Connecting the Biosolids Community New talent and resources affirm WEF’s commitment to sustainable biosolids management Justin Jacques Water resource recovery professionals have long understood that when processed correctly, fertilizers made by repurposing wastewater biosolids can often represent a safer, cheaper, and more sustainable soil amendment compared to manure or chemical-based fertilizers. While biosolids reuse in the United States has become more common in recent decades, its adoption has been sluggish because of inconsistent regulatory guidelines, gaps in research, and the social stigma of recycling human waste. The Water Environment Federation (WEF) is taking several new steps to help overcome these obstacles. It recently released a new communications toolkit to help utilities and biosolids managers build support for biosolids recycling using simple, science-backed messaging. The organization also established a new staff position, hiring Maile Lono-Batura, former executive director of Northwest Biosolids in Gig Harbor, Wash., as its first director of sustainable biosolids programs. “Biosolids is a central product of the wastewater treatment process, a vital part of

resource recovery and the circular economy, and beneficial for communities in many ways,” said Lynn Broaddus, WEF president. “We are increasing our investment in biosolids programs and are thrilled to add Maile’s expertise and experience to our team.”

A Unified Voice With more than 20 years of experience leading a multistate biosolids association, LonoBatura is uniquely suited for her new role, which will involve unifying biosolids recycling practices and regulations that vary by region and state. In a February 16 “Words on Water” podcast interview, Lono-Batura described her goal to create a “collective platform” for biosolids research, advocacy, and knowledge-sharing at the national level. Much of her work will center on sharing resources among biosolids-management groups to reduce redundancies and amplify messaging, she said. “For those of us in the field of biosolids, we know how important it is to have a unified voice around biosolids so that we’re all singing from the same song sheet,” Lono-Batura said. “It’s going to be a challenge, for sure, but it’s such a worthy challenge to me.” The new WEF Biosolids Communications

Toolkit, accessible at bit.ly/WEF-biosolids, will help jumpstart Lono-Batura’s work by providing customizable bill inserts, fact sheets, social media infographics, and other materials that convey key messages about biosolids in simple, accessible terms. Each resource available in the free toolkit works from cited, peer-reviewed sources and aims to reach different stakeholder groups, including those both inside and outside the wastewater sector. For example, some resources cover strategies for managing media coverage of biosolids programs, while others tout the benefits of biosolids-based fertilizers for farmers. “We ‘geek out,’ and that’s not a bad thing within our circle,” Lono-Batura said, “but we lose people pretty quickly if we cannot relay the importance of what the research has found, whether it be favorable or unfavorable.” Although much of WEF’s existing activity in sustainable biosolids has been technical in nature, Lono-Batura’s new role indicates a growing focus on the social and logistical aspects of the biosolids challenge. She will not only work alongside biosolids professionals among WEF’s membership, but also with regulators, environmentalists, the media, and others. “There is a whole team of people, not just within WEF, but within and beyond the biosolids community that we can be aligning with—that part is what really excites me,” Lono-Batura said. “We need to speak beyond our sector and connect with people we normally don’t to see what common ground we have and how we can join forces on soil building, climate change, and producer responsibility.”

The new director position and communications toolkit promise to advance national coordination on biosolids recycling, but they are only the latest actions. In November 2019, for example, WEF invited leading biosolids experts from across North America to its headquarters in Alexandria, Va., for a strategic conversation that identified ways to improve biosolids programs and better promote their adoption. Among other recommendations, meeting attendees described needs for better risk assessment methods for contaminants of emerging concern, new training and certification programs, and more-robust communication among producers, farmers, and researchers.

Continued from page 4 Experts also called for an update to federal government guidance on biosolids use, as most states currently implement their own biosolids regulations. The U.S. Environmental Protection Agency (EPA) Part 503 Rule, established in 1993, remains the only federal regulation governing land application of biosolids. Despite advancements in treatment technology that result in cleaner, safer, and more-viable biosolids, the Part 503 Rule has never undergone a substantial update.

Duval County Veterans Memorial Wall: A Tribute to Fallen War Heroes The City of Jacksonville is home to the nation’s second largest veterans memorial wall, second only to the Vietnam Veterans Memorial In Washington, D.C. The quarter-million dollar monument was dedicated in November 1995 and serves as a tribute to more than 1,600 Jacksonville-area American war heroes. The outdoor memorial is promoted as the largest of its kind and the only wall that honors veterans from all six service branches (Army, Navy, Marines, Air Force, Coast Guard, and Merchant Marine). The 65-foot-long black granite monument contains the names of servicemen and women from World War I through the War on Terror. In front of the wall stands a torch with an eternal flame.

The wall is outside of the Jacksonville Veterans Memorial Arena. The original Jacksonville Coliseum that was on the site was imploded on June 26, 2003, and replaced with the $130 million arena building. Extreme care was taken not to damage the black granite memorial wall located just 8 feet from the east wall of the building. After the debris was cleared, a 2-acre walking park was added to the area around the memorial.

Dedication from President George H.W. Bush.

The Memorial Wall.

10 November 2021 • Florida Water Resources Journal

An additional 2,500-pound base and 5,000-pound panel were added to the wall area in 2005 to provide space for those killed in Iraq and Afghanistan, but it became clear that the single panel would not be sufficient, based on the course of the war, so one more was added prior to the Memorial Day ceremony in 2010, the 15th anniversary of the monument. Ten names were added in 2010, four of which are on the most recent panel, which brings the total number to over 1,600. Four more names were added in 2014. The wall was rededicated on its 20-year anniversary in November 2015. Each year, on Memorial Day, thousands of Gold Star families, veterans, local military leadership, elected officials, and citizens honor the fallen heroes whose names are permanently inscribed on the wall. The names of those who

Governor’s and Mayor’s Challenges to Prevent Suicide Among Service Members, Veterans, and Their Families The Substance Abuse and Mental Health Administration (SAMHSA) has partnered with the United States Department of Veterans Affairs (VA) to bring the program, Governor’s and Mayor’s Challenges to Prevent Suicide Among Service Members, Veterans, and Their Families, to states, cities, and communities across the United States. Thirty-five states are taking part in the challenge and are working to develop and implement statewide suicide prevention best practices for service members, veterans, and their families (SMVF), using a public-health approach. Twenty-two communities were originally engaged as part of the challenge. Currently, 19 challenge teams are actively participating; seventeen of the communities are within participating Governor’s Challenge states and one was added in 2021. The SAMHSA’s SMVF

TA (Technical Assistance) Center is providing technical assistance for both of these initiatives.

S

Challenge Objectives The objectives of the program include the following: S Convene a state (Governor’s Challenge) or city/community (Mayor’s Challenge) interagency military and civilian team of leaders to develop an implementation plan to prevent suicide among SMVF that will advance the VA’s “National Strategy for Preventing Veteran Suicide,” and incorporate evidence-based strategies from the Centers for Disease Control and Prevention (CDC) program, “Preventing Suicide: A Technical Package of Policy, Programs, and Practices.” S Implement promising, best, and evidence-

based practices to prevent and reduce suicide at the national level. Engage with city, county, and state stakeholders to enhance and align local and statewide suicide prevention efforts. Understand the issues surrounding suicide prevention for SMVF. Increase knowledge about the challenges and lessons learned in implementing best policies and practices by using state-to-state and community-to-community sharing. Employ promising, best, and evidencebased practices to prevent and reduce suicide at the local level. Define and measure success, including defining assignments, deadlines, and measurable outcomes to be reported.

Participating Governor’s Challenge States The following states are currently participating in the Governor’s Challenge:

Team Composition Governors, mayors, or county commissioners appoint team leaders to serve as the point of contact and coordinator for the challenge process. Team leaders then receive technical assistance to design a strategic interagency team composed of individuals with the ability and authority to advance and implement statewide policy and practice changes. Teams are encouraged to include both military and civilian representatives as described. Perhaps most critically, teams are encouraged to include suicide prevention coordinators representing the state public/behavioral health agency, VA, and National Guard. S S enior-level representatives/policy makers are included from the following: • G overnor’s/mayor’s/commissioner’s office representative • G overnor’s Challenge • Suicide prevention coordinators from state, VA, and National Guard • State agencies responsible for mental health, substance use, and VA • National Guard • Reserve Affairs • Medicaid and/or Social Security Administration • VA’s Veterans Integrated Service Network (VISN) serving the state • Veterans Experience Office • M ayor’s Challenge • MyVA community veterans engagement board • VA local suicide prevention coordinator • National Guard suicide prevention coordinator • State public health suicide prevention coordinator • State SMVF team leader

S A service member or veteran and/or a family member of a service member or veteran Teams are also asked to consider including other members, such as: S SMVF peer support leaders S Veterans service organizations S Military and veteran caregivers S State and/or local legislators S State/local training leadership S Leadership from federally recognized tribes S Private-sector leadership from innovative programs serving the needs of SMVF, such as community mental health clinics, community service boards, and crisis service systems S Individuals with expertise in labor/ employment, criminal justice, housing/ homelessness, primary care, substance use and mental health services (including suicide prevention), and child/family issues S Individuals representing advocacy groups, social/public health organizations or coalitions, and the faith-based community This cross section of military and civilian agencies allows the teams to effectively plan for increased coordination of efforts and integration of SMVF into their existing state/local suicide prevention plans. Creating a representative team is a critical phase of the work as it builds collaborative working relationships across sectors that are too often isolated. This process also allows for initiatives to be championed, coordinated, and disseminated across many sectors.

