to restore and protect the river are gaining momentum, combining technology, data and grassroots engagement in a pioneering approach to environmental management.

The Challenges

Concerns about the River Wye’s health began escalating in the early 2020s, with widespread reports of algal blooms and murky water replacing the clear flow once synonymous with the region. Investigations pointed to elevated levels of phosphorus mainly from manure runoff tied to booming poultry farms in the catchment area.

Traditional regulatory mechanisms proved too slow and disconnected to keep pace with the scale and speed of degradation. There was an urgent need for real-time insights and proactive interventions- a shift only made possible through the adoption of advanced environmental technologies.

The Solution

To combat these challenges, local authorities, environmental groups and landowners around the Wye began implementing a digital Environmental Management System (EMS). The framework could be tailored specifically to the Wye ecosystem and the work began by tracking pollution levels and supervising land use. For it to work at its best, it was essential to include all stakeholders and ensure that they were aligned on the issue and steps required to make a difference.

Technology in Action: How EMS is Changing the Game

Real time monitoring and a fast response is so important. Where once water samples were manually collected and tested in labs weeks later, sensors in the Wye now stream data 24 hours a day. A sudden drop in oxygen can immediately trigger alerts, flagging a possible sewage leak or runoff event upstream. This allows local teams to respond in hours rather than weeks, reducing ecological damage and improving accountability.

With GIS and satellite imagery, environmental teams can observe how land use shifts affect river health. This spatial intelligence enables more strategic planning, like where to install reed beds or restore wetlands to filter pollutants.

Artificial intelligence is being used to model risk scenarios, taking into account rainfall forecasts, soil moisture levels and farming schedules. For example, if heavy rain is expected after a period of fertiliser

application, the EMS can forecast a spike in phosphorus runoff, giving time to delay spreading or activate protective measures.

The Importance of Community and Policy

One of the most transformative aspects of the River Wye EMS is how it encourages community participation. Farmers receive support to improve practices, residents can log pollution sightings via citizen science apps, and conservation groups have access to shared data to guide habitat restoration projects.

Still, challenges remain. Fragmented data systems between agencies can hinder collaboration, and rural regions often struggle with funding and infrastructure needed to scale these technologies. However, national frameworks like the Environment Act 2021 and the 25-Year Environment Plan are increasingly emphasising data-led governance, aligning policy with innovation.

Drivers of Change

One of the most powerful drivers of environmental change on the Wye has been the rise of citizen science. Local organisations like Friends of the River Wye and the Wye Alliance have mobilised hundreds of volunteers who now form a network of water quality monitors across the catchment. The volunteers take regular samples from points along the river. These data points are mapped and visualised to reveal pollution hotspots and seasonal trends, and in some cases, have triggered investigations by regulatory bodies. With over 400 active contributors involved as of 2025, citizen science on the Wye has become an essential complement to official monitoring networks. It not only fills critical data gaps between formal testing stations but also fosters grassroots accountability, enabling communities to actively protect and advocate for their river.

The Environment Agency (EA) has significantly expanded its role in the River Wye catchment by investing in realtime monitoring technologies to better understand and respond to pollution events. In 2022, the EA deployed a network of multiparameter sondes and autosamplers at

key sites along the Wye. These devices continuously track water quality indicators offering a high-resolution picture of the river’s health that far surpasses traditional spotsampling methods. By combining these datasets with land use information and weather conditions, the Environment Agency is shifting from reactive regulation toward datainformed intervention, reinforcing the idea that precision monitoring is essential in managing complex ecosystems like the Wye.

A Microcosm of a National Issue

The story of the River Wye reflects a broader reality: across England, only 14% of rivers are currently classified as being in good ecological status. Agriculture, sewage overflows and climate-induced extremes are pushing ecosystems to the brink. Reactive monitoring is no longer enough.

What the Wye demonstrates is that with the right technological backbone, it’s possible to shift from crisis response to proactive stewardship. Data is collected to inform smart, timely, collective action.

The Bigger Picture: Rivers as Indicators of Change

Rivers like the Wye are more than just natural features, they’re indicators of environmental health and public will. Their condition reveals how well we’re balancing economic needs with ecological limits. And while Environmental Management Systems alone won’t solve every problem, they offer something previously out of reach: a unified, real-time view of environmental change, actionable by everyone from policymakers to local citizens.

The transformation underway in the Wye catchment is still in progress, but it sends a clear message: the future of river stewardship in the UK will be written in code as much as conservation. And that future begins with seeing rivers not only as victims of pollution, but as platforms for innovation and collaboration.

The Tech That’s Trying to Save Britain’s Beaches

WRITTEN BY | DARBY BONNER

Last month, as I stood at the top of a Cornish clifftop looking down to the waters below, I saw our familiar coastline through new eyes. While some beaches remained beautifully pristine, others told a more concerning story. I observed a decline in marine life, waters that were less clear than they should be, and in some areas, visible oil residue on the surface. These observations opened my eyes to the challenges facing our coastal waters and highlighted the urgent need for closer, continuous water quality monitoring. It suddenly hit me that Cornwall wasn’t disappointing me, but it was revealing important truths that demanded attention and action.

The statistics are sobering. This year (2025), Porthluney Beach in Cornwall was named as the worst beach in Britain after being given the Environment Agency’s poorest water quality rating. The list is long and troubling: Blackpool North, Weston-super-Mare, and many others across Lancashire, Kent, Devon, and Dorset – all beaches that have received multiple ‘Brown Flags’ for poor water quality.

But instead of disregarding these popular coastlines, British scientists and innovators are creating some extraordinary water tech that could completely change how we manage and police our coastal waters across the UK.

The 15-Minute Revolution

BactiQuick is a world first and revolutionising water testing and safety, developed by Cornwallbased biosensor specialist Molendotech in partnership with the University of Plymouth in May 2025. This pocket-sized device represents a quantum leap in water quality testing, measuring a wide range of endotoxins, including E.coli and Salmonella, and delivering results in just 15 minutes compared to the traditional 48-hour wait.

The breakthrough lies in its potential for widespread application. Imagine if this rapid-testing technology used by lifeguards, beachgoers, and local communities could be scaled up and integrated into our national monitoring systems. Instead of waiting days for laboratory results, coastal authorities, environmental agencies, and community groups could have real-time data to make immediate decisions about public safety and pollution response.

When the device was tested at Perranporth, the results were eye-opening. Despite its crystal-clear appearance, the stream flowing onto the popular family beach flashed red, signalling a high risk. Meanwhile, the seemingly murky Truro River, which flows into the River Fal, surprisingly showed green, proving that appearances can be dangerously deceptive.

AI Joins the Fight

The University of Plymouth is pushing boundaries even further with artificial intelligence. Their Vis4Sea project has

installed innovative HydraSpectra sensors on the Tamar Bridge, using fibre optics to detect water colour changes that indicate pollution from fertilisers, sewage, and heavy metals. This low-tech, carbon-zero solution provides real-time monitoring of river pollution as it flows toward Plymouth Sound.

Meanwhile, the Environment Agency is trialling AIpowered citizen science initiatives at beaches like Par Sands. QR codes prompt beachgoers to share observations about water clarity, pollution signs, and beach conditions through the Hello Lamp Post platform, creating a crowd-sourced early warning system.

The Bigger Picture

The BactiQuick initiative, funded by £380,000 from Innovate UK, represents a blueprint for the future of water quality management. Rather than focusing on individual testing, the vision encompasses a comprehensive early warning system that combines rapid bacterial analysis with weather data and smartphone technology. This could enable water companies, environmental agencies, and coastal communities to identify not just where pollution is occurring, but also predict when and where it poses the most significant risk.

The principles behind this technology (rapid detection, real-time data, and community engagement) could transform our entire approach to coastal management. Imagine a national network of monitoring stations using similar rapid-testing methods, feeding data into a centralised system that provides live updates on water quality across the UK’s 451 designated bathing waters.

Professor Simon Jackson, Molendotech’s founder, captures the broader vision: “With increased public river use, there is growing demand for evidence that the water

is safe at any given time. This technology provides communities with the tools to become data providers and have greater confidence in their local water quality [1].”

Securing Our Coast for People and Planet

These innovations point toward a transformation in how we protect our coastal environment. The integration of rapid testing, AI monitoring, and citizen science creates a robust model that could be replicated across the UK and beyond. What we’re seeing in Cornwall and Plymouth today could become the standard for coastal management everywhere.

The key lies in recognising that water quality isn’t just an environmental issue, it’s a public health, economic, and social priority that demands innovative solutions. As climate change intensifies weather patterns and puts increasing pressure on our infrastructure, technologies like these offer hope for maintaining safe, enjoyable coastal access while protecting marine ecosystems. While traditional monitoring tells us yesterday’s story, these technologies provide today’s reality. As climate change intensifies rainfall patterns and ageing infrastructure struggles to cope, such innovations are necessary.

My enlightening trip to Cornwall reminded me that we can’t take water quality for granted. Still, it also revealed something profoundly hopeful - British innovation is rising to meet our coastal challenges head-on. From AIpowered monitoring systems to rapid bacterial detection, technology is opening up environmental knowledge and empowering communities to take action. The blue waters we cherish aren’t just for making memories; they’re a future we can work toward for future generations to enjoy and for marine life to thrive. And with these groundbreaking tools showing us the way forward, that future feels achievable to me.

Improving Water Quality in Benin: The Decentralised Approach

Written By | MARTYN SHUTTLEWORTH

In many regions, improving water quality is complex due to the many interlinked causes that require several solutions combined into a coherent whole. Programs to provide cleaner water may seek to reduce the amount of pollution entering water sources while also improving treatment, upgrading infrastructure, and providing filters for households. Failing to include any of these steps can see the entire program lose its impact.

Such multilayered approaches usually encompass several government departments and international donors, so the process risks becoming fragmented with resources wasted. Governments need to develop intuitive plans that tackle every aspect of improving water quality, while supporting collaboration and focusing efforts where they will be most effective.

Benin

The West African country of Benin, with a population of about 14 million people, is one nation that implemented a largely successful water quality improvement over the past few decades. The republic faces the same struggles with pollution, sanitation, and water quality as many other countries in the region. However, since 1990, governments have followed clear plans for improving water quality, especially in rural areas. Benin showed how governments can bring together international donors, government, and local communities to improve access to clean water across the entire country.

The Decentralized Approach

The key to improving Benin’s water quality lay in a decentralised approach that devolved many powers and decisions to municipalities, especially in rural areas. They understood the needs of their communities and were more responsive and accountable than someone in a faraway city. The decentralisation also made sure that NGOs and other organisations could work directly with communities without additional layers of bureaucracy and wasted time. To support the process, in 2007, the government created a national water utility, SONEB, to bring groups together and oversee progress in urban areas. An organisation called the Direction Générale de l’Eau performs the same role in rural Benin.

In the subsequent decades, this process proved largely successful and Benin achieved its 2015 Millennium Development Goal for access to drinking water, especially in rural areas where average water supply coverage rose from 42% to 73% by 2022. The government and NGOs have invested heavily in sanitation, boreholes, and water treatment, improving the situation immeasurably, but a significant proportion of the population still needs cleaner water.

Despite the great progress and solid foundations, a number of challenges remain, especially in rural areas where rivers, lakes, and wells can be contaminated, while supplies from private sellers can be of questionable

Martyn Shuttleworth Staff Writer at H2O Global News

quality. Wastewater treatment needs to be improved and infrastructure in cities is sometimes poorly maintained, while agricultural and industrial runoff still cause problems. With continued investment and improvements needed, the government and its partners are developing a raft of new policies.

Developing New Policies

In line with its Sustainable Development Goals and drive to ensure 100% of the population can access safe water by 2026, Benin’s government understands that meeting its targets for water quality helps it reach development goals covering other areas. For example, better quality water supports health, through reduced disease, and the environment through cleaner rivers and reduced pollution.

As suggested by Aqua Maya, some of the government’s ongoing policies related to water quality include:

• Rural Water Supply: Improve access to clean water, especially in remote areas, by drilling more locallymanaged boreholes.