Framework for Planning: Ensuring a Comprehensive Approach The VA program, “National Strategy for Preventing Veteran Suicide,” provides a framework for integrating and coordinating suicide prevention activities across multiple sectors. The Governor’s and Mayor’s Challenges advance the principles of the national strategy by facilitating policy-topractice implementation plans. These plans will serve as instruments of change, providing a best-

Healthy and Empowered Veterans, Families, and Communities 2. Clinical and Community Preventive Services 3. Treatment and Support Services 4. Surveillance, Research, and Evaluation In addition, the CDC program, “Preventing Suicide: A Technical Package of Policy, Programs, and Practices,” is used to help teams incorporate evidence-based strategies and best practices into their planning. The Governor’s Challenge is an intensive process that takes each state team through the stages of both a policy academy model and an implementation academy model. These models offer a proven process and foundation for bringing policy-to-practice change in state behavioral health care systems.

Key Efforts and Accomplishments Key accomplishments for the Governor’s and Mayor’s Challenge teams include the following: S Reducing suicide among service members, veterans, and their families. S Increasing access to services and support. S Expanding statewide capacity to engage SMVF in public and private services. S Enhancing provider and SMVF peer practices. S Forming cross-system military and civilian consensus on priorities and plans for action. S Identifying critical data elements to measure impact and quality of care. S Strengthening the continuum of care. S Transferring knowledge on evidence-based practices, policies, and strategies that are effective across teams.

Christopher I. Moss.

Marta Madigan and Jay Madigan Celebrating National Veterans and Military Families Month, we sat down with Christopher I. Moss, 39, whose family members served in the military fighting in every war since the Revolutionary War. Before settling in Florida, Moss traveled the world, from New Jersey to Germany, Iraq, Afghanistan, and 20 other countries. Water meandered through each stop on his path, which began in Paterson, N.J., famous for its roaring Great Falls of the Passaic River. After joining the military in 2000, he became an Army water treatment specialist conducting water operations in Europe and Asia. Moss transitioned to his civilian career in water in 2016, the same year he retired from the Army. This year, he received a bachelor’s degree in water resources management from Florida Gateway College. On November 30, he will present his first paper, “Turn the Tide: Veterans and the Future of Water," at the FSAWWA Fall Conference in Orlando.

Meet Christopher Isaiah Moss: Operations Group Shift Lead at Tampa Bay Water, Iraq and Afghanistan War Veteran, and Recipient of 2021 A.P. Black Award You sit in front of two large computer screens. Is all of your work computerized? As the operations lead the bulk of my daily duties requires me work on the computer. Ordering chemicals, monitoring supervisory control and data acquisition (SCADA), completing daily reports, purchasing equipment, supervising operators, checking water quality, approving payments to vendors—the list goes on. Plus, every operator does some type of manual labor. Some days, it can be light; other days are heavier. Let’s go back in time. You are from Paterson, New Jersey. Tell us about your hometown. Growing up in Paterson, I learned that my city was known for a lot of history. Paterson is the birthplace of the Industrial Revolution here

in the United States, promoted by Alexander Hamilton. His use of the Great Falls, one of the largest waterfalls in the country, is why they called Patterson “Silk City.” It’s also home to the boxer Rubin “Hurricane” Carter. In short, there is a lot of water and history in this town. When did your adventure with water begin, professionally? My water career began when I received orders to change my profession in the Army and to report to training in Fort Lee, Virginia, in 2004. A year later, I was in Iraq for a 12-month tour, then again in 2008 to 2009. Just a few months after I returned from Iraq, I went to Afghanistan. Germany was my home station for 12 years of my military career. Continued on page 16

Marta and Jay: You wear a cuff bracelet on your left wrist. Is there a story behind it? Christopher: I wear this band to honor one of my sisters in arms, Staff Sgt. LaQuita Shree Robinson, who passed away while in service. She was also a water treatment operator. Throughout my time in the service, I have lost several brothers and sisters. I try every day to provide the best quality water to honor them. You are a water operator. Where do you work? I have been employed at Tampa Bay Water since 2018. I have been an operations group shift lead there since October 2020.

Water Falls By Jim Jarmusch, from his 2016 movie “Paterson.”

Chris with his wife, Monica, and daughter, Rosa.

Continued from page 15 You were an Army water treatment specialist working alongside and training soldiers from other countries. What did you learn in the Army and how did it help you to transition to civilian life? I have conducted water operations in Germany, Poland, Iraq, and Afghanistan. The Army gave me many skills, including team building, conflict resolution, personnel management, ways on improvising to complete a task, and leadership. I learned how to successfully multitask. Are there many veteran operators? I have worked with several operators who are veterans in our industry. I would like to see more veterans working in water in the future. What does it take to transition from an Army water operator to a civilian water operator? The path of transition is not a direct route. People will generally consider military experience; however, there are specific requirements for each state certification. To become a licensed operator, 2080 hours of contact time or work experience are required. There is no policy yet in place in Florida that will help veterans with this process. As an American Water Works Association (AWWA) veteran liaison for the Tampa Bay area, I am working together with a team from every Florida Section AWWA region in the state to move forward with

an initiative that will bring veterans and hiring managers on the same page.

a vet reading this, please show up. Let’s fill that room. You too can help tell our story.

Has anything changed in Tampa Bay Water since COVID-19? We adapted quickly to COVID changes. As a result, we were able to keep supplying water to our valued customers. One change was to keep social distancing.

You have a 3-year-old daughter. What can you do to make sure she has an abundance of clean water when she grows up? Her name is Rosa or, as I like to call her, Lady Moss. This is one of the reasons I have elected to pursue a master’s degree in water resources policy and management at East Central University. Throughout the country there is a challenge in sustaining water and making sure we will be able to meet future water demands. I hope to contribute to improving water efficiency and quality for the future.

Thinking about the future, how can we protect utilities from hacking? Operation security, or OPSSEC, which is the military term, is crucial to the water industry. With the innovation of technology, preventing hacking is very important to providing safe drinking water to protect public health. I believe a closer partnership with information technology (IT) departments will help prevent hacking, as IT is no longer just the division that fixes computer issues and resets your password. It’s a critical part of how we defend against terrorist attacks. Educating those in the water industry of this will help prevent hacking; not being complacent is another way. Congratulations on receiving the 2021 A.P. Black Award in the water treatment operator category. What’s next? The FSAWWA Fall Conference. On November 30, at 9:40 a.m., I will present a paper on veterans and the future of water. It will outline how the experience of a veteran’s return to civilian life can both benefit from and serve the urgent needs of the water industry. If you are

Solar Farms, Power Stations, and Water Treatment Plants: Attractions Instead of Eyesores Margaret Birney Vickery Amid the economic and social fallout of the COVID-19 pandemic, many people see the process of restarting society as a chance to do things differently. Some organizations are calling for big investments in infrastructure, both to generate jobs and to promote green economic growth. Projects that sound worthy in the abstract can meet stiff resistance when it’s time to break ground locally. For example, in 2012 I served on a committee tasked with choosing an energy provider to build a solar farm on an old landfill in the town of Amherst, Mass. Neighbors, who were not consulted, fought to preserve a bucolic meadow that had grown up on the landfill site. After several lawsuits, the project died an unhappy death. This debacle got me thinking. As an architectural historian, I knew that Americans had not always been so disconnected from facilities that produced necessities like food, energy, and clean water. My new book, “Landscape and Infrastructure: Re-Imagining the Pastoral Paradigm for the 21st Century,” explores how Western views of the systems that sustain society have evolved. It also highlights contemporary projects that successfully marry infrastructure and community into places where people want to be.

20 November 2021 • Florida Water Resources Journal

Art Objects and Tourist Attractions In European landscape paintings from the 17th and 18th centuries, such as Jacob van Ruisdael’s Dutch landscapes, windmills compete with church spires for prominence on the skyline. This wasn’t just an aesthetic choice: painters focused on windmills because they generated wealth and prosperity. Classic English landscape gardens include a feature called a ha-ha, which is a grassy trench running across a lawn and reinforced by a sunken wall that was invisible from the main house. This created a view of what looked like unbroken lawn, grazed by sheep and cattle— key sources of wealth and prosperity—while separating visitors from the animals and their waste. In the 19th and 20th centuries a handful


of architects and artists wrangled with weaving infrastructure and nature together. Frederick Graff ’s 1823 Fairmount Water Works protected Philadelphia’s water supply and drew hordes of visitors to admire its NeoPalladian architecture and landscape park along the Schuylkill River. In the 1930s Frank Lloyd Wright envisioned a utopian community called Broadacre City, which was his Depressionera answer to urban planning. This project, which was never built, wove together gardens, industry, and residences into what he called a Usonian society—one that offered Americans deeper connections with nature and productivity.