• Community/Household Solutions: Small water treatment plants for river water, portable filtration, and chlorination systems will provide cleaner water in homes and communities.

• Training: Local communities receive training in how to manage, maintain, and repair their new boreholes and treatment facilities.

• Urban Water Supplies: While urban areas show better average water quality than rural areas, there is still room for improvement. Ongoing projects will repair and upgrade distribution systems, expand access, and invest in improved sanitation infrastructure to reduce water pollution.

• Monitoring and Treatment: The government intends to invest in better, more frequent water quality monitoring to highlight where there are problems, while investing in additional water treatment capacity.

• Regulations: Because private water sellers are crucial for supplying clean water in many areas, the government plans to introduce stricter standards for bottled water and improve enforcement.

• Private Public Partnerships: To encourage the high levels of investment often needed in the water sector, Benin is encouraging Private Public Partnerships to support new projects and bring additional expertise.

All of these programs include input from NGOs such as UNICEF and the World Bank but, importantly, they are community driven and bring a sense of ownership. For example, Benin’s younger generations are increasing the awareness of water quality and teaching the importance of preventing pollution from tainting water sources.

Building for the Future

Through its shrewd policy of decentralization and focus on community-based approaches, Benin has seen significant progress in improving water quality. Despite this, challenges remain, especially in rural areas, and population growth and climate change could exacerbate the problems.

By building upon previous good progress and continuing to work with international partners, the government can allocate resources where they are needed. Benin can continue to focus on improving water infrastructure and resources while incorporating new technology to help it continue to improve water quality.

COVER FEATURE

Dr. Tasrina Choudhury's Journey in Water Quality Technology & Environmental Science

INTERVIEWED BY | DARBY BONNER

We spoke to Dr. Tasrina Choudhury, our cover feature this month, about her remarkable journey in environmental science. Growing up in Bangladesh, where rivers and coastal ecosystems are central to life, she witnessed firsthand how pollution and industrialisation were degrading these vital water systems. This curiosity turned into concern as she learned about invisible threats in water systems and their impacts on ecosystems and human health.

After completing her education in Applied Chemistry and Chemical Engineering from the University of Dhaka, she joined the Bangladesh Atomic Energy Commission as a scientist. Her work is driven by the belief that clean water is a fundamental right, and science can provide the tools to protect it for future generations.

How have your international experiences shaped your research approach?

I have participated in many international trainings and workshops across Europe, Asia, and the Pacific, strengthening my expertise in nuclear and isotopic techniques, environmental monitoring, water quality analysis, and laboratory quality assurance. From advanced

Dr. TASRINA RABIA CHOUDHURY SCIENTIST, BANGLADESH

instrumentation training in France to marine ecosystem workshops in Monaco, isotope hydrology workshop in New Zealand, and capacity-building programs in China, Australia, and Slovenia, my global experiences have shaped my research approach and leadership in water quality technology and environmental science.

What do your studies reveal about contamination in Bangladesh’s coastal waters?

My research explores the growing threats of heavy metal and microplastic contamination in Bangladesh’s coastal and river systems. We have investigated pollution hotspots from shipbreaking yards, industrial zones, and agricultural runoffs using advanced techniques like ICP-MS, ICP-OES, FAAS, GF-AAS, HGAAS, CV-AAS and risk assessment modelling.

Studies on rivers including the Halda, Naf, Karnaphuli, Padma, and Meghna, as well as Sandwip Island, Patenga Coast, and the Bay of Bengal coast, revealed that toxic metals, particularly arsenic, lead, cadmium, and chromium, often exceed national and international safety limits. These industrial effluents and shipbreaking activities pose significant ecological and human health risks through drinking water and fish consumption.

We also assessed microplastic pollution in coastal sediments, river water, and sea salts, finding widespread contamination in beaches like Kuakata and Karnaphuli, signalling potential long-term health hazards. Our research calls for stricter pollution control, artificial mangrove plantations to trap contaminants, improved wastewater treatment, and public awareness campaigns.

Please tell us about your innovative water purification technologies

My research focuses on developing affordable, highefficiency water purification technologies to tackle arsenic contamination, one of the most severe drinking water challenges in Bangladesh and beyond. Using locally available waste materials, I’ve developed several innovative adsorbent systems.

Our most successful approach uses Nanostructured Bi-Metallic Biochar made from sugarcane bagasse waste, impregnated with manganese and aluminium. This material achieved nearly 90% removal of arsenic in just over an hour, with a maximum adsorption capacity of 54.95 mg/g, outperforming many conventional adsorbents. The system works through oxidation and

complexation via •OH free radicals, making it both efficient and environmentally sustainable.

These materials are easy to produce and scalable, offering practical solutions for household-level water treatment in arsenic-affected regions. Our work combines nanotechnology, waste valorisation, and green chemistry to design next-generation water purification technologies.

What are the most critical water contaminants in developing regions today?

The most critical water contaminants threatening communities in Bangladesh and many developing regions fall into four major categories:

• Heavy Metals: Arsenic remains the most alarming, affecting millions who rely on shallow tube wells. Lead, cadmium, chromium, and mercury from industrial sources cause cancer, kidney damage, and developmental disorders.

• Microplastics: Increasingly detected in surface water, sediments, and even sea salts from urban waste and industrial discharges, with unknown long-term health impacts.

• Nutrients & Agricultural Runoff: Excess nitrogen and phosphorus cause eutrophication, leading to harmful algal blooms and ecosystem collapse.

• Pathogenic Microorganisms: Bacterial contamination from untreated sewage leads to waterborne diseases like cholera and diarrhoea.

These contaminants create a complex crisis demanding integrated solutions, including pollution control, wastewater treatment, and affordable purification technologies.

How do you use local materials for sustainable water treatment?

My research turns locally available, inexpensive materials into advanced nanomaterials for sustainable water purification. For instance, we used tamarind pulp extract to synthesise magnesium oxide nanoparticles through an eco-friendly route, showing excellent efficiency for removing chromium and arsenic from contaminated water.

Similarly, we’ve developed sawdust-supported nano zero-valent iron, duckweed-based bioadsorbents, and graphene oxide composites. These materials demonstrate high adsorption capacities, reusability, and costeffectiveness for household-level treatment in resourcelimited regions. By using agricultural and industrial waste

Continued on page 12

materials, our work promotes waste valorisation and directly addresses UN Sustainable Development Goal 6.

What does ISO/IEC 17025 certification mean for water quality testing?

My laboratory is accredited under ISO/IEC 17025 for heavy metals testing in water, soil, sediment, fish, and food products. This involves creating a robust quality management system, validating analytical methods, maintaining calibrated instruments, and implementing strict quality control measures.

For water quality testing, this certification ensures test results are accurate, reproducible, and traceable to international standards. In practical terms, communities, industries, and environmental agencies can rely on our data to assess contaminants because the results are scientifically defensible and globally comparable, strengthening public health decisions and pollution control measures.

How are you advancing trace metal analysis for developing world applications?

My work focuses on advancing analytical methodologies for detecting trace and toxic metals in water systems using state-of-the-art techniques like AAS, ICP-OES, and ICP-MS with optimised sample preparation protocols.

What makes our approaches particularly suited for

developing world applications is that we modify methods to minimise expensive reagents while maintaining accuracy. Our techniques work in settings with limited infrastructure while meeting international quality standards. We also explore field-deployable methods for faster decision-making in remote areas.

Why is open access crucial for environmental science?

Open access publishing removes barriers to information, allowing scientists, policymakers, and communities in developing regions to access the latest findings without subscription costs. Water contamination is a global challenge, and unrestricted access to research enables faster adoption of evidence-based solutions and betterinformed public policies.

Open access democratises environmental science, empowering local researchers, students, and NGOs to participate in solving pressing environmental issues. It ensures that critical data on contaminants reaches the people who can use it to protect public health and ecosystems.

What obstacles have you faced as a woman scientist from a developing country?

As a woman scientist from a developing country, I’ve faced challenges including limited research funding,

resource-constrained laboratories, and fewer networking opportunities. Balancing motherhood with a demanding research career has been particularly difficult with two young children and limited childcare facilities.

I’ve navigated these challenges through family support, careful planning, and resilience, while leveraging local materials for research and forming collaborations with international organisations like the IAEA, TWAS, World Bank, and UNIDO. By combining innovation, resourcefulness, and strong support networks, I’ve conducted meaningful research that is both globally relevant and locally impactful.

What advice would you give young women aspiring to careers in environmental science?

Pursue your curiosity fearlessly and seek hands-on experience in environmental science. Build a strong foundation in chemistry, biology, and environmental engineering, complemented by practical laboratory and fieldwork skills. Networking and mentorship are equally important. Connect with scientists, participate in workshops, and seek collaborations to broaden your perspective.

Don’t be afraid to innovate using local solutions, because impactful research doesn’t always require expensive equipment. Above all, believe that your work can make a difference in communities, influence policy, and create positive change. Persistence, creativity, and

collaboration are key to building a successful career in environmental science.

What’s your vision for water technology in developing nations?

My vision is to create affordable, sustainable, and community-centred solutions that can be widely implemented in resource-limited areas through locally sourced purification technologies that are easy to use and scalable.

We need to integrate scientific research with local knowledge, provide training programs, and promote partnerships between governments, NGOs, and international organisations. Open access to research, technology transfer, and supportive policies are key to ensuring that safe, clean water becomes a right rather than a privilege, empowering communities while protecting the environment.

Tech-Powered River Guardians: How WildFish is Using Citizen Science and Smart Tools to Save UK Rivers

WRITTEN BY | NATASHA POSNETT

It’s hard to imagine an essential piece of biodiversity quietly slipping toward collapse, but that is precisely what’s happening in many of the UK’s rivers. While they may still appear tranquil on the surface, beneath lies a story of chronic overextraction, chemical overload and plummeting oxygen levels; conditions that are causing declining ecosystem health and pushing iconic species closer to extinction.

In 2023, the Atlantic salmon was officially reclassified as “endangered” on the IUCN Red List. This is just one species, but it sums up the overall urgency of the situation.

Although traditional government oversight and reactive policies may currently be falling short, citizen science and intelligent monitoring technologies are stepping in to make a real difference to the health of UK rivers.

At the forefront of this new wave of grassroots tech is WildFish, an independent UK conservation charity that champions the protection of wild fish and their freshwater ecosystems. Their flagship initiative, SmartRivers, demonstrates how precision science can meet citizen engagement to close critical data gaps and encourage

regulators into action.

I spoke to Dr Janina Gray, Head of Science and Policy at WildFish, to find out more about the state of our rivers and the work they are doing to help.

“The problems facing UK rivers are urgent, and vary from pollution and abstraction, to the risk of losing aquatic plants and wildlife to extinction. Water companies abstract 700 million litres of water unsustainably from rivers every single day. Combine that with thousands of hours of daily sewage discharge, and you’ve created a perfect storm of low water levels, toxin accumulation and habitat degradation.”

How does SmartRivers Work?

Launched in 2019, SmartRivers is more than a monitoring project, it’s a data-driven movement. By training volunteers to collect high-quality, scientifically robust information on freshwater ecosystems, WildFish is effectively creating a distributed network of water quality watchdogs. The programme focuses specifically on aquatic invertebrates, using what Dr Gray calls

Janina Gray Deputy ceo, wildfish

“invertebrate fingerprinting” as a primary diagnostic tool.

“Unlike nutrient testing, which gives you a snapshot of water quality at one point in time, invertebrates offer a more comprehensive view. They live in the river over weeks and months and integrate the impacts of pollutants over that time. Analysing their presence- or absence- tells us a lot about chronic stressors on the ecosystem.”

Volunteers are trained to collect samples using a standardised three-minute kick-sweep and one-minute hand search method. These samples are then analysed down to the species level, providing information that allows scientists to track biodiversity, identify invasive or threatened species and develop water quality scorecards based on five common stress types.

Over 6,000 hours of volunteer training have already been completed, and the results are proving helpful. The SmartRivers dataset is fully open-access, allowing NGOs, policy advocates and even regulators to use the data for scientific scrutiny and public accountability.