Going Industrial Yet as societies industrialized, artists and landscape architects began to downplay or separate industry and infrastructure from their views of nature. People came to understand nature as something unspoiled and separate from modern communities—a view that still dominates today. As cities and suburbs expanded in the 19th and 20th centuries, so did power stations, water treatment plants, and wastewater facilities. Increasingly, these structures were built on the industrial fringes of metropolitan areas, out of sight and out of mind. Often they were located in underserved communities that lacked the political clout to object. Even renewable energy systems, for all of their green cachet, often perpetuate this destructive tradition. Many solar farms across the United States are lifeless slabs encircled by chain link fences, taking up land and habitat. For most of us, the idea that infrastructure can be inviting and aesthetic seems contradictory.

Productive and Attractive What’s the alternative? In my book I highlight recent infrastructure projects with creative teams that included artists, architects, or landscape architects, and invited community input. These facilities don’t just generate electricity or process waste; they also offer recreation and education, and connect visitors to the sources of their energy and drinking water. The water filtration plant in Hampden, Conn., completed in 2005, is one such ecological and aesthetic asset. The structure, which resembles an inverted silver teardrop, emerges from a landscape carefully designed to mimic the filtering processes that happen within the building.

by green plantings that spread seeds across the surrounding landscape. Waste-to-energy plants are highly unpopular in many places, but developers built a new apartment complex near Amager Bakke to take advantage of the recreational opportunities it offers. The Solrøgård Energy, Climate, and Environmental Park, opened in 2019 in Hillerød, Denmark, is home to a recycling center, geothermal energy system, and stateof-the-art wastewater treatment plant. The plant features two buildings, bifurcated by rainwater gardens and flowering trees, tucked within the landscape. Paths lead over their grassy roofs, and large windows offer views of the treatment processes taking place inside. All of these facilities involve the surrounding community, educate the public, and include nature and the landscape. Such creative approaches could have avoided the bitter dispute Amherst experienced in 2012. Projects like these demonstrate that infrastructure can do more than provide energy and water—it can also create aesthetically welcoming spaces for society. As U.S. leaders consider how to restart the economy, I believe they should consider investing in projects that are not only productive, but enhance and revitalize the communities around them.

FSAWWA SPEAKING OUT

Everyone Has Challenges With Water Fred Bloetscher, P.E., Ph.D. Chair, FSAWWA

H

appy November! The FSAWWA 2021 Fall Conference will be held at the end of the month, and we are planning to be live! Vendor booths and tabletops sold out in September and a full lineup of technical sessions is planned for Monday through Wednesday morning. The conference will have COVID-19 protocols in place because we just can’t shake the ‘vid. It’s part of the “new normal,” which is our conference theme for this year.

What’s the New Normal for Society? So, let’s talk about what the new normal means. Let’s start with the economy and work our way to those looming threats we may have to deal with in the coming year. I will use COVID as the start of the new normal, but I doubt it will be the entire answer. Those of you who have read my blogs, or my infrastructure management book, know that I believe that those in our industry need to understand how the economy works, and how local and national trends impact our livelihood, as we saw after the financial system meltdown in 2008. Our revenues and expenditures were impacted, capital projects got delayed, deferred maintenance needs increased (and are still not resolved), new building construction stopped, growth halted (and contraction set in), and people lost jobs. To make matters worse, our water and sewer funds became the “solution” for lost tax revenues.

Economic disruption on the national (and world) stage impacts what we do, yet we are expected to keep on doing it (i.e., provide safe water and wastewater services to our customers). We also had elected officials trying to “help” residents by lowering water rates, which further eroded needed revenues. Some utilities were still in recovery mode after 2008—trying to get the general fund out of the utility (and maybe pay it back!) when 2020 hit. A new economic challenge was presented by COVID. In many states the economy shut down and schools closed in an attempt to slow the spread of the virus, while we endeavored to develop vaccines and figure out the best way to address those who became critically ill. There were lessons learned during the flu epidemic in 1918 and subsequent pandemics that were mostly controlled, like Ebola and H1N1, through masks, social distancing, rapid vaccine production, and keeping kids home from school. When COVID hit, many changes happened: S Restaurants moved from in-room dining to takeout, so they no longer needed wait staff and dishwashers. S Online shopping became the norm for many people and retail service staff was not retained. S Technology meant there was no need to travel for so many meetings. We realized that travel creates a huge amount of unproductive time, keeping us from getting things done, but airlines, hotels, in-person restaurants, bars, and other services withered due to lack of business traveling. S Whole industries, like banking, engineering, legal, accounting, and similar professions, were done remotely, which means you don’t need offices or the office staff. S Availability of people increased as a result of changes in cellphone and online meeting patterns, which meant, in some cases, productivity soared, while in other cases

people could not escape the interruptions to be productive. S Remote learning for children became common, which altered work patterns and the need for accommodations for parents. S H ome offices were built and houses were fixed up, so construction costs increased due to competition for products and supply-chain challenges. The upside to all of this is that many companies stayed in business and many people kept on working, but there was a downside. Many of the support-staff positions may never return—many stores in retail malls are vacant, restaurants have fewer seats, business travel may remain depressed, and childcare needs may prevent workers from returning to their old jobs. Many of these lost jobs are lower-wage positions, compounding the economic challenges for many. This new age of uncertainty will fundamentally change some communities, creating a need to retrain workers to do new jobs—but what are the new jobs? For those jobs that did return, workers are sending a message that they will go back to work when they feel safe and better-compensated. Kossek and Perrigino (2016) identified a series of job-security challenges affecting many workers: S The rise of job insecurity and precarious work. S The intensification of work. S The increased use of technology and its impact on currency of skills, how work gets completed, when it gets completed, etc. S The blurring of work/nonwork boundaries. S Work/life conflicts. Being available around the clock exacerbated the immediate-gratification challenge that had been growing in the working world, increasing work stress. The challenges associated with not interacting with other people have created a host of mental and emotional challenges: loneliness,


isolation, focus issues, and depression, among others. During the pandemic, Panchal et al. (2021) noted that four in 10 adults in the United States have reported symptoms of anxiety or depressive disorder, a share that has been largely consistent, up from one in 10 adults who reported these symptoms before the pandemic. Kearney et al. (2021) found that over 40 percent of adults say the coronavirus has had a negative impact on their mental health and that “school closures and lack of childcare had an even larger impact on parents with children.” Negative impacts on workers’ mental health and well-being include “difficulty sleeping (36 percent) or eating (32 percent), increases in alcohol consumption or substance abuse (12 percent), and worsening chronic conditions (12 percent) due to worry and stress over the coronavirus.” Because emotional trauma, like post-traumatic stress disorder (PTSD), normally lasts longer than the event, these mental and emotional challenges will impact us over the next few years, creating a whole host of stress-induced syndromes. Added to this is an increase in attention deficit disorder in kids (too little supervision and too many distractions), and many kids seem to have lost most of a year of school. Economic disruption extends far beyond just money—it can

fundamentally change society. But other issues were exposed as well.

What’s the New Normal for the Water Industry? So how does all of this affect utilities? First, there’s the economics. More remote work and shopping could mean less commercial building, which impacts the tax base. Less demand for commercial office space and retail space may cause current commercial values to fall, compounding the tax-base issue, which means politicians will look to water and sewer funds to balance generalfund budgets, just like they did after 2008. Demands will be altered, affecting treatment, supply, and revenues. The commercial sector often drives per capita water use, so less commercial activity could cause reductions in water use by current employment sectors (meaning less revenue). Bedroom communities may have higher demands, since people are home more, creating a need to find more water and wastewater treatment capacity there. Both will impact spending on deferred maintenance needs and may alter the current distribution of services. Work will change. Many employees will ask for and expect remote work options. Demands for flexible hours, accommodations for home

childcare, benefits, and less stress on the job may be required to secure these workers as well. These will be job benefits that will need to be available going forward to attract and retain workers. Yet, while some jobs can be done remotely with little disruption, those done by field workers and operators cannot. Like construction, those jobs require people to be at the worksite. Since the economy requires safe water and sewer services, we should consider reclassifying our operators and field staff as essential workers, just like police and firefighters, because we, like they, provide public health, safety, and welfare services to the community. The competition for products that have supply-chain challenges is apparent. Disruptions exposed the fact that the supply chain for products is far weaker than we thought. Getting simple things, like medicine, toilet paper, disinfectants, etc., could easily be disrupted by world economic events. Because American industries outsource so much to other countries to take advantage of low labor costs and keep prices down, the economy is subject to more disruptions. The differences across the world with COVID, business openings and closings, and transportation have slowed the economic recovery because components are not readily available in Continued on page 26