Citizen Science as a Regulatory Force

A perfect indicator of SmartRivers’ impact lies in how its data has been used to influence regulatory decisions.

One success story was from the River Alyn, part of the Dee catchment in North Wales. After SmartRivers volunteers consistently recorded chemical pressure in the area, WildFish used that data to request pesticide usage records from the Health and Safety Executive (HSE). Although initially denied access, the Information Commissioner later ruled that these records are indeed held “on behalf of” the HSE. A legal challenge is ongoing, but its implications are already resonating nationally.

“This legal battle could set a precedent for transparency in pesticide regulation. And it wouldn’t have been possible without the credibility of the data our volunteers collected.”

Another success story comes from Newcastle’s River Ouseburn. During their first monitoring season in spring 2024, Tyne Rivers Trust volunteers discovered the presence of Dikerogammarus haemobaphes- better known as the invasive demon shrimp. The find was swiftly reported to local regulators, prompting an investigation. Such early detections are vital for preventing ecological disruptions and costly mitigation later.

The Next Frontier: eDNA and AI Integration

While the SmartRivers programme already stands out for its methodological rigour, WildFish is actively looking to expand its technological toolkit. One area of promise lies in environmental DNA (eDNA). This is a method that identifies species by detecting trace genetic material in water samples.

“eDNA can spot rare or elusive species that traditional surveys might miss. It’s particularly valuable for early detection of invasive species or monitoring endangered ones like the Atlantic salmon.”

Paired with evolving AI capabilities, eDNA and other digital diagnostics could revolutionise how we track river health. AI, in particular, has the potential to analyse monitoring data in real-time, providing instant alerts for pollution incidents or anomalies in ecosystem behaviour. For citizen science projects like SmartRivers, AI could also help volunteers better understand and interpret their findings, streamlining analysis without compromising accuracy.

These technologies have the potential to be incredibly helpful, but it should also be remembered that they must be implemented with care.

“As with all things in the ‘AI revolution’ this technology requires thorough input and scrutinization by experts from the beginning to ensure that mistakes and erroneous assumptions are not unintentionally perpetuated into future monitoring methodologies.”

Collaboration, Not Competition

What sets WildFish’s approach apart is its emphasis on collaboration. By making data publicly accessible and offering training to partner organisations, the charity fosters a culture of shared responsibility and collective impact. It’s a powerful counter to the fragmented nature of water governance in the UK, where oversight is often split between agencies with, often, insufficient mandates.

“Citizen science doesn’t just fill data gaps. It democratises environmental stewardship. When people are empowered to understand and monitor their local river, they become advocates for its protection.”

WildFish’s mission is simple yet profound: healthier wild fish stocks, restored biodiversity and cleaner, more resilient freshwater habitats across the UK.

Whether it’s pushing for policy change, exposing corporate malpractice or training the next generation of river stewards, WildFish proves that precision technology and grassroots action can work hand in hand.

In an era where rivers are declining rapidly and pollution is outpacing regulation, it’s tempting to believe the situation is too complex to solve. But the work of WildFish reminds us that solutions already exist. They just require good science and a community willing to wade in and do the work.

Against the Odds: Improving Water Quality in Palestine’s West Bank

Written By | MARTYN SHUTTLEWORTH

Although water shortages and the unbalanced allocation of resources in Palestine’s West Bank are well understood, water quality is rarely mentioned. Yet, the critical task of maintaining clean water for drinking and irrigation is increasingly difficult given the delicate political situation.

Sobhi Yaghi, the Water Quality Monitoring Officer at Jericho Municipality, has 15 years of experience testing water resources and ensuring compliance with water quality standards. He tells us how the municipality maintains water quality under difficult circumstances and reveals their future plans.

Could you give us a background to Jericho and its water resources?

Located in the Jordan Valley, Jericho—known in Arabic as Ariha—is one of the world’s oldest continuously inhabited cities with between 35,000 and 38,000 residents. The city lies 250–260 meters below sea level, making it one of the lowest and warmest inhabited places

on earth. The hot, arid climate with high evaporation rates and scarce rainfall, averaging less than 150mm annually, poses significant challenges for sustainable water resource management.

The city relies almost entirely on groundwater with its primary source, Ein Sultan Spring, providing an average flow rate of 750 cubic meters per hour. A number of groundwater wells, pumping stations, storage reservoirs, and distribution pipelines complement the municipal water supply. The water network supports extensive agriculture, accounting for over 60% of total water use, domestic consumption of 35%, with small-scale industries and services consuming the remainder.

Jericho is renowned for its rich historical significance, attracting tourists through its natural landscapes, hot springs, and ancient ruins. This combination of cultural heritage and water resource challenges makes Jericho a unique case study for integrated water quality and resource management in arid/semi-arid environments.

Sobhi Yaghi Deputy ceo, wildfish

How do you monitor water quality and spot potential problems?

Water quality monitoring is fundamental to our water management strategy. The Jericho Municipality Water Quality Laboratory undertakes sampling, laboratory analysis, and data evaluation using internationally recognized protocols to give accurate and reliable results.

We collect water samples on a regular schedule from different points — including groundwater wells, the municipal drinking water network, irrigation systems, and treated wastewater outlets. The municipal laboratory analyses these for key physical, chemical, and microbiological parameters such as salinity (electrical conductivity), pH, turbidity, residual chlorine, nitrate, heavy metals, and bacterial indicators (total coliforms and E. coli).

In addition, specialized analyses in accredited external laboratories ensure compliance with national and WHO standards. Our dedicated wastewater laboratory performs routine checks because 65% of treated wastewater is reused for irrigating date palms.

To predict potential problems, we rely on historical water quality data, seasonal trend analysis, and GIS-based mapping of contamination risks. For example, we monitor salinity fluctuations during dry seasons, track industrial discharge patterns, and assess potential impacts from agricultural and urban activities. Sudden deviations in parameter readings trigger immediate field investigations and corrective measures in coordination with environmental authorities. This proactive monitoring framework supports preventive strategies that protect public health and sustain the region’s scarce water resources.

Some of the problems and solutions include:

Salinity and Dissolved Solids

Groundwater wells in the Jericho area show highly variable total dissolved solids (TDS), ranging between 800 and 2,500 (values fluctuate between wells and over time in the same well). By contrast, the Ain Sultan Spring exhibits much lower TDS of about 380.

High and variable salinity is driven by over-extraction, limited recharge, and local hydrogeological conditions, and affects drinking water quality and agricultural productivity. To manage salinity and TDS, we:

• Actively blend lower-salinity spring water (Ain Sultan) with higher-salinity well water before distribution to keep overall salinity within acceptable limits.

• Monitor TDS continuously to detect spikes, regulate abstraction rates to prevent further intrusion, and promote salt-tolerant crops and efficient irrigation.

Industrial Contamination/Pollutants

A significant portion of industrial pollution in Jericho stems from the desalination units used by local manufacturers, which discharge brine into municipal sewers. In the wastewater treatment plant, the high salinity disrupts the biological processes — particularly the bacteria essential for breaking down organic matter — reducing treatment efficiency and compromising effluent quality. To combat this, we:

• Work with industrial operators to implement proper brine management including on-site pre-treatment, controlled disposal outside the sewer network, or reuse in non-sensitive industrial or agricultural applications.

• Coordinate with regulatory bodies to establish guidelines and enforce local regulations requiring factories and saline well operators to dispose of brine safely through specialized treatment systems.

• Conduct awareness campaigns on the impact of brine on wastewater treatment.

• Continuous monitoring of salinity at key points in the sewer system to identify high-load discharges and take immediate corrective action.

Aging Infrastructure/Corrosion

Many municipal water pipes and storage tanks in Jericho are decades old, and often made of galvanized steel or asbestos-cement. Corrosion leads to iron, manganese, and rust particles leaching into the water, causing discoloration, unpleasant taste, and health risks. Old joints and cracks also allow infiltration of contaminants from soil or sewage lines. We implement:

• Gradual replacement of old pipelines with modern PVC, HDPE, or ductile iron pipes, and lining/ rehabilitating storage tanks with corrosion-resistant materials.

• Implementing a preventive maintenance plan and leak detection system to minimize pipe failures.

Poor Wastewater Treatment

Approximately 35% of Jericho’s population remains unconnected to municipal sewers and relies on cesspits or uncontrolled discharge, so untreated wastewater infiltrates groundwater or nearby wadis. We want to:

• Expand the sewer network to cover all unserved areas, particularly peripheral communities.

• Upgrade Jericho’s wastewater treatment plant to include tertiary treatment processes and dedicated systems for managing high-salinity brine prior to

entering biological treatment units.

• Establish decentralized wastewater treatment units in areas difficult to connect to the main network, such as constructed wetlands or compact modular treatment plants.

Lack of Data

There is a shortage of reliable, up-to-date water quality and quantity data in Jericho. Existing records are often fragmented, outdated, or incomplete, making it difficult to assess current conditions, identify trends, or respond to emerging issues. We intend to:

• Establish a continuous water quality monitoring network using online sensors to track key parameters such as pH, turbidity, conductivity, residual chlorine, and temperature.

• Develop a centralized digital water quality database accessible to relevant authorities, municipalities, and laboratories.

• Implement regular and standardized sampling protocols, including advanced laboratory testing for chemical, microbiological, and emerging contaminants.

• Train municipal staff and water operators in rapid field testing, data recording, and early warning response procedures.

Other Issues

To counteract discharge from Israeli settlements, we intend:

• Continuous monitoring of inflow points from upstream areas.

• Engagement with international organizations to enforce wastewater treatment standards.

• Construction of local interception and treatment systems where required.

For over-abstraction of groundwater, we support:

• Introduction of pumping quotas and improved monitoring of abstraction rates.

• Promotion of alternative water sources, including treated wastewater for irrigation.

• Initiation of managed aquifer recharge projects to prevent saline intrusion.

Finally, to combat agricultural runoff, we want to:

• Implement of Integrated Pest Management (IPM) and precision fertilization.

• Establish of buffer zones between farmlands and

water sources.

• Promote of environmentally friendly farming practices.

What are the main barriers?

Political difficulties mean a limited control over upstream sources, including settlements, which complicates the enforcement of wastewater regulations. Coordination with multiple authorities and international organizations can be slow and challenging.

The lack of financial resources limits rehabilitation and expansion projects, and makes it difficult to upgrade infrastructure, modernize treatment plants, and install monitoring systems. A lack of expertise and trained personnel in advanced water treatment, monitoring technologies, and aquifer recharge techniques requires continuous capacity-building programs for municipal staff and local engineers.

Other barriers include limited understanding of water conservation and pollution prevention among the public and water users. Technical limitations include challenges in accessing certain groundwater sources or implementing Managed Aquifer Recharge (MAR) projects due to geological conditions. Finally, environmental factors mean saline intrusion and seasonal fluctuations in water availability can restrict solution effectiveness.

What organisations do you work with?

Jericho Municipality collaborates with several organizations to improve water quality, support infrastructure development, and enhance water management. Nationally, the Palestinian Water Authority (PWA) and Palestinian Environmental Quality Authority (EQA) work together. Local NGOs and Research Centres implement awareness campaigns, community engagement, and technical studies related to water quality. A number of international organisations offer technical support, funding, and guidance, including:

• United Nations Development Programme (UNDP):

• United Nations Relief and Works Agency (UNRWA):

• European Union (EU) and Donor Agencies:

• World Health Organization (WHO):

• Japan International Cooperation Agency (JICA):

• United States Agency for International Development (USAID):

• International Water Management Institutes (IWMI, GIZ, etc.):

These partnerships help Jericho Municipality address water quality challenges, implement modern technologies, and comply with international standards.

What new technologies/processes would you like to adopt?

There are a number of new technologies and improvements we would like to see:

Advanced Water Treatment Technologies

• Reverse Osmosis (RO) and Nanofiltration: To treat brackish groundwater and high-salinity water sources.

• Advanced Oxidation Processes (AOPs): For removal of micropollutants, pharmaceuticals, and emerging contaminants.

• Smart Disinfection Systems: Automated, sensorcontrolled chlorination or UV disinfection to maintain safe water quality levels.