Continued from page 25 some sectors. For example, the lack of computer chips from Taiwan and China has impacted automobile manufacturing in the U.S. Those F150s (and others as well) are sitting in Detroit waiting of chips, increasing costs and delaying arrival. Many utilities rely on work trucks for their operations. Supply chains affect chemical use as well. Utilities have shut down ozone systems because the oxygen is needed for hospital ventilators. Other chemical costs have increased due to supply-chain and demand factors. The ability to react to price

changes in current budgets demonstrates the lack of “nimbleness” the elected officials have in reacting to these challenges, something we all knew. That needs to change if we are to secure the products and services we need. Lumber costs went up by a factor of five, and the price of polyvinyl chloride (PVC) materials doubled in three months. Both have retreated recently, but not to pre-COVID levels. As we have already seen, some workers, fed up with the stress on the job, may figure they have invested well enough to leave the job market permanently—there may be as many as 11 million

workers who made this choice. With them went a huge amount of institutional knowledge. Utilities are not immune to this worker shortage. Paying more to get field employees who will work onsite in an environment where they can be exposed to COVID will be an enduring challenge for us. And as for knowledge capture— well, we need to start using computer tools to collect that knowledge before it’s permanently lost. Utilities are among the most at risk to this knowledge loss. Geographic information systems (GIS) and other tools, when integrated with field staff, can provide engineers and managers with the data needed to make better decisions. Top-down approaches may be less valuable. So, the immediate challenges are many, but it takes little to see the next set of challenges. Other crises affect our industry, and our ability to meet the challenges presented is critical to our success. Climate change, for one, is going to alter the water balance. Too much, too little, wrong time, too much uncertainty—these factors are already driving change to our perceptions of water supplies (potable reuse is on the table now!). The sustainability of water supplies, and their reliability, are going to drive options like potable reuse when the population continues to grow and climate is a supply-disruption factor. Data continue to indicate that we are not spending enough to catch up with the deferred maintenance obligations. More problematic is the way to calculate these involved replacement values, which are climbing rapidly. So, another major challenge it to figure out your assets and how far behind you currently are. Then there is the need to prioritize infrastructure repairs and replacement to reduce risk (Bloetscher, 2019). I’m currently working on a model for this that is simple to implement, but some costs are staggering and will require major changes in rates and investments. With the need to build sustainable infrastructure is the need to be able to sustain finances, build strong reserves, bank money for large expenses, and perform ongoing replacement of pipelines. Bond issues create a need to raise rates, so paying as you go can help, but most rates are not what they need to be to create the sustainable finances, and elected officials pushing back to raising rates is significant in many communities. Finally, there’s that people problem. The lack of candidates for operations and field jobs is troubling. A major discussion point at our recent FSAWWA past chairs forum is that low local government pay scales may be a barrier to these jobs. Maybe of our operations people need to get paid like the essential frontline workers they are. Already local governments have been priced out of the engineering graduate market. The students are getting offers that average nearly $70,000 per year, plus benefits. Many government


pay scales for engineers start in the high $40,000s and low $50,000s, so there is no chance to get highquality candidates at these pay scales. Pay-scale adjustments indicate that costs will rise, which will require local entities to adjust and adapt, but costs for consultants will also increase in line with the laws of supply and demand for these employees. There are starting salaries of $25,000 per year for operators and field jobs, which is below the poverty level in many communities. Operator and field staff salaries are probably far off of what is needed, so people will only come to work “when they feel safe and better-compensated.” We may need to pay a lot more to attract and keep new people. Comparing ourselves to other utilities gives us bad feedback; we need to look at similar skills in other industries, like construction. Once people are found to do the work, there is a need to keep training them, retaining them, and creating a positive environment. We need to bring in more of the next generation of people to the industry, which means overcoming many barriers. While pay and flexibility are issues, they are not the only ones. A recent survey of the water industry noted that the biggest issue identified by both seasoned workers and young professionals (YPs) was the existence and perception of too much politics in the industry, from both local and

state governments. The YPs saw this as a bigger issue than the non-YPs (see Figure 1). People do not like to work in difficult environments. There are agencies where the environment is just too toxic, with lack of trust, authoritarianism, competition, favoritism, poor communication, too many politics, etc. Retaining good people is impossible in these situations (good people are the first to leave). It means we need to build good leadership across the industry that will improve the workplace and advocate for the public. It’s hard to define good leadership because it comes in many forms and is often specific to the approach to a situation. A football quarterback, who is a great leader on the field, might not be the best choice to lead the reorganization of a major corporation (Bloetscher, 2019). Both positions require leadership, but the skill sets required for the positions are situational. The same survey I mentioned indicated that the YPs saw leadership within professionals more than non-YPs. No other category more greatly differed between groups. Interestingly, neither group saw leadership at the executive or political level (see Figure 2). So, let’s consider COVID as a portent of the future challenges we will face—it was the trial run. It has identified certain issues that need to be dealt with now. It told us we are too slow to

react and too slow to communicate the correct message. Leadership, judgment, consideration, accommodations, and embracing our team are needed in the new normal. This is part of our public health, safety, and welfare obligations.

Conventional Lime Softening: Another Water Treatment Method Explained Kenneth Enlow

President, FWPCOA

G

reetings everyone. November is here and we are moving into the holiday season. I hope you all have a healthy and happy Thanksgiving with your family and loved ones. For this column, I would like to continue with the basic concepts of water treatment and talk about conventional lime softening.

The treatment of water with high hardness in conventional treatment processes is still practiced in many locations, although membrane softening has become more popular with the advancement of low-pressure membrane options. Membranes do offer the advantage of removing dissolved inorganics, as well as organics in groundwater that are high in hardness, and natural organics, such as humic and fulvic acids. Conventional lime softening will usually treat this type of groundwater with a coagulant as part of the lime softening process where the organics are a concern. Conventional lime softening is usually accomplished in conventional solids contact treatment units of some design. Lime and/

or soda ash, also known as sodium carbonate (Na2CO3), is introduced to the water supply entering the treatment unit reacting with the hardness in the water, forming a calcium carbonate (CaCO3) precipitate that is removed as a solid. The treatment process is usually preceded by aeration to strip carbon dioxide (CO2) from the raw water as the lime will react with the CO2 to form CaCO3 precipitate. Hardness in water is caused primarily by calcium and magnesium ions in solution. Total hardness, for practical treatment purposes, is considered to equal the sum of the calcium hardness and magnesium hardness in both the carbonate and noncarbonate forms. Softening with lime is achieved by means of chemical precipitation. By adding a controlled dose of quick lime, which is calcium oxide (CaO), usually as a slurry in the form of calcium hydroxide, or Ca(OH)2, the pH of the treated water is raised to the point where calcium bicarbonate, or Ca(HCO3)2, and magnesium bicarbonate, or Mg(HCO3)2, are converted to CaCO3 and magnesium carbonate (MgCO3). This reaction converts the Ca(HCO3)2 from a soluble state (in solution) to an insoluble state (out of solution) and settles out as a solid. The MgCO3 is still soluble, so a second reaction is needed to convert it to an insoluble form. More lime is added to the point where MgCO3 converts to an insoluble state forming magnesium hydroxide, or Mg(OH)2, which will precipitate as a solid. Optimum pH for calcium removal is 9.4 standard unit (SU) and optimum pH for magnesium removal is 10.5 SU. A typical softening range is 80 to 90 mg/L. Carbonate hardness is removed by the addition of hydrated lime, or Ca(OH)2, in the form of a slurry. S C alcium noncarbonate hardness is removed by Na2CO3. S Magnesium noncarbonate hardness is removed by Ca(OH)2 and Na2CO3. Once the softening process is completed, the treated water will have a high pH, depending on the extent of the hardness removal process.


The water must be stabilized after the treatment process. Stabilization of softened water is usually accomplished by recarbonation. This method involves bubbling CO2 gas into the treated water in order to form carbonic acid (H2CO3), a weak acid that dissociates and releases hydrogen ions (H+), which then react with the excess Ca(CO)3 and Mg(OH)2 and converts them back to the soluble forms as Ca(HCO3)2 and Mg(HCO3)2. Another method used to stabilize softened water is referred to as split treatment. Only a portion of the raw water is softened and a bypass stream of raw water is blended with the treated water after softening. This method uses the CO2 and bicarbonate (HCO3) alkalinity of the raw water to stabilize the treated water.

What is Hardness? There are two kinds of hardness: carbonate (temporary) and noncarbonate (permanent). The carbonate hardness is caused by calcium (Ca) and magnesium (Mg) carbonates (CO3) and HCO3. The noncarbonate hardness is due to Ca and Mg sulfates and chlorides. The total hardness in a water supply is composed of the carbonate hardness plus the noncarbonate hardness. The HCO3, CO3, and hydroxides (OH) that may occur are known as alkalinity and the forms of alkalinity present in the water are combined together under the term total alkalinity (TA). There are methods to determine the concentrations of alkalinity and hardness in the water. Knowing these concentrations, we can calculate the noncarbonate hardness. The relationship between the total, carbonate, and noncarbonate hardness, and the TA, can be expressed in the following equations: S T otal hardness = carbonate + noncarbonate hardness S T A = carbonate hardness S T otal hardness - TA = noncarbonate hardness

S HCO3 never appears where OH exists. The forms of alkalinity can be determined by volumetric titration, which utilizes a .02N (normal) sulfuric acid and the indicators methyl orange (M alkalinity) and phenolphthalein (P alkalinity). The methyl orange measures the TA (all forms) and the phenolphthalein measures all of the OH and half of the normal carbonates. Carbonates of Ca and Mg are the products of reaction of lime with Ca and Mg bicarbonates. To determine the three forms of alkalinity from the results of the TA and phenolphthalein alkalinity (PA) titration, the following set of rules applies to those waters in which the total hardness exceeds the TA: 1. Where there is no PA present all the alkalinity present is due to HCO3. 2 x PA = 0 2. Where phenolphthalein is present but 2 x PA is less than TA then 2 x PA equals normal

carbonates and the difference between 2 x PA and TA equals HCO3. 3. Where 2 x PA equals the TA all alkalinity present is due to normal carbonates. 2 x PA = TA. 4. Where 2 x PA is greater than the TA the difference is due to OH and the carbonates are equal to the TA minus the OH. From the following water analysis, we can apply the rules and determine the forms of alkalinity present. Sample: #1 #2 #3 #4 TA mg/L 40 40 40 40 PA mg/L 0 18 20 24 Sample #1. All the alkalinity is HCO3. When there is no PA present there are no carbonates or OH (Rule 1). Continued on page 36

Solids contact softening basin

Alkalinity Explained Alkalinity may exist as HCO3, CO3, or OH. All three of these compounds can never be found together, but certain combinations can coexist. If lime is added to water it will combine with HCO3 and convert it to CO3. If lime is added in excess to that required to convert HCO3 to CO3, the excess lime will appear as OH. Some truisms are as follows: S H CO3 and CO3 can coexist. S CO3 and OH can coexist.

Continued from page 35 Sample #2. The PA is 18, which is half of the carbonates; therefore, 2 x 18 = 36, which is the carbonates present. The TA is equal to 40, which is all the forms. The 40 minus 36 equals 4, which is HCO3. So, 36 mg/L are carbonates and 4 mg/L are HCO3, which equals 40 mg/L and is the TA (Rule 2). Sample #3. The PA is 20, which is half of the carbonates; 2 X 20 = 40, which is equal to the TA, so all the alkalinity is carbonate (Rule 3). Sample #4. The PA is 24, which is half the carbonates; 2 X 24 = 48. In a previous paragraph it was stated that the PA measured half of the carbonates and all of the OH. In all of the samples up to now 2 x PA was less or equaled the TA. In this case, the 2 x PA is greater than the TA, so there is OH present (to calculate, the OH Rule 4 is applied). S 2 x PA = 48 (half carbonates + all OH) S 4 8 - 40 = 8 mg/L OH S 4 0 - 8 = 32 mg/L carbonates S 8 + 32 = 40 mg/L TA Always remember that the forms or combined forms of alkalinity must always equal the TA.

Explaining pH

Webster’s definition of pH is: p (potential) of H (hydrogen) = a measurement of the acidity or alkalinity of a solution. S A cids contain high concentrations of H+. S B ases contain high concentrations of hydroxyl (OH-) ions.

S N eutral (pH 7) is when there is an equal amount of H+ and OH- ions. The pH is a measurement of how acidic or basic a solution is. Because pH does not have a specific unit it’s often specified as an SU; an example is 7 SU. The pH scale is logarithmic, with each value being a 10-fold change in the solutions acidity/basicity. An acid releases (dissociates) H+ when mixed into water. S sulfuric acid (H2SO4) [ 2H+ + sulfate (SO4-2) Acids that dissociate readily are known as strong acids and acids that dissociate poorly are known as week acids. A base is any substance that produces hydroxyl ions (OH-) when it dissociates in water. S Sodium hydroxide (NaOH) is a strong base: NaOH [Na+ + OHS Ca(OH)2 is a weak base: Ca(OH)2 [ Ca+2 + 2OH-

Lime Explained Lime refers to either quicklime, the product that is produced by heating limestone to its dissociation temperature, or slaked lime Ca(OH)2, the product that is produced by the reaction of quicklime with water. Lime in the form of high-calcium quicklime (CaO3) readily reacts with water to form Ca(OH)2, which provides a pH of up to 12.454 SU when in an aqueous solution. The production of CaO3 requires a large amount of heat, which is generated in the kiln environment.

Types of alkalinity and pH

36 November 2021 • Florida Water Resources Journal

The quarried and sized high-calcium limestone travels through a rotary kiln and is subjected to high temperatures where the CaCO3 begins to dissociate with the resultant formation of CaO3. The minimum temperature for the dissociation of CaCO3 is 1648oF (898oC). For practical production purposes, however, the kiln temperature range is from an initial temperature of about 1750oF (954oC) to a final temperature of about 1950oF (1066oC). These temperatures can vary depending on the nature of the limestone being calcined. The CaO3 readily reacts with water to form Ca(OH)2. The reaction is highly exothermic (creates heat) and the process is known as slaking. The reaction is usually carried out in a slaker (a specially designed mixer), which through a process of rigorous mixing, makes certain that all of the quicklime has come into intimate contact with water and no unreacted quicklime remains. This concludes my presentation on conventional softening. I hope this information will be of some value to you to help you advance in your certification levels and your careers.

Cutting Water Pipe Safely With Power Saws

as, hydraulic, and pneumatic saws are all used to cut utility water pipes. The main difference is the type of blade used. Depending on the situation and type of pipe, a specific blade may be required; some blades, such as diamond blades, will cut a variety of materials. Be sure to choose the proper saw and blade for the material being cut, following the manufacturer’s recommendations for the type of finish that is needed. Using a saw or blade not designed to efficiently cut through a material will usually damage the tool and create a safety hazard for its operator and those nearby. Forcing a saw that is not big enough for the job can cause a kickback, which could be another safety hazard. Employees should be provided with specific tool training and have read the entire operating manual and manufacturer’s guide for the specific saw used on the job.

Before Each Use Carefully examine the cutting equipment. Look for the following: S Worn bearings S Damaged power cords

S S S S S

Faulty on/off switches Loose bolts or nuts Lubricant leakage Evidence of excessive rust Broken or damaged housing or casing

Inspect the cutting blade or chain to ensure that it is: S Sharp S Not crooked, bent, cracked, or split S Rotating in the proper direction S Securely fastened or bolted into place and does not wiggle loosely if tapped or vibrated gently by hand. In addition, check the safety guards to make sure that they are in place and secure and that the machine warning placards and labels are in place and legible. Follow the manufacturer’s recommendations on blade replacement and preventive maintenance. If the saw is damaged or if it needs servicing, put a tag on it indicating it should not be used. Mark on the tag what is wrong with the unit and arrange to either have the unit repaired, serviced, or disposed of.

Before Cutting When starting a job, do the following: SM ake sure the saw is in the off position prior to plugging it in. SW ear the appropriate personal protective equipment (PPE), including: •H ead protection with safety glasses and/or a face shield •H earing protection •R espiratory protection if necessary • S teel-toed safety shoes •C lose-fitting clothing and long trousers or, for chainsaws, special ballistic nylon reinforced chaps, pants, gloves, and boots SP roperly support and chock the pipe to be cut so it won’t move or flex during the cut. SF uel the saw, as appropriate, with the proper oil/ gas mixture. Never gas, lubricate, or service a running machine. SC lear the immediate area of people, tools, debris, and other obstacles. S I f work is taking place near traffic areas, wear high-visibility clothing and ensure that appropriate traffic management procedures are in place.

While Cutting To ensure safety throughout the job, adopt the following procedures: SM aintain good footing, with your feet shoulderwidth apart. S Keep the saw close to your body. S Position your body as close to the pipe as possible. SD on’t reach with the cutting tool. SW ork with slow, controlled movements. S Bend your knees if necessary. S Don’t rock the saw back and forth; allow the weight of the saw to help pace the cut. SN ever twist or turn the blade while cutting; make a straight, even cut. SW ork at a steady pace; never force the blade through the material. S Stay concentrated on the task of cutting.

S The use of gas-powered pipe saws within excavations requires the use of ventilation equipment to prevent carbon monoxide accumulation. S If a blade or saw appears to overheat, turn the tool off immediately and allow it to cool down. After it has cooled, check it carefully to make sure that neither the saw nor blade has been damaged.

Maintaining a safe environment in the entire work area vicinity is another important safety factor. Keep other people at least 100 feet away and make sure other workers who are close by have proper PPE. Saws are dangerous and maintaining control of the situation and focusing on the work goes a long way toward safe operation and a safe workplace. S

Other Safety Measures These tips are also important: SA lways allow the saw to turn off, power down, and stop moving before you take your attention away from it. Never leave the machine unattended while running. S Keep in mind that cutting and grinding is considered hot work. Never cut in the vicinity of flammable materials or in areas without proper ventilation. S Have first aid kits, fire extinguishers, and emergency call numbers in close proximity at all times. SD on’t exceed the maximum operating speed recommended by the manufacturer and never cut material not listed by the manufacturer of that saw and blade.