Smart Water Monitoring and Management

• SCADA and IoT-based Systems: Real-time monitoring of water quality, pressure, and flow across the distribution network.

• Automated Leak Detection: AI-based sensors to detect and locate leaks rapidly, reducing water loss.

• Centralized Data Management Platforms: Integration of GIS, water quality, and usage data for decision-making and predictive maintenance.

Sustainable Groundwater Management

• Managed Aquifer Recharge (MAR): Controlled infiltration of treated wastewater to replenish aquifers and prevent saline intrusion.

• Aquifer Storage and Recovery (ASR): Temporary storage of surplus water for seasonal use.

• Groundwater Modelling Tools: Advanced software for simulation, prediction, and scenario planning.

Energy-Efficient and Eco-Friendly Solutions

• Solar-Powered Pumping Systems: Reducing dependency on electricity and diesel for water abstraction.

• Green Infrastructure for Stormwater Management: Constructed wetlands and bioswales for natural treatment and recharge.

• Resource Recovery from Wastewater: Nutrient recovery and sludge-to-energy processes to create circular economy benefits.

Community Engagement and Digital Solutions

• Smart Metering and Consumption Feedback: To promote water conservation among households and farms.

• Digital Platforms for Public Awareness: Mobile apps and dashboards to report issues, provide alerts, and share water-saving tips.

In line with the challenges and future aspirations, I am considering a doctoral thesis exploring innovative strategies for enhancing groundwater resources in arid and semi-arid regions with treated wastewater and industrial effluents.

From Disaster Relief to Lasting Change: The Global Impact of Planet Water’s Filtration Technology

INTERVIEWED BY | DARBY BONNER

The genesis for Planet Water Foundation was the 2004 Indian Ocean Tsunami. Planet Water’s founder, Mark Steele, was at that time working for U.S.-based ITT Industries, overseeing the company’s operations in China, and as part of the company’s CSR work, took on the role of leading the company’s response to the devastation caused by the tsunami in Sri Lanka. This had a profound impact and led to Mark’s desire to focus his efforts on addressing issues around access to safe water and, ultimately, founding Planet Water Foundation in 2009.

From here, Mark designed and created the AquaTower water filtration system, which has since been deployed in over 2,000 communities around the world, particularly in underserved areas. Along with this, subsequent water filtration solutions were designed for rapid response in the wake of natural disasters where access to safe drinking water is of critical, urgent need.

Planet Water’s AquaTower Technology

The AquaTower was developed to be a robust water filtration system which can operate in areas where infrastructure is very basic or lacking entirely. The system is designed to use minimal electricity, utilising a small electric pump. In some cases, a treadle pump brings the water source to the tank, and from there, the system functions by gravity. The AquaTower pulls in water from sources such as ponds and borewells, which are usually quite badly contaminated with faecal bacteria or agricultural waste.

Over the years, based on the observations made through Planet Water’s project sustainability program and feedback from the communities its supported, they have continually enhanced the design of the system - from incorporating anodized aluminium and marine grade stainless steel to form the system’s key structural elements, to continued enhancements in filtration process

Mark steele Founder, Planet water

and technology, to the addition of handwashing infrastructure with liquid soap dispensers.

Planet Water have also innovated with new solutions, like its AquaBlock Emergency Water Filtration System, which was explicitly designed in the context of disaster response. These turnkey systems are designed to be rapidly deployable in evacuation centres following natural disasters and provide enhanced filtration capabilities to serve larger numbers of people.

Disaster Response Strategy & Long-Term Water Solutions

To expedite their response process, they have launched the Planet Water Foundation Disaster Response Alliance, a programme that enables companies to pre-fund its disaster response work. Planet Water then provides its program partners with the option to opt in or out of any response they undertake, allowing them to apply funding accordingly. This allows Planet Water to position its AquaTower and AquaBlock systems in logistics hubs around the world, enabling Planet Water to respond quickly in the event of a disaster.

In terms of how they respond, Planet Water tailors its response based on the unique circumstances of each event. Every event presents its own set of challenges. For example, in Asheville, North Carolina, following Hurricane Helene, whilst the water systems were seriously affected, most community members were still able to stay in their homes. As such, Planet Water focused on positioning its AquaBlock systems in locations that were easily accessible to residents who drove by car to fill containers with safe drinking water. These locations were either in centres where non-potable water was being trucked in, or next to creeks, which they would use as source water. By contrast, following the earthquake in Myanmar earlier this year, many residents had lost their homes and had relocated to tented camps. As such, Planet Water focused its deployments on those camps.

With all of Planet Water’s responses, the team plans to provide ongoing support as needed. For example, in Asheville, its AquaBlock systems were in the field for three months, until the municipal water supplies were fully restored and deemed safe to drink. In Myanmar, many of the relocation camps were set up in schools, and so its AquaTowers will have a second life providing safe water to the school once the camps are closed.

Regional Focus and Expansion

Planet Water’s school-based projects are focused on Asia and Latin America. In its operational countries in these regions, there is still a lot of support needed in terms of expanding access to safe drinking water. As such, Planet Water are not actively looking to expand into new regions

due to the high investment costs required to enter a new country.

Planet Water’s Disaster Response work is global, though. For example, they have supported responses to disasters in Africa (Morocco and Libya), Europe (Ukraine and Turkey), and the USA. Suppose a disaster occurs in a country without team members. In that case, Planet Water has a detailed checklist that they run through to assess feasibility – i.e., can Planet Water find a local deployment partner, ship its water filtration systems into the country, and mobilise quickly, among other factors.

How Planet Water Hopes to Meet Changing Global Water Challenges

Planet Water are constantly looking at how it can leverage new technologies to enhance the impact it makes. They are currently field testing a new version of their AquaBlock emergency water filtration system and exploring ways to provide beneficiaries in disaster response scenarios with receptacles to collect and store the safe water they collect from the AquaBlock. Planet Water will also be launching an exciting new solution later this year to be added to its Disaster Response offering. Stay tuned for more information on that!

Finding Oil Spills with Poppy:

Are Sniffer Dogs the Answer?

Written By | MARTYN SHUTTLEWORTH

At H2O Global News, we love dogs and make no excuses for including a story about one of our furry friends. Especially when she is doing a great job finding oil spills and keeping freshwater lakes pristine. Poppy, a beautiful Springer Spaniel working in Canada’s IISD Experimental Lakes Area, puts her nose to good use snuffling out oil hidden under ice. To find out more, we interviewed Sumeep Bath, who told us more about the role sniffer dogs can play in water quality.

Sumeep Bath communications manager for IISD Experimental Lakes Area

Could you tell us about yourself?

I'm Sumeep Bath, and I'm lucky enough to be the communications manager for IISD Experimental Lakes Area, the world’s freshwater laboratory. Seriously, my science communication friends are a little jealous! I love this role because I can reach different audiences, whether I'm writing a serious policy brief or making a fun TikTok.

The best part? The place itself is incredibly photogenic, and the organization understands the value of communicating its work to the outside world.

What is the IISD Experimental Lakes Area?

IISD Experimental Lakes Area (IISD-ELA) is a one-of-akind natural laboratory. It's made up of 58 pristine lakes and their watersheds in a remote area of northwestern Ontario, Canada, where they're completely untouched by human activity.

This unique setting allows scientists to manipulate entire lakes to study how everything in the ecosystem—from the air to the fish—responds. Because these are real-world experiments, the findings are more accurate and reliable than research conducted in smaller, lab-based settings. This approach led to groundbreaking discoveries that have influenced billion-dollar decisions by governments and industries, shaping cost-effective policies and regulations to safeguard freshwater resources.

Why are oil spills such a problem and why are they difficult to detect?

An oil spill is the unintentional release of oil into the environment during transport via trucks, rail, or pipelines, which can contaminate freshwater ecosystems. In North America, one common type of oil transported is bitumen from the Alberta oil sands. Because bitumen is too thick to flow through pipelines, it's diluted with lighter oils to create a mixture called diluted bitumen or "dilbit."

Northern Canada is particularly vulnerable to oil spills, as pipelines and rail lines often cross frozen waterways. Spills in these remote, ice-covered areas are incredibly difficult and expensive to detect. Traditional methods require heavy machinery for drilling or underwater navigation, making the process time-consuming and challenging. Detecting these spills is vital to preventing devastating economic and ecological impacts.

Continued on page 24

How can sniffer dogs help?

Dogs have an incredible sense of smell, which is why they work in places like airports. A dog's nose has up to 300 million scent receptors, while a human's has only about six million. The part of a dog's brain that processes smells is also 40 times bigger than ours.

Essentially, dogs "see" the world with their nose. That's why using trained dogs to find oil spills is so effective—it's a new application of a skill they've always had.

What are the advantages of using sniffer dogs?

Recent research at the IISD Experimental Lakes Area yielded excellent results: specially trained detection dogs successfully located two different types of oil under lake ice in a double-blind study. In all six trials, the dogs correctly identified the oil's location with no false negatives.

This is a significant breakthrough. Current technologies for detecting oil under ice—such as ground-penetrating radar and remote or autonomous underwater vehicles— are slow and extremely expensive, with some systems costing up to $6 million plus daily operating fees of $30,000.

While canine detection has not yet proven effective in complex urban environments, this research highlights the growing potential for using dogs in environmental surveys.

How long did it take to train Poppy?

Poppy, a detection dog specializing in environmental surveys, was trained by Paul Bunker, a British Army veteran and founder of Chiron K9. With over 40 years of experience with working dogs, Bunker began training Poppy as a puppy after receiving her as a gift.

The training process is straightforward. A target scent— like oil, explosives, or even endangered species—is paired with a reward, such as a squeaky tennis ball or a treat. For Poppy, this makes the work feel like a game. When she successfully hunts down and finds the scent, she's rewarded, reinforcing the desired behaviour.

Have you any plans to expand the programme?

A representative from the Wiikwemkoong First Nation on Manitoulin Island contacted us for help finding several undocumented and abandoned oil wells. Following the story, they reached out to see if our oil-sniffing dog team could assist. Our head scientist, Vince Palace, is currently in discussions to determine how our technology can help.

Perhaps the most important question: What is Poppy’s favourite treat?

For Poppy, her favourite squeaky tennis ball is the ultimate reward. It's not just a treat; it's the payoff for a job well done. When she successfully finds an oil spill, we celebrate her success together, and she gets to play with her ball, making the whole process a fun game.

Reimagining Water Treatment:

How Low-Tech Innovation is Raising Water Quality Standards in Underserved Communities

WRITTEN BY | NATASHA POSNETT

In many parts of the world, conventional water treatment systems remain out of reach. They’re either too costly, too complex, or too dependent on unreliable power infrastructure. But AguaClara Reach, a nonprofit engineering organisation, is working to change that by reimagining what clean water technology can look like in underserved communities. Their work couldn’t be happening at a more important time with around 2.2 billion people around the world still lacking access to safe drinking water (UNICEF), and approximately 3.5 million people dying each year due to inadequate water supply, sanitation and hygiene (United Nations).

At the heart of AguaClara’s mission is an exciting vision: delivering high-quality water using low-tech, sustainable and locally adaptable systems. It’s a vision that’s already proving very effective. Not only is it helping to improve health outcomes, it is transforming entire communities.

Designed for Reality

AguaClara’s plants are engineered specifically for the realities of rural and resource-limited settings. They design water treatment plants to remove harmful pathogens and particles, but also focus on providing a resilient and reliable design. Simplicity is key.

The primary threats to water quality in many of the regions AguaClara serves include microbial contamination and sediment-laden turbidity from erosion. Their systems are engineered specifically to address these challenges without relying on imported components or complex maintenance. In rural settings where untreated surface water is often the only available source, AguaClara’s simple, robust systems offer a practical lifeline. The ability to process highly turbid water and reduce pathogen risk without relying on electricity is a wonderful technological achievement.