Investigating Bromide Leakage During Anion Exchange Regeneration Daniel A. Whalen and Steven J. Duranceau

T

he City of Sarasota (city) produces up to 12 mil gal per day (mgd) of potable water using cation exchange (CIX), reverse osmosis (RO), and tray aeration processes to serve its nearly 57,000 residents. Saving on salt import costs, the city currently regenerates its CIX system using filtered Sarasota Bay seawater in lieu of a high-strength brine (salt) solution. In efforts to reduce sulfate, the city has investigated the use of anion exchange (AIX) as an additional technology to its treatment portfolio. Moreover, the city would like to evaluate the viability of using filtered Sarasota Bay seawater to regenerate the proposed AIX process. An AIX pilot unit was constructed onsite at the city’s water treatment facility (WTF) and operated to evaluate the performance of two strong base chloride-form anion resins. Purolite A600E-9149 and Thermax A-32 resins were fed the city’s sulfate-laden ion exchange (IX) feed water and run to exhaustion. Regeneration of the resin media included a manufacturer-recommended solution of 10 percent salt and the city’s filtered Sarasota Bay seawater (seawater). Distilled water was used for rinse cycles postregeneration and samples were collected at periodic time intervals to determine resin performance and investigate the leakage of competing anions. Results indicate that AIX performance in both resins decreases when seawater is used to

regenerate compared to a traditional 10 percent salt solution. Bromide leakage was also observed in the treated AIX effluent of both resins under seawater regeneration conditions. Total trihalomethane (TTHM) formation potential of the bromide-containing effluent was analyzed and found to range from 134µg/L to 197µg/L after 168 hours (seven days) of formation. The main component of the TTHM concentrations at the 168-hour time period consisted primarily of bromoform, indicating that increased bromide concentrations in the treated pilot effluent contribute to the increase in formed disinfection byproducts (DBPs)

Introduction and Background Ion Exchange Process The IX is a process used in water treatment applications to remove aqueous ionic constituents by exchanging them with solid-phase ions of a similar charge. This is accomplished by synthesizing media with organic functional groups to obtain a charge at the media’s surface. The IX process used for the removal of negatively charged ions is known as AIX, whereas the removal of positively charged ions is accomplished with CIX. In addition to water treatment, IX is used in the production of deionized water, industrial purposes, purification of organic and

Daniel A. Whalen, Ph.D., P.E., is a project engineer with Globaltech Inc. in Boca Raton. Steven J. Duranceau, Ph.D., P.E., is a professor with the department of civil, environmental, and construction engineering (CECE) at the University of Central Florida in Orlando.

inorganic chemicals, analytical chemistry uses, and ion mixture separation processes (Schubert & Nachod, 1956). Generally in the form of spherical resin beads, IX media are configured in a fixed or fluidized bed fashion and housed in a vessel during operation. Water is passed through the media bed and aqueous ionic constituents are removed as they exchange with the resin media’s solidphase presaturant ion. As operation continues, the resin bed begins to saturate with the targeted constituent(s) and the treated effluent water begins to increase in the targeted constituent(s) concentration, known as breakthrough. Once the resin bed is fully saturated with the targeted constituent(s), the bed is considered exhausted and must be regenerated prior to subsequent operational use. Figure 1 displays a graph illustrating breakthrough and exhaustion of an IX process, where operational run time is on the x-axis and effluent concentration of the targeted constituent(s) is on the y-axis. Regeneration Methods Regeneration of an IX process involves the replacement of the original presaturant ion back onto the resin media, eluting the saturated targeted constituent(s) that have accumulated during operational use. This is achieved by running a solution comprised of a high concentration of the presaturant ion through the resin bed. In water treatment, the presaturant ion is typically chloride or sodium, allowing a high-strength sodium chloride (i.e., salt) solution to be used for regeneration purposes. Common regeneration methods involve the use of a 10 percent strength salt solution that is run counter-current through the resin bed for a period of time, followed by a short rinse cycle of feed or treated water prior to completion. The spent salt solution and rinse


water are typically considered waste streams, requiring disposal. Because the regeneration process comprises a large portion of the overall cost and maintenance of IX, alternative regeneration methods have been researched and investigated. Medina et al. (2018) recently compared efficiencies of a fresh salt solution, a reused salt solution, and a treated reused salt solution for additional brine management options. Studies have also been performed on regenerating IX resin through multiple stages using different-strength brine solutions (Korak et al., 2017). The comparison of different salts, such as potassium chloride, sodium bicarbonate, and potassium bicarbonate, were evaluated by Maul et al. (2014) to measure regeneration efficiencies and their overall life cycle environmental impacts; however, less research is available on the use of alternative brine streams, such as seawater. Wilf et al. (1980) tested the use of seawater from the red sea as a regenerate solution for a CIX process, resulting in a viable implementation of the process. Coastal water utilities could benefit from seawater regeneration of IX systems, but more research is needed to evaluate the impacts associated with competing ions in seawater, such as bromide. Additionally, the lower ionic strength of seawater, when compared to a solution of 10 percent salt, leads to a lower regeneration efficiency and subsequent leakage of previously removed ions during succeeding operational runs. Brominated Disinfection Byproducts It is known that chemical disinfectants and oxidants added to water form byproducts when in contact with natural organic matter and other inorganic material, like bromide. Among the many DBPs that can be formed, only a small amount is currently regulated under the U.S. Environmental Protection Agency (EPA) Safe Drinking Water Act (SDWA). Five of the current regulated DBPs contain bromide, making it an important parameter in DBP formation (Heeb et al., 2014). Ding et al. (2012) demonstrated that the specific removal of bromide from water prior to disinfection is a desired treatment objective in reducing DBPs. Recently, Szczuka et al. (2017) and Liu et al. (2018) identified increased DBP formation from a saline water source due to elevated levels of bromide. Considering that certain seawater matrices contain high concentrations of bromide, AIX processes using seawater regeneration may experience bromide leakage due to ion’s propensity to act as a competing anion to chloride.

Existing Treatment Conditions The city’s utilities department operates a potable water facility in the state of Florida, spanning a service area of 25 sq mi. Utilizing

two main water sources, the city pumps water out of the Upper Floridan aquifer through 51 groundwater wells to produce 12 mgd of finished water. The city’s treated water consists of a blend of RO permeate, CIX product water, and raw aerated bypass water prior to chlorination and distribution. The existing CIX process is currently regenerated using filtered Sarasota Bay seawater, saving on salt import and operations costs. Table 1 displays the average water quality parameters of the IX and RO feed water.   Cation Exchange Treatment At a capacity of 7.9 mgd, groundwater from the Upper Floridan aquifer is pretreated through tray aeration and chlorination at the Verna well field, approximately 22 mi from the city’s WTF. Approximately 2.3 mgd of the pretreated raw water is bypassed and blended with the WTF’s finished water, while the remaining 5.6 mgd is fed to the city’s CIX process for hardness removal. The existing CIX process consists of four softening vessels, three of which are in operation at full production, with the fourth in regeneration. A strong acid cation (SAC) resin in the sodiumform operating in a fixed bed configuration is utilized for the selective removal of calcium and magnesium. Regeneration of the resin beds are accomplished using chlorinated Sarasota Bay seawater that is pumped directly from the Sarasota Bay and filtered at the WTF prior to use as a regenerate solution for the SAC resin. Sulfur dioxide is added to the used IX regeneration waste stream to remove residual chlorine prior to deep well injection disposal. Reverse Osmosis Treatment Brackish groundwater from the city’s downtown well field is pretreated at the WTF with the addition of an antiscalant (Aquafeed 1025®) to suppress the formation of sparingly soluble salts

and fed through one-micron cartridge filters prior to membrane treatment. It is then delivered as feed water to the city’s RO process consisting of three two-stage process trains in a 28x14 pressure vessel configuration, housing six low-pressure RO membrane elements per vessel. Hydranautics CPA3 membrane elements are used in stage 1 and Hydranautics ESPA 2 elements are utilized in stage 2. Operating at 75 percent recovery, the RO process produces 4.5 mgd of permeate water, which is then post-treated through degasification and sodium hydroxide addition. The treated RO permeate water is blended with the CIX product water and raw bypass water prior to chlorination and onsite storage before distribution. The rejected concentrate water, approximately 1.5 mgd, is degasified and disposed of via deep well injection.

Materials and Methods Anion Exchange Pilot Unit A four-column, AIX pilot system was installed at the city’s WTF on behalf of Tonka WaterTM, a U.S. Water Brand. The pilot system is operated in a four-column design, where two columns combined is analogous to a full-length column. In this configuration, the effluent of the first column represents half-bed values and the effluent of the second column represents full-bed values. With the four-column arrangement, two full-bed anion resins can be operated in parallel for performance comparison and can be seen in Figure 2. Purolite A600E-9149 and Thermax A-32 strong base chloride-form anion resins were provided to the University of Central Florida (UCF) by the manufacturers and were tested for the targeted removal of sulfate under the operating parameters, displayed in Table 2.

column measured 3 in. in diameter, the achieved media bed depths allowed for a similar surface and volumetric loading rate to that of the city’s full-scale CIX system. Each column was also equipped with a pressure gauge at the influent and effluent orifices to monitor pressure drop changes throughout operations. Influent water to the pilot unit was supplied from the city’s onsite IX feed water storage tank and effluenttreated water was discharged to a 30-gal storage tank prior to disposal. Regeneration procedures were accomplished through the use of a 60-Hz centrifugal pump and an additional 30-gal storage tank to contain regenerate solutions. To determine the efficiency and impacts of using seawater to regenerate an AIX process, the columns were operated over 78 hours and 279 bed volumes until sulfate exhaustion was reached using the city’s IX feed water. The columns were then regenerated using filtered Sarasota Bay seawater in a counter-current flow configuration until effluent conductivity values matched that of the seawater, approximately 53,300µS/cm, and rinsed using distilled water in a co-current flow configuration until effluent conductivity values matched that of the city’s IX feed water, around 1,000µS/cm. Table 3 outlines the water quality characteristics of the filtered Sarasota Bay seawater.   Once regenerated, the columns were operated again over 78 hours, until sulfate exhaustion was reached.

collected in 125-mL plastic bottles at the start of operation, 18 hours into operation, and every four hours up to 78 hours of use. The same operationregeneration-rinse process was repeated using a 10 percent salt solution during regeneration procedures for comparison to seawater. Saturation loading curves were determined and competing anions were analyzed to identify the elution of any additional anions, which may have exchanged onto the anion resin during operational runs. It was found that during seawater regeneration conditions, bromide concentrations in the treated water samples exceeded that of the city’s IX feed water entering the pilot unit, indicating the occurrence of bromide leakage. Disinfection Byproduct Formation Potential Evaluation Upon determination of bromide as a competing anion, the operation-regenerationrinse process was repeated using only the Thermax A-32 resin, collecting bulk water samples in fivegal tote containers at periodic time intervals. Bromide concentrations were measured for each time interval to identify the time period at which the highest level of bromide was found. The bulk water sample containing the highest amount of bromide was retained for use in determining DBP formation potential of the treated water. To accurately evaluate brominated DBP formation potential of the treated AIX water, chlorine demand was first determined. This was accomplished by dosing several concentrations of chlorine and measuring the residual concentration over time, up to seven days. Chlorine dosage was identified as the dosage that obtained a chlorine residual between 0.2 and 1 mg/L after seven days of incubation at 30⁰C, resulting in a determined dosage of 2 mg/L. Using the determined chlorine dose, DBP formation potentials of the bulk water sample containing the highest amount of bromide were performed. The bulk water sample was split into two different sets: one sample with no alterations (no bypass) and one sample comprised of 33 percent IX feed water (33 percent bypass) to simulate the city’s current bypass configuration. The 33 percent bypass sample did not include blend additions of the city’s RO permeate and was not representative of the city’s final product water. The TTHM formation potentials were evaluated over a seven-day time period, while incubated at 30⁰C.

Results and Discussion

Subsequent operation-regeneration-rinse cycles of the AIX pilot unit were performed using seawater and 10 percent salt regenerate solutions. Columns were fed the city’s IX feed water during


operational runs. Saturation loading curves were prepared and reviewed for performance and efficiency of sulfate removal. Figure 3 presents the results of both runs, identifying breakthrough and exhaustion values. During seawater regeneration conditions, full-bed sulfate exhaustion was observed at 212 bed volumes for the Purolite A600E-9149 resin and 210 bed volumes for the Thermax A-32 resin. During 10 percent salt regeneration conditions, full-bed sulfate exhaustion was observed at 225 and 220 bed volumes for the Purolite and Thermax resins, respectively Treated effluent water samples were analyzed for the presence of additional anionic constituents. Concentrations of additional anions found in the treated effluent samples were compared to the city’s IX feed water characteristics in efforts to identify the occurrence of anion leakage from seawater. Bromide values in the treated effluent samples under seawater regeneration conditions were observed above the city’s IX feed water bromide concentration of <0.2 mg/L, seen in Figure 4a. In comparison, bromide values in the treated effluent samples under 10 percent salt solution regeneration conditions stayed below the city’s IX feed water bromide concentration for the majority of operation, as shown in Figure 4b. To further investigate the extent of bromide leakage under normal operating conditions, columns containing Thermax A-32 resin were regenerated with seawater and run until sulfate exhaustion was reached, collecting bulk water samples of the treated effluent at periodic time intervals. At 60 hours of operation, 215 bed volumes, a bromide concentration of 4.50 mg/L was observed in the treated effluent. Bulk water taken at this time was retained for use in determining DBP formation potentials. Figure 5 illustrates TTHM concentrations of the bromide-

containing effluent water reaching 134µg/L at 168 hours (seven days). When blended with a 33 percent bypass of the city’s IX feed water, TTHM concentration increased to 197µg/L at 168 hours. The TTHM formation is comprised of four regulated DBPs that include chloroform, bromodichloromethane, dibromochloromethane, and bromoform. The compositions of TTHM were evaluated to determine the impacts of increased

bromide concentration on brominated DBP formation. As observed in Figure 6, the major component of TTHM concentrations came from bromoform, a brominated DBP. At 168 hours, 85.7 percent of the bromide-containing effluent sample and 87.1 percent of the blended 33 percent bypass sample were comprised of bromoform. Continued on page 46

Conclusion During this study, two strong base chlorideform anion resins were tested at the pilot scale for their performance in removing sulfate, and were evaluated for the leakage of competing anions when alternative regenerate solutions were used. A manufacturer-recommended solution of 10 percent salt and filtered Sarasota Bay seawater was utilized to regenerate Purolite A600E-9149 and Thermax A-32 anion resins. Pilot column procedures involved operational runs of the anion resins until sulfate exhaustion was reached, regeneration of the resin media with different solutions, and a rinse cycle of distilled water. Samples were collected at periodic time intervals and analyzed to determine resin performance and anion leakage. Sulfate exhaustion decreased from 221 to 212 bed volumes in the Purolite resin under seawater regeneration conditions when compared with 10 percent salt. Similarly, sulfate exhaustion in the Thermax resin decreased from 220 to 210 bed volumes. Bromide leakage was identified in both anion resins when seawater was used for regeneration. The resulting bromide concentration at 60 hours of operation, 215 bed volumes, in the treated effluent of the Thermax resin was 4.50 mg/L. The TTHM formation of the bromidecontaining effluent sample reached 134 µg/L after 168 hours of incubation. When blended with 33 percent of the city’s IX feed water, the TTHM formation increased to 197 µg/L after 168 hours.

The TTHM concentrations were comprised primarily of bromoform, 85.7 and 87.1 percent, respectively, after 168 hours.

FWEA FOCUS

Biosolids: Regulations and Innovations Ronald R. Cavalieri, P.E., BCEE President, FWEA

B

Coauthor: Terry Goss, P.E.

iosolids legislation and regulation continue to be a high priority for the state of Florida. In March 2020 the Florida State Legislature passed Senate Bill 712 and the Florida Department of Environmental Protection (FDEP) initiated rulemaking for compliance with the new legislation. The Clean Waterways Act (Senate Bill 712) addresses several environmental issues, including provisions specifically related to water quality improvement and biosolids. The SB 712 and new rules under Chapter 62-640 Biosolids primarily affects land application for biosolids disposal and potential beneficial use. The bill requires new site

permits and permit renewals after July 1, 2020, to comply with the following provisions: S M eet a minimum unsaturated soil depth of 2 feet from the depth of biosolids placement when biosolids are applied. S N ot allow application on soils with a seasonal high water table (SHWT) within 6 inches of the soil surface or depth of biosolids placement unless the permittee provides reasonable assurance through the site nutrient management plan and water quality monitoring plan that land application will not cause or contribute to surface water quality violations or groundwater violations. S R equire enrollment in a Florida Department of Agriculture and Consumer Services (DACS) best management practices (BMPs) program. S A ll site permits will have to comply with the DACS BMPs enrollment requirement and the SHWT provision by July 1, 2022. S N ew and renewed permits after July 1, 2020, must include a permit reopener condition to add a compliance date of no later than one year after the effective date of new biosolids rules.

S A ll permits must comply with the new rules no later than two years after the effective date of the new biosolids rule. S A municipality or county may enforce or extend a local ordinance, regulation, resolution, rule, moratorium, or policy adopted before Nov. 1, 2019, relating to the application of Class A or Class B biosolids until the regulation, resolution, etc., is repealed by the municipality or county. The proposed amendments to Chapter 62640, F.A.C., became effective on June 21, 2021. House Bill 1309 was signed into law on June 21, 2021, ratifying the proposed biosolids rule (see Chapter 2021-153, Laws of Florida). Based on Section 403.0855, F.S., and the deliberations of the biosolids technical advisory committee, the rule revisions were developed to minimize the migration of nutrients, specifically phosphorus, to prevent impairment to waterbodies.