Cheer Tsang, one of the Board of Directors at

Cheer Tsang director of the board at AguaClara

AguaClara Reach, was able to explain more about the technology:

“Conventional high-tech water treatment technologies combine software, sensors and mechanised controls for plant operation. These systems require many moving specialised parts that inevitably break. Too often, the result is that the entire plant is abandoned after a few years. However, at AguaClara Reach we use very few moving parts, which decreases failure modes. We also use local materials and labour, making the plant less expensive to build, maintain and operate. No electricity is required to operate our plants, ensuring reliable treatment.”

This approach has enabled AguaClara to address not just technical challenges but also critical social issues, such as gender inequality and public health.

“In the communities where an AguaClara plant has been installed, readily available safe water on tap eliminates the need for people to travel for miles to fetch water or to purchase bottled water at higher prices. As this burden often falls on women and girls, the time spent traveling to and from a water source can prohibit girls from receiving an education.”

Engineered for Sustainability

AguaClara Reach is committed to long-term sustainability. All the core treatment processes are designed to work entirely without electricity and they encourage local adaptation to ensure communities have both the knowledge and the tools to maintain their own systems.

“These processes have been developed and optimised through decades of research and can consistently treat raw water with a turbidity up to 1000 NTU to a finished effluent of less than 1 NTU. The open-source design, consisting of non-proprietary materials with few moving parts, makes long-term treatment system operation and maintenance affordable.”

A powerful example of this can be found in Honduras, where AguaClara has helped build over 20 gravitypowered water treatment plants serving tens of thousands of people. Each system is operated by a local water board trained in the operation and maintenance of the plant. The boards collect small user tariffs (affordable and scaled to income levels) which fund upkeep, repairs, and salaries for operators. This has resulted in systems that are still running smoothly over a decade after installation. More importantly, they are fully owned by the communities themselves, transforming water access from a temporary aid project into a permanent public service.

A New Model for Global Water Access

AguaClara’s work raises an important question for the future of water treatment. Should more regions be focusing on accessibility and eliminating complexity?

“We see technology evolving as a way to close the gap between communities that already have safe, reliable water and those that have been historically left behind. Many conventional water technologies are too complex, costly or dependent on electricity and imported parts, which makes them difficult to sustain in rural or resourcelimited settings.”

Instead, AguaClara is pioneering a model of technology that is simple to operate, built from locally available materials and designed to run on gravity. Their systems represent a powerful example of how thoughtful, lowtech engineering can offer reliable and scalable solutions.

“The most impactful technologies will be those that are open-source, adaptable to different water quality challenges, and designed with long-term sustainability in mind.”

In a world racing for high-tech fixes, AguaClara proves that sometimes the most radical innovations are the ones that let gravity (and local communities) do the work.

Quality Technology Share Their Vision

Leading voices in water technology share their insights on the innovations, challenges, and breakthroughs shaping the future of water quality. From AI-driven monitoring systems to next - generation treatment solutions, our expert contributors reveal what’s driving progress in this critical field and where the industry is headed next.

Nina Bader

Foresight Canada manager, water

What emerging water quality monitoring technology excites you most and why?

Some of the most exciting water quality monitoring technologies revolve around real-time, on-site sensor networks combined with AI-powered analytics, particularly those that can detect contaminants like PFAS, algal blooms, and microbial threads at very low concentrations. This technology is especially vital in Canada, where a vast geography, harsh climates, and outdated infrastructure in remote and Indigenous communities present major challenges. Climate change intensifies these issues, causing sudden shifts in water quality. While traditional lab tests are slow, AI-enhanced sensors provide immediate alerts, allowing for a proactive—rather than reactive—response. This innovation ensures safe, equitable access to clean water by overcoming geographic and infrastructural barriers.

How is AI or data analytics changing the way we assess water quality today?

AI is transforming water management by making it faster, smarter, and more community-focused. Paired with real-time sensors, AI reduces the need for slow and costly lab testing, providing immediate insights into water quality. This allows remote and Indigenous communities to manage their data locally, strengthening data sovereignty. Furthermore, AI’s predictive capabilities are crucial for proactive management. It can forecast changes based on environmental data, helping operators prevent issues like nutrient spikes after rain. In cities, AI models can predict combined sewer overflows (CSOs), giving utilities time to adjust systems and protect public health. Ultimately, by leveraging AI water systems can become more resilient and better serve communities.

What’s the biggest challenge facing water treatment technology right now?

A significant challenge in water management is the adoption of new technology in rural and Indigenous communities. These communities face very different challenges than those of larger municipalities. Unlike large urban centres, these areas need solutions that are modular, low-maintenance, and resilient to harsh climates. Technologies that perform well in municipal plants often aren’t optimized for small-scale, low-maintenance, or intermittent-operator setups with limited technical capacity for monitoring, maintenance, and operation. Funding is often project-based and overlooks crucial long-term costs, and complex procurement processes can put smaller municipalities at a disadvantage. However, solutions like remote monitoring, AI-assisted automation, and co-developing technologies with local communities can bridge these gaps. This strategic approach to water technology not only addresses immediate health and safety issues but also fosters local job creation and supports reconciliation, building a more equitable future.

Richard B. Brown e-SENS

Distinguished Prof. and Emeritus Dean of Engineering, Univ. of Utah and CEO of e-sens, Inc.

What emerging water quality monitoring technology excites you most and why?

The portable e-sens ROAM instrument is ideal for water quality testing in the distribution system. It requires no sample preparation, reagent handling, or maintenance, and produces no consumables waste. It self-calibrates and runs multiple tests from a single water sample in a fully-automated process. It flags anomalies and securely uploads test results, time-stamps, and geotags in real time.

How is AI or data analytics changing the way we assess water quality today?

With more than half of water quality technicians still using pen and paper to record data, there is a great opportunity to improve data integrity. In this twenty-first century, the full power of encrypted electronic communication, databases, data analytics and data science can be employed to optimize water utility management.

What’s the biggest challenge facing water treatment technology right now?

An aging workforce and challenges recruiting skilled technicians present ongoing challenges in the water industry. These can be addressed through adopting advanced technologies that are simple to use and eliminate operator error.

Which water quality innovation do you think will have the greatest impact in the next 5 years?

The integration of more accurate water quality sensors and real-time data analytics will improve water quality, decrease operational costs, and significantly reduce the incidence of boil orders.

What role does real-time monitoring play in preventing water quality crises?

Real-time data is critically important in managing a data-driven system, and not just data from a few in-line sensors. Field-collected data should also be uploaded in real time into a database that employs full analytics to alert operators to issues that need immediate attention.

What advice would you give to communities looking to adopt new water quality solutions?

Take advantage of the technology that is now available to operate a safe, reliable, efficient water treatment and distribution system. The industry now has opportunities to benefit from the developments made in recent decades in chemical sensors, semiconductors, computing, microfluidics, and artificial intelligence. It’s a great time to be in the water industry!

Bill denyer

Envirogen Group

European

CEO

What’s the biggest challenge facing water treatment technology right now?

Groundwater quality is under growing pressure from multiple sources. Not just nitrate runoff from fertilisers, but also pesticides and toxic industrial chemicals that persist in aquifers for decades. At the same time, over-extraction and climate pressures are reducing the availability of clean water. Reverse osmosis systems can waste up to 30% of the feed water, and even traditional ion exchange (IX) creates 2-6% waste. The challenge is finding solutions that don’t worsen the problem. Regenerable IX systems such as Envirogen’s SimPACK remove nitrates effectively while generating up to 80% less wastewater, with waste volumes as low as 0.2%.

What role does real-time monitoring play in preventing water quality crises?

Real-time monitoring is key to sustainable groundwater management. According to the European Environment Agency (EEA), data on aquifer quality, pollution sources, and changing conditions are essential for deploying the right treatment technologies. In regen-IX systems, sensor data can track nitrate levels, optimise regeneration cycles, and reduce unnecessary chemical use. When monitoring and automation are combined, treatment becomes adaptive by responding in real time to changing water quality conditions to ensure consistent performance.

How do you see water quality technology evolving to address climate change impacts?

Water quality technologies will need to adapt to extremesdrought, flooding, and rising nitrate levels. Regenerable ion exchange offers low-energy, low-waste treatment, with some systems now generating as little as 0.2-0.5% wastewater during regeneration. Combined with predictive tools and aquifer monitoring, these technologies are well-suited to decentralised or off-grid applications, particularly in areas where infrastructure is limited and resilience is essential for long-term groundwater security.

How do you balance cost-effectiveness with cutting-edge innovation in water quality solutions?

By taking a life cycle cost (LCC) approach, we look beyond upfront capital to assess the total cost of ownership, including operations, maintenance, energy, chemicals, and system longevity. Whether it’s groundwater remediation, industrial process water, or municipal reuse, effective solutions must combine performance, reliability, and sustainability. With the right design, data, and delivery model, innovative technologies become more than viable – they become cost-effective over the full project life, regardless of scale or sector.

Eyal Harel

BlueGreen Water Technologies CEO and Co-founder

How is AI or data analytics changing the way we assess water quality today?

AI and data analytics enable continuous, large-scale monitoring of water bodies by analyzing satellite imagery, weather patterns, and sensor data. These tools provide early warnings for contamination events, detect patterns invisible to the human eye, and improve response accuracy. The shift from manual water sampling to intelligent analytics allows water managers to act faster, optimize treatment strategies, and protect ecosystems more efficiently and supports proactive long-term planning and sustainability.

Which water quality innovation do you think will have the greatest impact in the next 5 years?

In the next five years, the greatest impact will come from innovations that enable data centers to capture, measure, and recycle cooling water. As aquifers dry and water shortages intensify, especially inland, large-scale water reuse, like turning wastewater into a closed-loop system, will be essential for sustainability and resilience. This shift will require new infrastructure, smarter volumetric measurement, and stricter policy frameworks to preserve freshwater and reduce environmental strain from industrial water use.

What role does real-time monitoring play in preventing water quality crises?

Real-time monitoring provides immediate insights into changing water conditions, allowing detection of dangerous trends like harmful algal blooms or water quality changes that threaten ecosystems. This rapid feedback loop supports timely intervention before issues escalate into public health, ecological, or economic emergencies. By replacing static, delayed data with continuous awareness, real-time monitoring helps safeguard water resources and builds resilience against emerging environmental threats. It enables faster, smarter decision-making.

What’s one water quality technology breakthrough that deserves more attention?

Real-time, predictive technology for harmful algal bloom (HAB) detection and remediation. HABs contaminate drinking water, harm biodiversity, and devastate local economies reliant on fishing and tourism. Traditional monitoring methods are reactive and often too late to prevent damage. Advanced, always-on forecasting platforms predict where and when blooms will grow, shift, or collapse, enabling timely, targeted intervention. This proactive approach transforms HAB response, helping safeguard ecosystems, protect public health, and build resilience amid growing climate and water crises. It’s a vital tool for billions who depend on clean, safe water. As water systems face mounting stress, scalable, data-driven solutions like this will be critical for early intervention, policy action, and long-term sustainability.

Andy Hazlewood

Process Instrument Solutions Director

What emerging water quality monitoring technology excites you most and why?

The most exciting technology is probably not the sensing but the visibility and manipulation of data. In the past, the ability to measure in real time was the game changer, now it is what you can do with that data and how you can use it to give more insight and control of your process.

How is AI or data analytics changing the way we assess water quality today?

From my perspective, AI is still very much in it’s infancy. Whilst it’s future capability and potential is massive, we are yet to see it’s impact in the water industry.

What’s the biggest challenge facing water treatment technology right now?

I would say that data security poses a significant challenge, there are still a lot of questions around allowing data to drive the control of processes without total confidence of security. The other potential issue is everything that is not measured, how can we truly know the water quality is we are not measuring parameters that unmeasured or even unmeasurable.

Which water quality innovation do you think will have the greatest impact in the next 5 years?

Without doubt, real time control. If we can continuously monitor and continuous adjust the process we can ensure the optimal water quality.

How can communities better integrate new water quality technologies into existing infrastructure?

Investment. We cannot continue to avoid investing in technology. The fact is that many new technologies can have a return on investment, we need to be more pragmatic in our approach to funding. If we can prove that the investment will provide optimisation or efficiency, the up front investment should be easy to justify.

What role does real-time monitoring play in preventing water quality crises?