Impact on Existing Biosolids Management The new rules could have a significant impact on wastewater treatment plant (WWTP) owners/operators (utilities) that choose land application for biosolids disposal. There are approximately 130 permitted land application sites in Florida. Haulers are the most common site permittees and utilities typically contract with the haulers/appliers instead of applying the biosolids themselves. A likely consequence of the new rules is that existing permitted land application sites will not meet the requirements for permit renewals and/or new site permits. The WWTP owners/ operators with existing hauler contracts will be forced to consider other options for disposal or potential beneficial use, including transfer to another facility, landfilling, incineration, or other innovative technologies. Based on the FDEP Statement of Estimated Regulatory Costs (SERC), the new rules under 62-640 will cause an estimated 75 percent reduction in land application rates.

Innovative Technologies

Existing Permitted Land Application Sites

48 November 2021 • Florida Water Resources Journal

The new Florida regulations add further challenges and complexity to biosolids management, on top of existing challenges, which include odor, public perception, enduse reliability, rising tipping fees, emerging contaminants, and economic concerns


associated with aging infrastructure. With decreasing availability for land application, more biosolids will ultimately require additional outlets, and using landfill to make up this difference is not sustainable. With the change in regulations there will be further drivers to move to Class A biosolids products (or better) and reduce the mass and volume of solids leaving WWTPs. The move to Class A may be ushered in with additional Class A digestion facilities (such as thermophilic digester or thermal hydrolysis), but these processes will still produce a cake product that requires a reliable outlet. Further investment into additional drying or composting facilities may also be warranted, as they produce higher-quality and moremarketable products, but these facilities are expensive and require significant marketing efforts to maintain reliable uses. Furthermore, even Class A biosolids will be subject to nutrient limits and the market will likely become saturated as more utilities choose this option. Currently there are technology innovations and opportunities that are available or in development that may augment current biosolids management disposal/beneficial use options and allow utilities to avoid landfilling or land application of dewatered biosolids. The innovations include thermal technologies that go beyond drying or traditional incineration. These processes include gasification, pyrolysis, hydrothermal, and supercritical processing options, which are still new and not well-established in the biosolids market, but there is great interest in the next generation of development. These processes are being considered to significantly reduce the mass and volume of biosolids generated and produce potentially useful byproducts, such as biochar, oil, or other nutrient- and mineral-rich byproducts. Thermal technologies with combustion, gasification, and pyrolysis applied to biosolids are still innovative for the biosolids market, but they are not necessarily new to it. Veolia/ Kruger has BioCon™ and an energy recovery system that uses dried biosolids as the fuel source for a biosolids belt dryer, which has been in operation in Buffalo, Minn., for over a decade. Further research is currently ongoing to see if this could be used to manage perand polyfluoroalkyl substances (PFAS)-laden biosolids. Locally, a fluid bed gasification system was operated for several years in Sanford, Fla., before being decommissioned; however, this technology is being revived by Aries Clean Energy and a new installation in Linden, N.J., is scheduled to be commissioned this year.

Ecoremedy installation in Morrisville, Pa., and the biochar product. (photo: ecoremedyllc.com)

Bioforcetech and Ecoremedy are other manufacturers that offer biosolids gasification and pyrolysis systems and there are now operational facilities in California and Pennsylvania. Additional pyrolysis systems are being commissioned by Biowaste Pyrolysis Solutions and Anaergia in both New York and California. This new wave of development in the industry shows that there is a driver and a need for alternative biosolids management solutions. There are more innovative hightemperature/high-pressure processes that are currently in early development. Unlike the gasification and pyrolysis process, these do not require thermal drying and the feedstock to the reactors is dewatered sludge. These processes, including supercritical water oxidation and hydrothermal liquefaction, are also not necessarily new and have been tested in the past. New technology companies are working to overcome previous challenges for development of these applications. The next generation of supercritical water oxidation is currently being developed by 374Water and a demonstration facility is located at Duke University in Durham, N.C., for testing various waste feedstocks. Hydrothermal liquefaction is currently being pioneered by Genifuel, and the process developed in collaboration with Northwest Pacific Laboratories is looking to use biosolids and other feedstock, like algae, for conversion to a biocrude product.

Conclusion This is a challenging time for biosolids management, but with challenges come great opportunities. Changing regulations will lead to further innovations, with upcycling biosolids that can help address Florida’s environmental issues and improve water quality and continue to move biosolids management into a circular economy. The circular economy employs a system where there are no waste products and all byproducts are reused or recycled. This resilient approach contrasts with a take/make/waste linear economy.

1. B ) A temporary connection between a private water well and a potable water main or service.

Per FAC 62-550.200(27), Definitions, “‘Cross Connection’” means any physical arrangement whereby a public water supply is connected, directly or indirectly, with any other water supply system, sewer, drain, conduit, pool, storage reservoir, plumbing fixture, or other device which contains or may contain contaminated water, sewage. or other waste, or liquid of unknown or unsafe quality which may be capable of imparting contamination to the public water supply as the result of backflow. Bypass arrangements, jumper connections, removable sections, swivel or changeable devices, and other temporary or permanent devices through which or because of which backflow could occur are considered to be cross connections.”

2. A ) Backpressure and backsiphonage

Per FDEP’s Cross Connection website, “Backflow is the undesirable reversal of flow of nonpotable water or other substances through a cross connection and into the piping of a public water system or a consumer’s potable water system. There are two types of backflow: backpressure backflow and backsiphonage.”

3. D ) CWSs serving more than 10,000 persons

Per FAC 62-555.360(2)(b), Cross Connection Control for Public Water Systems, “Each CWS serving more than 10,000 persons shall prepare and submit cross connection control program annual reports. The first annual report shall cover calendar year 2016 and subsequent annual reports shall cover each calendar year thereafter. These reports shall be prepared using Form 62-555.900(13), Cross Connection Control Program Annual Report.”

4. C ) Legal authority for the CCC program

Per FAC Table 62-555.360-1: Minimum Components that Each Community Water System (CWS) Shall Include in Its Written Cross Connection Control (CCC) Plan, item I: Legal authority for the CWS’s CCC program – i.e., an ordinance, bylaw or resolution, or water service rules and regulations.”

5. C ) Reduced-pressure principle assembly (RP)

Per FDEP’s Cross Connection website, “An RP is a mechanical backflow preventer that consists of two independently acting, spring-loaded check valves with a hydraulically operating, mechanically independent, spring-loaded pressure differential relief valve between the check valves and below the first check valve. It includes shutoff valves at each end of the assembly and is equipped with test cocks. An RP is effective against backpressure backflow and backsiphonage and may be used to isolate health or nonhealth hazards.”

6. C) May be easily bypassed

Per FDEP’s Cross Connection website, “An air gap is a vertical, physical separation between the end of a water supply outlet and the flood-level rim of a receiving vessel. This separation must be at least twice the diameter of the water supply outlet and never less than 1 inch. An air gap is considered the maximum protection available against backpressure backflow or backsiphonage but is not always practical and can easily be bypassed.”

7. A) Annually

Per Table 62-555.360-1, Item III.D, “This policy shall specify the frequency for testing backflow preventer assemblies being required at or for service connections, shall specify qualifications for persons testing such assemblies, and shall specify test procedures for such assemblies. Assemblies being required at or for nonresidential service connections pursuant to Table 62-555.360-2, which appears at the end of Rule 62-555.360, F.A.C., shall be tested after installation or repair and at least annually thereafter and shall be repaired if they fail to meet performance standards. Assemblies being required at or for residential service connections pursuant to Table 62-555.360-2 shall be tested after installation or repair and at least biennially thereafter and shall be repaired if they fail to meet performance standards.”

8. C) RP

Per Table 62-555.360-2: Categories of Customers for Which Each Community Water System (CWS) Shall Ensure Minimum Backflow Protection is Provided at or for the Service Connection from the CWS to the Customer, “Car wash – RP.”

9. B ) In locked and labeled vaults or service boxes

Per FAC 62-610.469(3), Application/ Distribution Systems and Cross Connection Control, “Except as specifically allowed in this paragraph, above ground hose bibbs (spigots or other hand-operated connections) shall not be present. Hose bibbs shall be located in locked vaults, service boxes, or compartments which shall be clearly labeled as being of nonpotable quality (bearing the words in English and Spanish “Do Not Drink” together with the equivalent standard international symbol). Hose bibbs which can only be operated by a special tool may be placed in nonlockable vaults, service boxes, or compartments clearly labeled as nonpotable water (bearing the words in English and Spanish “Do Not Drink” together with the equivalent standard international symbol).”

10. A) Do Not Drink

Per FAC 62-610.469(7)(f), Cross Connection Control, “All reclaimed water valves and outlets shall be appropriately tagged or labeled (bearing the words in English and Spanish “Do Not Drink” together with the equivalent standard international symbol) to warn the public and employees that the water is not intended for drinking.”