The simplest analogy is driving in the rain without using your windscreen wipers. Real time monitoring provides the clarity that is required to make the right decisions and to continue in the right direction.

Louis Lebrun

Axine Water Technologies Vice President of Sales

How is AI or data analytics changing the way we assess water quality today?

AI’s greatest advantage is the speed at which it can evaluate and draw conclusions from enormous amounts of monitoring data. The greatest challenge to its implementation is limited access to historical operating records and water quality data to appropriately train a model. Overcoming this requires a significant investment of time and infrastructure that many facilities simply do not have.

Axine Water Technologies uses various machine learning and AI models to optimize system performance to achieve benefits that we share with our customers. We can do this effectively because of dedicated staff and properly designed data infrastructure.

What’s the biggest challenge facing water treatment technology right now?

The uncertainty in current and future water quality regulations is making it difficult for utilities to make timely decisions. Faced with changing goals and deadlines, many sites are adopting a “wait and see” approach until State level regulations are fully in place. While this is certainly a logical response, it delays addressing present water quality concerns, pushes even more uncertain costs down the road, and could create greater future challenges to meeting compliance deadlines.

What advice would you give to communities looking to adopt new water quality solutions?

The most important aspects of adopting new water quality solutions are a thorough understanding of water quality treatment needs and goals coupled with an honest evaluation of the customer’s limits on site, operating capacity and budget. All of this discernment work should be done before considering available solutions, which can save time and money, achieve regulatory compliance, reduce risk and avoid stakeholder frustration.

What’s one water quality technology breakthrough that deserves more attention?

The rapid evolution of electrochemical water treatment technologies offers a significant leap in water treatment performance for many applications. Although the core technology has been around for decades, the incorporation of advanced materials science and process controls technology have made the process extremely practical and cost effective to deploy.

How is AI or data analytics changing the way we assess water quality today?

In my work with UK water companies, I’ve seen firsthand how AI and data analytics are shifting the industry from reactive problem-solving to proactive prevention. Traditionally, water quality assessment relied on scheduled testing and manual reporting, often leaving operators to discover issues after the damage was done. Today, AI allows us to analyse real-time operational data, spotting anomalies and predicting potential incidents before they escalate. AI-driven frontline intelligence tools, like FYLD, brings control rooms, field teams, and contractors onto one connected platform, giving utilities live visibility of their networks and the ability to respond quickly and confidently to emerging risks.

What role does real-time monitoring play in preventing water quality crises?

Real-time monitoring is critical—it’s the difference between catching a small issue and facing a major pollution event. When utilities can see problems unfolding live, they can coordinate field crews and contractors instantly, preventing environmental damage and regulatory breaches. Having the right technology in place can equip teams with evidence-led insights and immediate operational oversight, so decisions are no longer based on guesswork. This speed and clarity reduce both response times and the risk of escalating incidents, ultimately protecting water quality and public trust.

How do you see water quality technology evolving to address climate change impacts?

Climate change is driving unprecedented operational challenges—more intense storms, longer droughts, and unpredictable network stresses. The future of water quality management lies in adaptive, intelligence-led systems. By continuously analysing environmental and operational data, AI will guide utilities toward predictive, rather than reactive, management. In my work FYLD, we’re focused on enabling water companies to build this resilience—protecting the environment, maintaining compliance, and ensuring reliable service even as conditions grow more volatile.

What’s the biggest challenge facing water treatment technology right now?

One of the most pressing challenges in water treatment today is addressing widespread contamination from PFAS, or “forever chemicals.” These highly durable synthetic compounds are found in water, soil, air, food, indoor environments, and human blood. Linked to serious health risks, including cancer and hormonal disruption, PFAS have infiltrated the water cycle and are deeply embedded in the global supply chain. In the United States alone, at least 100 million people have PFAS-contaminated drinking water. Existing infrastructure was not designed to remove these compounds, and the lack of comprehensive regulations and effective treatment solutions hinders critical investment in new technologies.

What role does real-time monitoring play in preventing water quality crises?

Real-time monitoring is a game-changer in preventing water quality crises by shifting our approach from reactive to proactive. Instead of discovering a problem days later with traditional lab samples, real-time sensors provide instant data on contaminants and other key parameters. This immediate detection enables swift responses, preventing contamination from spreading downstream and causing greater harm to drinking water supplies and ecosystems. It serves as the critical early warning system that protects public health, reduces cleanup costs, holds polluters accountable, and provides communities with the robust, instantaneous data needed to act decisively.

Smarter, Safer, and Greener: Enhancing Water Quality with Xylem Treatment Solutions

In a world facing growing environmental pressure, the way we treat water is evolving. From industrial operations to municipal plants, operators are not only expected to meet stringent water quality regulations—they’re also being called to do so more sustainably and efficiently than ever before.

Xylem offers a powerful portfolio of advanced water and wastewater treatment equipment, helping customers safeguard their operations while reducing environmental impact. Whether you require a permanent setup or a rapid-response solution during maintenance or emergency situations, Xylem ensures that water quality is never compromised.

Advanced Treatment with UV, Ozone, Filtration and DAF

Today’s water challenges require a move away from conventional chemical-based disinfection toward greener, safer alternatives. Ultraviolet (UV) and Ozone (O₃) technologies—two naturally occurring, non-chemical methods that offer robust, proven disinfection without harmful by-products.

These solutions are ideal across sectors, from municipal utilities to food and beverage manufacturing. UV treatment inactivates microorganisms like Cryptosporidium and Legionella without altering water composition or producing toxic residues. Meanwhile, Ozone offers a powerful oxidizing effect—50% stronger and 3,000 times faster than chlorine—making it an exceptional solution for

industries where hygiene and shelf life are critical.

High TSS loads can significantly compromise the efficiency of downstream treatment processes, reducing disinfection performance, increasing sludge volumes, and even leading to permit violations if not properly managed. DAF units address this challenge by removing a large proportion of suspended solids at the outset, protecting subsequent treatment stages

DAF systems, in particular, are a highly effective solution for temporary or fluctuating needs when dealing with elevated Total Suspended Solids (TSS) loads over a limited time period. These units can be rented for short- or mid-term use and are designed for easy integration into existing treatment infrastructure. When needed, they can also be tailored to specific site or process requirements, making them a flexible and efficient choice for managing peak loads or temporary process challenges.

At Xylem, we provide advanced solutions designed to enhance energy efficiency and performance in biological treatment processes and to bridge the current blowers in case of failure.

For aerating biological reactors, we offer high-efficiency centrifugal Turbo MAX blowers equipped with directmounted permanent magnet synchronous motors (PMSM). These high-speed motors eliminate mechanical losses by using a direct-coupled impeller on the motor shaft, removing the need for gears, and feature a precisely machined, anodized aluminum alloy impeller to optimize performance. The result is reliable, energy-efficient aeration with minimal maintenance.

We also offer Taron filters, an innovative technology that can either supplement or replace traditional secondary clarifiers. These filters enable wastewater treatment plants to expand treatment capacity to accommodate growing populations and peak flow events, while also helping to meet increasingly stringent discharge limits for solids, nitrogen, and phosphorus. Additionally, Taron filters reduce the overall footprint and cost required to achieve treatment goals, offering greater flexibility and efficiency in plant design and operation.

By integrating advanced disinfection, solid separation technologies like dissolved air flotation (DAF), energyoptimized aeration systems, and modular filtration solutions such as Taron, Xylem delivers comprehensive, sustainable solutions that address the evolving needs of water and wastewater treatment facilities.

Temporary Solutions, Zero Compromise

Unexpected shutdowns or scheduled maintenance can put water treatment performance at risk. For such scenarios, Xylem provides modular, containerised treatment systems for temporary deployment. These plug-and-play units are designed to deliver uninterrupted treatment capability while minimizing site disruption.

Our rental offering includes:

• UV and Ozone disinfection containers for chemical-free pathogen removal

• Blowers for aeration during biological treatment

Whether it’s a planned upgrade or an unplanned emergency, our local teams can mobilize quickly, ensuring your process compliance, operational continuity, and environmental responsibility are protected.

Sustainable Performance with Long-Term Gains

Choosing Xylem’s advanced technologies means investing in long-term efficiency. Modern UV systems now feature low-pressure, high-output lamps with a service life of up to 16,000 hours. Their intelligent controllers can adjust UV intensity in real time, saving up to 20% on energy consumption. With only the lamps and quartz sleeves needing periodic attention, maintenance becomes simpler, cheaper, and greener.

Ozone generators also offer low life-cycle costs. With core units backed by 10+ year warranties, only filters and seals are consumable—resulting in reduced waste and minimized maintenance needs. In systems like cooling towers, Ozone not only disinfects but also prevents fouling and microbial corrosion, maintaining heat exchanger efficiency and minimizing costly downtime.

Driving Compliance and Protecting Ecosystems

With tightening regulations like the Urban Wastewater Directive, businesses are under increasing pressure to reduce environmental impact—particularly in sensitive coastal and inland waters. Xylem’s disinfection solutions help customers meet or exceed these standards without relying on hazardous chemicals that pose safety and handling risks.

This regulatory landscape is also accelerating a shift toward holistic water management—where technology is chosen not just for what it removes, but how it performs throughout its lifecycle. Xylem’s solutions support this shift, providing scalable, future-ready platforms that prioritize performance, compliance, and sustainability in equal measure.

A Greener Path Forward

At Xylem, we understand that water treatment is not just about protecting process performance—it’s about protecting people, ecosystems, and communities. With every deployment of UV and Ozone systems, with each rental unit delivered during a crisis, we help customers move toward a more resilient and sustainable water future.

FNanoScope™: Predicting, Preventing, and Reversing Membrane Fouling

or more than 35 years, WaterSurplus has tirelessly strived to provide creative solutions for challenging problems. We began by transforming surplus water industry inventory into valuable assets. The company grew into a technology innovator, developing groundbreaking systems such as the ImpactRO™ brackish water reverse osmosis system and NanoStack™ membranes. These technologies have reduced membrane fouling, lowered operational costs, and improved sustainability.

Today, we are proud to introduce our latest breakthrough—NanoScope™.

A Technology Breakthrough

NanoScope is a powerful membrane monitoring system and now the latest piece in WaterSurplus’s packaged RO solution, ImpactRO. The system monitors membrane performance at an unprecedented depth—detecting

performance loss well before traditional metrics, such as trending normalized permeate flux. In practice, this means that NanoScope can detect fouling events hours or days before that event alters the system’s overall performance.

Once a fouling event is detected through NanoScope, the WaterSurplus team or the local operator can implement one of ImpactRO’s fouling prevention measures. These interventions can prevent fouling events from escalating to a point where an unplanned cleaning is required. Examples of prevention measures include:

Ian Tonner Vice President of WaterSurplus’s Engineering Division

• Micro-Disruptions – Brief, intermittent bursts of feedwater that disrupt the concentration polarization layer, increasing the crossflow velocity to the tail membranes, flushing scale and foulants to drain while the system remains online.

• Intermittent Variable Recovery (IVR) – Automated modulation of the RO recovery setting to restore hydraulic balance and protect against fouling, even under changing feedwater conditions.

NanoScope achieves this rapid detection by measuring the flux and quality from only a small portion in an array, typically the final, tail element, where deteriorating performance first appears. By isolating and tracking

performance on the most stressed part of an RO system, operators can identify, isolate, and address issues sooner, avoiding costly unplanned shutdowns.

With NanoScope and ImpactRO’s other unique characteristics, users can expect:

• Reduced membrane cleaning frequency

• Lower energy consumption

• Longer membrane life

• Less system downtime

• More consistent water quality

Development Journey

Five years ago, WaterSurplus was awarded a research grant from the U.S. Bureau of Reclamation to pilot advanced RO optimization concepts. In our 150 GPM containerized ImpactRO pilot unit, we tested a wide range of variables—scaling rates, fouling behavior, membrane types, and operational configurations.

As our team investigated the capabilities and combined benefits of our innovations, it became necessary to stress-test the system, purposefully and repeatedly inducing fouling and scaling events. It was clear that we needed to detect exactly when fouling events begin, rather than waiting for traditional performance metrics. It was at this time that our engineering team developed and patented the technology that would become NanoScope.

Initially, beta versions of the technology were included on some ImpactRO systems as a way for WaterSurplus to monitor the performance of the RO. But as the technology was refined, it became clear that the monitor itself was a significant feature. We realized it could be used to guide the ImpactRO’s existing interventions to restore the system’s active membrane surface area.

NanoScope’s launch marks the first time such predictive monitoring and online interventions have been integrated into a commercial RO platform.

Looking Ahead

The introduction of NanoScope is a step forward in our long-term vision: to drive the water industry toward higher efficiency, lower environmental impact, and greater operational resilience, even when treating

challenging waters. By combining intelligent monitoring, advanced membrane technology, and online intervention, we are proving that RO systems can adapt to fouling events in real time and return to the original design parameters—not just respond after the fact.

At WaterSurplus, we will continue to look beyond current capabilities and imagine what is next. The future of high-efficiency water treatment depends on it.

Sidebar: Intelligent Interventions in ImpactRO™

• NanoStack™ Membranes – Engineered with a bioinspired, hydrophilic polymer coating that reduces scale adhesion and repels foulants.

• NanoScope™ Monitoring – Predicts, prevents, and reverses membrane fouling using advanced analytics.

• Feed-Forward Design – Balances flux evenly across all RO stages.

• Membrane Micro-Disruptions – Brief, intermittent bursts of feedwater that create a high cross-flow velocity state to clean membranes during operation.

• Intermittent Variable Recovery (IVR) – Automated recovery modulation to prevent and reverse fouling during fluctuating feed water conditions.

Safeguarding supply: why robust process filters are more critical than ever

Written By | KEITH WICKERT, TECHNICAL MANAGER AT AMAZON FILTERS

Municipal water companies around the world have increasingly high expectations of their suppliers of filtration equipment and solutions. Procurement decisions are shaped by regulatory pressures, environmental goals, cost constraints and the constant need for reliability and innovation. Keith Wickert, Technical Manager at leading process filter manufacturer Amazon Filters, will discuss the latest in technology enhancements when he presents at the WWT Drinking Water Quality Europe event in Amsterdam in November. Here, Keith outlines his key message.

When it comes to technical performance and reliability, our customers in the municipal water supply sector look for proven effectiveness. They want filtration solutions that meet or exceed performance standards for the control of turbidity and removal of contaminants such as manganese and cryptosporidium.

Process filtration must operate reliably over time, with minimal fouling, clogging or degradation, and be scalable so as to handle variable flow rates. It must also be sufficiently future-proof to comply with tightening regulations.

At Amazon Filters, we have made and supplied filters, housings and critical filtration solutions to support the municipal water supply in the UK and Europe for 40 years, with an increasing focus now on customers right across the world.

Among our products is SupaSpun II, an absolute-rated depth filter that has long been on the approved list for use in the UK public water supply under the Drinking Water Inspectorate’s Regulation 31.

Based on flow rates and projections, cartridge filtration involving SupaSpun II helped to filter more than 350 billion litres of water last year, ensuring a safe, clean and

consistent supply to tens of millions of homes and businesses.

In March 2024, after extensive testing, SupaSpun II also gained KTW DVGW certification for safety in the municipal water sector under German regulations set down by the standards body DVGW, the German Technical and Scientific Association for Gas and Water. This is expected to be the springboard for EU-wide approval in the future.

For all our products aimed at the public water supply sector, including SupaSpun II, we have ensured that technical enhancements comply fully with the recasting of the EU Water Directive (DWD) 98/83/EC and its tighter rules on cartridge filtration. The directive revised down the previous indicator level of turbidity at the tap from <1NTU to <0.3NTU. Municipal water filtration systems installed across the UK are already helping suppliers meet this target.

At the same time, we have released sustainable polypropylene versions of SupaSpun II and other flagship products. This is of direct benefit to our customers in the municipal water sector who are keen to see green innovation and a lower carbon footprint among their suppliers.

In the UK this has come about just as the water industry begins to manage assets, deliver services and invest in infrastructure under the latest five-year regulatory cycle, AMP8, running from this year to 2030.

As demand continues to rise and we see further changes in the environment, the challenges involved in maintaining continuous supply will only intensify.

My key message when I present to industry leaders in Amsterdam will be how Amazon Filters can support industry in the drive for continual improvements in the public water supply through technology enhancements and treatment innovation, and the part that robust, sustainable filtration can play in that aim.

Components and equipment with long lifespans that are sustainably made, offer cost-efficiency in operating environments and minimise downtime are fundamental.

My colleague Lisa Astbury, our Head of UK Sales, is an expert in all the critical aspects of industry engagement and offers complementary insight in support of the message.

“The successful management and performance of ‘source-to-tap’ investments over the next five years will be an essential aspect of UK water companies’ response to AMP8,” says Lisa. “The same kinds of challenges are there for the municipal water supply in other countries too, spanning environmental, regulatory, financial and technological factors. Suppliers of technology, equipment and solutions, including filter manufacturers like us, need to demonstrate an evolving mix of value for customers. This includes support for energy and resource efficiency, digital integration, real-time monitoring, ESG credentials and a strong sustainability ethos.”

Breakthrough Technology Delivers Powerful Ferrate Reagent On-site and On-demand

Written By | RICK BACON, CEO, AMS

One of the most powerful known water treatment chemicals is the oxidant ferrate (Fe+6), which has a higher oxidation potential than ozone and almost twice that of chlorine. This potent reagent has been widely documented to effectively address a wide range of the most challenging contaminants faced by the global drinking and wastewater treatment industry (Table 1).

Until now, a ferrate (Na2FeO4) solution has not been commercially available or widely used in treatment processes because it decomposes rapidly and cannot be manufactured, transported, or stored. Now, following the successful development of a proprietary in-situ electrolytic ferrate reagent generation system (SafeGuard™ H2O) by AMS, the commercial use of ferrate is a reality. The SafeGuard H2O system generates a ferrate solution concentrate by electrolysis at the point of use and on demand, producing a high-yield reagent (> 7,000 ppm as iron (VI)).

SafeGuard H2O addresses the inherent problems of

industrial-scale ferrate solution supply, including instability, yield, and concentration, by producing a non-toxic reagent through a simple and cost-effective electrolytic process.

This breakthrough technology requires only three widely available consumables: a sacrificial iron anode, caustic soda and electricity. It is a one-step process in which the electrolyte caustic soda solution is continuously fed into the electrolytic generator, and the outflowing ferrate reagent is dosed into the flow or batch of contaminated water requiring treatment. Because caustic soda is a low-value industrial by-product, its use in the production of a ferrate solution represents the beneficial transformation of an otherwise unwanted chemical into a high-value and safe chemical reagent.

Facilitating the Evaluation of Ferrate: AMS’s Frozen Reagent Solution

To streamline application and research, while eliminating the requirement to produce this reagent at-site for every project, AMS also offers the ferrate solution in frozen form for those wishing to evaluate contaminant-specific

applications (Figure 1). By generating the reagent at its facilities in Sunnyvale, California, and immediately freezing it, the high-purity reagent, which maintains its chemical properties while frozen, can be readily shipped anywhere in the world. Chemical engineers, university researchers, water treatment specialists, and other professionals can conveniently use these frozen samples to evaluate the performance of ferrate for their specific application needs. AMS supports such evaluations with advice on protocols and testing. By providing ferrate in this format, AMS aims to accelerate awareness and adoption of this transformative chemical.

AMS is also making available the opportunity for stakeholders to participate in the open sourcing of results from other users, albeit anonymously, based on application, contaminant, and treatment efficacy.

The development of SafeGuard H2O’s proprietary in-situ ferrate generation system represents a significant advancement in water treatment technology. By enabling the safe, sustainable, and on-demand production of a high-purity ferrate solution, AMS has addressed the traditional challenges of ferrate synthesis, stability, and application. The availability of frozen, stable samples for various testing scenarios further expands the reagent’s accessibility and utility.

The Future of Water: From Myths to Molecular Solutions

Written By | FABIO HÜTHER, CO-FOUNDER AND HEAD OF DEVELOPMENT & RESEARCH, EVODROP AG

Water is life. I learned this painfully as a child while battling cancer, a battle that left me with a lifelong awareness of how vital pure, safe water is to human resilience. Years later, when my godchild in Africa died from cholera caused by contaminated water, grief turned into determination. I realized water is not simply a resource; it is the foundation of health, dignity, and survival. That realization fuels my mission at Evodrop: to develop scientifically validated, patented solutions that deliver safe, bioavailable, and truly life-enhancing water.

The Problems We All Know

Professionals in the water sector know the landscape well:

Contaminants: Thousands of potential pollutants (including microplastics that penetrate the blood–brain barrier, pharmaceutical residues resistant to breakdown, and pesticides and fungicides that remain undisclosed). Current monitoring covers only a fraction of the risks.

Aging infrastructure: Lead, copper, cement, and even uranium can leach into drinking water through outdated or naturally contaminated sources.

False promises: The hype around alkaline water dominated for years, only to be scientifically disproven. Research published after 2012 clarified that the observed health benefits were not due to alkalinity but to dissolved molecular hydrogen (H₂).

The industry cannot afford myths or half measures. What is needed are scientifically rigorous, patented solutions that target contaminants comprehensively, enhance biological water quality, and prove their benefits.

Evodrop’s Patented Solutions: Problem by Problem

At Evodrop, each challenge meets a dedicated, patented solution:

Problem: Incomplete contaminant removal with conventional filters

Our patented solution: Nanoporous adsorber fleece, a highly engineered filtration medium that outperforms activated carbon by selectively binding a broader spectrum of contaminants, including microplastics and

pharmaceutical residues.

Problem: Environmentally harmful chemical descaling

Our patented solution: The world’s only bio-based decalcification system, powered by natural malic acid. This protects appliances, plumbing, and the environment without introducing synthetic chemicals.

Problem: Misunderstood health claims about alkaline water

Our patented solution: Molecular hydrogen (H₂) infusion. Backed by hundreds of peer-reviewed studies, H₂ has documented antioxidant and signaling effects. It supports recovery, reduces oxidative stress, and enhances metabolic resilience. This is the true mechanism behind the health benefits that were once incorrectly attributed to so-called alkalinity.

Problem: Low cellular absorption and poor bioavailability

Our patented solution: Nanoclustered water domains, enhanced through turbulence and structuring processes, optionally combined with molecular hydrogen. This increases cellular uptake and metabolic bioavailability, supporting hydration and physiological function at the most fundamental biological level.

Redefining Good Water

Truly good water is defined not by marketing slogans but

by measurable scientific standards. At Evodrop, we define it by four interlinked criteria:

• Free of harmful contaminants

• Structurally optimized at the nanocluster level for improved bioavailability

• Capable of transporting charge and solutes effectively

• Enhanced with molecular hydrogen for measurable therapeutic benefit

This multidimensional framework (chemical, physical, and biological) represents the new frontier of water quality.

From Evidence to Responsibility

Evodrop collaborates with leading universities and accredited laboratories to test and validate our systems. Every solution we bring to market is backed by patents and peer-reviewed data. Our philosophy is simple: publish results, not slogans.

As the global water crisis intensifies, the choice becomes clear: either rely on outdated myths and incomplete technologies or embrace solutions that unite scientific rigor with proven innovation.

At Evodrop, we choose the latter, ensuring that the water of tomorrow is not only safe but truly life-enhancing, drop by drop.

Maximizing Cycles of Concentration:

The Role of Water Quality in

Tower Efficiency

Written By | PAUL SHARPE, KURITA INDUSTRY CONSULTANT

According to the United States Environmental Protection Agency, cooling towers account for over 50% of water consumption at industrial facilities. This makes cooling towers the prime target for sustainability improvements. If a facility manager does not want to reduce efficiency or risk assets, then they should consider tower makeup water quality and how it affects their systems and implement innovative solutions for optimized water management.

Cooling towers are vital for maintaining process temperatures, protecting equipment, and ensuring operational continuity. Yet the performance and longevity of these systems depend heavily on an underestimated factor: the quality of the water entering the system.

Cooling

Utilizing Pre-Treatment for Water Quality

Industrial facilities often deal with varied water conditions, seasonal changes, and process contaminants, making consistent water quality management a challenge. To ensure optimal water quality, facilities may need to implement pre-treatment before boilers, cooling towers, and heat exchange processes.

Common pre-treatment methods:

• Filtration removes suspended solids and particulates

• Best for facilities using surface water, well water, or recycled water and/or with high particulate loads.

• Softening reduces hardness (calcium, magnesium ions) to prevent scale.

• Best for facilities with hard water sources and in heavy industries, such as power plants, chemical manufacturing, and metal processing

• Reverse osmosis (RO) removes dissolved salts and organics.

• Best for facilities aiming for high purity water and increased cycles of concentration, especially in the semiconductor, pharmaceutical, and food and beverage industries

Paul Sharpe Kurita Industry Consultant

In combination with the previous methods, chemical additions work in all facilities with varied water quality to manage corrosion, scale, and microbiological growth. The choice of pre-treatment depends on the source water and the specific system requirements.

However, by increasing the quality of the water being used for heat transfer, a facility can maximize cycles of concentration (COC) in cooling towers and boilers without compromising system integrity or environmental compliance. In fact, increasing cooling tower COC from three to six can reduce makeup water consumption by 20% and blowdown volume by 50% (United States Energy Department).

Increasing Cycles of

Concentration

in Cooling Towers

Cooling towers operate by evaporating water to remove heat, and this process concentrates dissolved minerals and impurities in the remaining water. If the incoming water is of poor quality or high in dissolved minerals, it promotes the formation of scale, corrosion, and biofouling, potentially reducing heat transfer efficiency and increasing energy consumption. This can lead to expensive downtime and increased utility costs.

Poor water quality forces operators to lower COC to discharge water from the system and decrease impurities, raising costs and water consumption. With adequate pre-treatment prior to utility or process water, assets can not only be protected but reduce stress on the environment through water and chemical savings.

treatment provider is key to developing a water reduction plan with the common goal of asset protection through well managed chemical use.

Working with a Long-Term Partner

As industries face increasing pressure to improve sustainability, facilities need a long-term water treatment partner who understands and delivers a solution that evolves with any challenge. In regard to increasing COC – and perhaps the addition of innovative chemicals and state-of-the-art equipment – attentive service offers an environmentally friendly holistic approach.

Sites dedicated to sustainability should focus on water treatment solutions that reduce water and fuel consumption, ensuring a minimized environmental impact. As an example, Kurita’s bio-based cooling water solution Tower NG can replace traditional phosphorusbased chemicals. Going a step further, facilities can further research their partners’ value chain emissions – also known as Scope 3 – and overall sustainability initiatives. In this context, water quality is not just a technical concern but a cornerstone of responsible water management.

Improving water quality before the cooling tower is a gateway to smarter, more sustainable operations. By investing in pre-treatment strategies, understanding the relationship between water chemistry and cycles of concentration, and utilizing knowledgeable and sustainable companies, a facility can reduce water consumption, lower chemical use, and extend equipment life.

Just like pre-treatment has methods to maintain water quality, utility water and process water have solutions. As an example, it is possible to have specific chemical dosing with scale and corrosion inhibitors, biocides, and dispersants that can increase COC by extending the scale inhibition characteristics of poor quality water. Any chemical treatment should be monitored to ensure operational efficiency, asset protection, and ecological preservation.

Partnering with a competent, established water

Desalination as a Pathway foR Peace and Stability: An Interview with Shannon McCarthy

Written By | MARTYN SHUTTLEWORTH

Set against a changing climate, prolonged droughts, and overextraction, political disputes over access to water resources are shaping international relations. Clean water is crucial for society, economies, and food production so, when countries face water shortages, tensions rise and governments start to accuse each other of taking more than their fair share from shared rivers, lakes, and aquifers.

However, although dwindling water resources are a huge problem, especially in areas with high population growth, political instability is not the inevitable outcome. Desalination, already used extensively in MENA and other parts of the world, offers an alternative source that can defuse conflicts and provide agriculture, industry, and people with the water they need.

To learn more about how desalination can help prevent conflicts, we talked to Shannon McCarthy, the Secretary General/Executive Director of the International Desalination and Reuse Association. With a deep knowledge of the subject and direct experience of how it

Shannon McCarthy Secretary General/Executive Director of the International Desalination and Reuse Association

can reduce friction, she explains how desalination can help solve the global water shortage and discusses ongoing improvements to the technology. Most importantly, Shannon reveals how desalination can promote cooperation and become a catalyst for peace.

Can you share your background and passion for desalination? What led you to pursue it as a career?

My academic background in international relations and public policy laid the foundation for my belief that technical solutions to support increased amounts of clean water—such as through desalination—can build resilience, strengthen security, improve quality of life, and even bridge divides between communities.

It was through my work at the Middle East Desalination Research Center in Oman, a special project born from the Middle East Peace Process, that I first entered the field of desalination. Serving as Deputy Center Director, I witnessed how bringing experts from across borders together around a shared water challenge could ease tensions and build trust. That experience shaped my conviction that desalination is not just about technology; it can also be a tool for peace.

For over two decades, I have dedicated my career to advancing non-conventional water resources as solutions to scarcity, working across the Middle East and North Africa, including the Gulf Cooperation Council, Jordan, Israel, and the Palestinian Authority. Repeatedly, I have seen how water scarcity can stall social and economic development and even fuel conflict—while investments in desalination and other non-conventional water solutions can open the door to opportunity, cooperation, and hope.

What is IDRA, and what role does it play in promoting desalination?

The International Desalination and Reuse Association is a global nonprofit organization founded in 1973 and now operates with members in over 60 countries. IDRA holds consultative status at the United Nations ECOSOC, FAO (via WASAG), and UNFCCC. We bring together policymakers, utilities, researchers, private sector experts, financiers, and civil society. Our work includes convening international technical conferences and forums, offering scholarships, facilitating public-private partnerships, influencing policy frameworks, and championing education and capacity building. We are a global convener and knowledge hub advancing sustainable desalination and water reuse solutions.

Why is desalination critical to solving

global water challenges? What are its main benefits?

Desalination transforms seawater and brackish water into a dependable supply of freshwater, providing security in regions where conventional sources are scarce or over-stressed. Its greatest benefit is reliability—unaffected by rainfall or climate variability—making it vital for cities, agriculture, industry, energy production, and tourism.

Technological innovation has dramatically lowered costs and energy demands, and when paired with renewable power and water reuse, desalination becomes a cornerstone of sustainable, circular water systems. It not only diversifies water portfolios but also reduces stress on rivers and aquifers, while helping communities adapt to the increasing challenges of climate change.

What are the hidden challenges of desalination? How is IDRA promoting environmental and social sustainability?

Desalination delivers tremendous benefits, but it also brings challenges that must be addressed with care. Critics often point to its energy footprint, potential brine impacts on marine ecosystems, and the risk that high costs or limited local capacity may exclude rural or underserved communities.

At IDRA, our global membership actively tackles these issues through integrated, sustainable solutions. We champion pairing desalination with renewable energy and water reuse, while advancing brine valorization—such as mineral recovery, metals extraction, and zero liquid discharge. Our working groups and task forces develop guidelines for energy efficiency and environmental responsibility, and we collaborate with utilities and regulators to embed social impact assessments, circular design principles, and local procurement into project development.

This collective effort ensures desalination evolves not only as a technical solution but as a socially inclusive and environmentally responsible cornerstone of water resilience.

What emerging technologies will shape the future of desalination?

The coming decade promises transformative advances in desalination. Low-pressure membrane techniques,

Continued on page 54

forward osmosis, and graphene-enhanced filters are maturing rapidly, delivering higher efficiency and lower energy requirements. Sub-sea and zero liquid discharge systems are becoming commercially viable, addressing environmental concerns around brine disposal.

Digital technologies—including artificial intelligence, machine learning, and digital twins—are enabling smarter plant operations, predictive maintenance, real-time optimization, and reduced operational costs. Brine valorization is unlocking new opportunities, allowing the recovery of critical materials such as lithium, magnesium, and gypsum. Hybrid systems that integrate solar power, desalination, and water reuse are enabling modular, decentralized solutions, ideal for remote communities or rapidly growing urban centers.

Together, these innovations position desalination as a cornerstone of resilient, sustainable water systems and a growing global market projected to reach multi-billiondollar scale, responding to increasing demand and climate pressures.

What policies have impressed you the most? What further policies should governments and international bodies adopt?

Singapore’s Water Master Plan stands as a global benchmark, integrating desalination, reclaimed water, catchment management, and clear regulatory frameworks into a cohesive strategy. The European Union's emerging circular water economy regulations and reuse standards set important precedents for sustainable urban water management. In the United States, the EPA has recently finalized the first-ever National Primary Drinking Water Regulation for PFAS, establishing enforceable Maximum Contaminant Levels. Additionally, California has implemented a comprehensive Direct Potable Reuse (DPR) regulatory framework, allowing treated wastewater to safely re-enter the drinking water supply, setting a precedent for scalable urban water recycling.

In the Middle East and North Africa, Saudi Arabia’s National Water Strategy emphasizes large-scale desalination paired with renewable energy and water reuse to ensure municipal, industrial, and agricultural security. The United Arab Emirates has advanced integrated water resource management combining desalination, reuse, and smart infrastructure. In Jordan, the Amman Conveyance Project demonstrates innovative approaches to secure urban water and relieve stress on freshwater sources. Morocco, Tunisia, and Algeria are scaling renewable-powered desalination and reuse projects to meet urban and agricultural water needs and enhance

climate resilience. In Brazil, inland renewable-powered desalination initiatives are being implemented to combat desertification in semi-arid regions, providing reliable water for local communities and agriculture while restoring degraded lands. South Africa has integrated desalination and water recycling to address persistent water scarcity in urban and rural areas. In Australia, large-scale desalination plants in Perth and Sydney, combined with water recycling and stormwater harvesting, provide resilient urban water supplies while reducing pressure on traditional freshwater sources.

The World Bank is actively supporting countries worldwide to scale desalination and water reuse solutions, providing technical assistance, funding, and policy guidance to accelerate sustainable water infrastructure development, particularly in water-stressed regions. These initiatives emphasize circular water management, integration with renewable energy, and inclusive governance to strengthen resilience against climate variability.

These measures reflect a broader focus on responsible water stewardship behaviors, including efficient water use, monitoring and reporting, pollution prevention, and public engagement in water sustainability. Despite these successes, there is a pressing need for more cross-border governance, especially for shared seas, transboundary

aquifers, and international river basins. Effective policies should promote data sharing, joint R&D investment, environmental safeguards, transparent tariff structures, social inclusivity, and regulated pilot testing of emerging technologies. Governments and international bodies should also incentivize public-private partnerships and encourage water stewardship behaviors across industries and communities.

You focus on public private academic collaboration. Why is that important? Do you have a strong example?

Collaboration across sectors is essential to scaling water solutions, building workforce capacity, and ensuring that innovations are relevant to local needs. IDRA’s Fellowship, scholarship, academy, and Young Leaders Program have supported emerging water professionals from across the globe through mentoring, internships, and leadership development. These programs have partnered with leading utilities, research institutes, and agencies such as SWCC, PUB, the U.S. Bureau of Reclamation, and Water Corporation Australia to provide hands-on training and global exposure. Through its participation in with the

United Nations ECOSOC, and UNFCCC, IDRA contributes to international efforts to strengthen education, training, and capacity-building in desalination and water reuse.

A recurring theme in your work is peace. How can desalination help in conflict prevention?

Water scarcity has often caused tension, especially when shared across regions or states. However, desalination and reuse provide a reliable and independent water source, reducing pressure on shared freshwater resources and helping prevent disputes. Supplementing water supply allows communities and countries to manage scarce resources collaboratively rather than competitively.

By integrating desalination with renewable energy and water reuse, countries can enhance water security, reduce conflict risk, and promote sustainable cooperation, transforming water from a potential source of tension into a pathway for peace and stability.
