EPA Issues Guidance to States to Reduce Harmful PFAS Pollution

The U.S. Environmental Protection Agency (EPA) recently released a memorandum to states that provides direction on how to use the nation’s bedrock clean water permitting program to protect against per- and polyfluoroalkyl substances (PFAS).

The guidance, which outlines how states can monitor for PFAS discharges and take steps to reduce them where they are detected, is part of the agency’s holistic approach to addressing these harmful substances, known as “forever chemicals,” under the PFAS strategic roadmap from EPA.

This action is a critical step in EPA’s efforts to restrict PFAS at their source, which will reduce the levels of PFAS entering wastewater and stormwater systems and ultimately lower people’s exposure to PFAS through swimming, fishing, drinking, and other pathways.

“The EPA is following through on its commitment to empower states and communities across the nation to address known or suspected discharges of PFAS,” says Radhika Fox, EPA assistant administrator for water. “This action builds on successful and innovative efforts already used by several states to safeguard communities by using the Clean Water Act permitting program to identify and reduce sources of PFAS pollution before they enter waters in the United States.”

Memorandum Guidance

The memo, titled “Addressing PFAS Discharges in National Pollutant Discharge Elimination System (NPDES) Permits and Through the Pretreatment Program and Monitoring Programs,” will align wastewater and stormwater NPDES permits and pretreatment program implementation activities with the goals that are in EPA’s strategic roadmap. The memo recommends that states use the most current sampling and analysis methods in their NPDES programs to identify known or suspected sources of PFAS and to take actions using their pretreatment and permitting authorities, such as imposing technology-based limits on sources of PFAS discharges. The memo also helps the agency obtain comprehensive information through monitoring on the sources and quantities of PFAS discharges, informing other EPA efforts to address PFAS.

Several states have already demonstrated the benefits of leveraging their administered NPDES permit programs to identify and reduce sources of PFAS before these chemicals enter treatment facilities and surface waters.

Michigan, for example, is partnering with municipal wastewater treatment facilities to develop monitoring approaches to help identify upstream sources of PFAS. The

state has been able to leverage its monitoring information to work with industries, such as electroplating companies, to substantially reduce PFAS discharges.

North Carolina has also successfully leveraged its NPDES program to develop facility-specific, technology-based effluent limits for known industrial dischargers of PFAS. The memo urges states to replicate these approaches and use others to identify and reduce PFAS discharges.

New Recommendations

The memo also builds on the agency’s April 2022 memo to EPA regions by expanding the audience to states and including new recommendations related to biosolids, permit limits, and coordination across relevant state agencies. The memo provides recommendations to NPDES permit writers and pretreatment coordinators, rooted in the successful use of these tools in several states, on monitoring provisions and analytical methods and the use of pollution prevention and best management practices.

These provisions aim to help reduce PFAS pollution in surface waters as the agency also works to promulgate effluent guidelines, finalize multilaboratory validated analytical methods, and publish water quality criteria that address PFAS compounds. S

National Groundwater Awareness Week is Coming!

In 2023, National Groundwater Awareness Week is March 6-12, which is a great time to learn how to make groundwater safe. Groundwater is the most accessed source of freshwater in the world and it also accounts for half of the world’s drinking water.

National Groundwater Awareness Week is an annual observance sponsored by the National Groundwater Association (NGWA) highlighting how important groundwater is to people’s health and the environment.

Groundwater Explained

Water is one of the world’s most vital resources supporting life. Animals, plants, and humans all depend on water for their continued existence. Humans use water for myriad day-today activities like cooking, drinking, bathing, farming, manufacturing, medical uses, and more.

Water covers 71 percent of the earth’s surface, in contrast to land mass. One might think that this would make water readily available for consumption, but 97 percent of that water is ocean water—salty and undrinkable. Only 3 percent of the earth’s water is fresh and suitable for drinking and much of this water is groundwater.

Groundwater is water found below the earth’s surface in spaces between rock and soil. Surface water is water that collects above the earth’s surface, such as in streams, rivers, lakes, or oceans. Thirty percent of all the fresh water on earth is groundwater, while the other 70 percent is surface water. Groundwater supplies water to wells and springs and is an important source of water for public water systems and private wells

in the United States. An estimated 145 million Americans get their tap water from a groundwater source.

National Groundwater Awareness Week is the time of the year to advocate for the cleanliness and safety of groundwater. It’s a reminder that the importance of groundwater can’t be taken for granted.

Five Important Facts About Groundwater

1. Amount of groundwater available

It’s estimated that there are about 2.8 trillion gallons of groundwater in the world, making up 30.1 percent of the world’s freshwater.

2. Cleanliness of groundwater

More often than not, groundwater is clean and ready to drink because the soil filters the water, holding chemicals, living organisms, and minerals and allowing only water through to the aquifers.

3. A major addition to surface water

Hydrologists estimate that groundwater contributes about 40 to 50 percent of the water that flows into streams, lakes, and rivers.

4. Dependence on groundwater

About half the world’s population depends on groundwater for drinking. In the U.S., it provides 44 percent of the drinking water supply.

5. The largest aquifer in the world

The Great Artesian Basin in Australia is the largest and deepest aquifer holding groundwater, underlying 22 percent of the continent.

Frequently Asked Questions About Groundwater

Why is groundwater so important?

It provides the largest source of freshwater. As stated earlier, the largest percentage of water on earth is ocean water, which is practically undrinkable because of its saltiness.

Is there an alternative to groundwater?

Yes. The major alternative is rainwater, but since it doesn’t rain all year round, and in all places, the easy availability of groundwater makes it a better option.

What problems can arise with groundwater?

Several problems can arise with groundwater, including drying of wells, contamination of the water, waterlogging and salinity, saltwater encroachment, and more.

Why National Groundwater Awareness Week is Important

Water is Life

Water is very important to the existence of life. Be it humans, animals, or the earth itself, nothing can live without water. This makes National Groundwater Awareness Week unique and necessary.

It’s a Time for Information and Advocacy

This event is important to help in fighting against debilitating waterborne diseases that can be in water wells because of negligence. A yearly check-up would help to detect and prevent germs and bacteria that can be very harmful to the safety of the water.

Protection for the Future

Because freshwater is readily available in most societies, it’s easy to forget its importance and why it must be guarded and protected. This event is a reminder of the need to protect groundwater, especially for the future.

Protection of Well Water

One of the ideas behind awareness week is to advocate for the safety of well water. Water customers who are private well water owners should schedule a professional to test their

water yearly, and in the case of any problems, treat them immediately.

Protect Wells From Harmful Substances

This is the time to be security conscious about private wells. Make sure they’re free of every chemical and harmful substance that can find itself inside the wells and contaminate the water.

Inform Others About Groundwater

Many people know nothing about groundwater and its importance, which can be surprising. As someone in the water industry, share your knowledge with others and explain how to keep groundwater safe.

Groundwater Contamination

All groundwater sources should be protected from contamination (germs and harmful chemicals). Protecting the safety of groundwater is an important priority for countries throughout the world. Most of the time, U.S. groundwater is safe to use; however, groundwater sources can become contaminated with germs, such as bacteria, viruses and parasites, and chemicals, such as those used in fertilizers and pesticides. Contaminated groundwater can make people sick and harm the environment.

Groundwater Infrastructure Requires Regular Maintenance

Groundwater sometimes contains naturally present germs and harmful chemicals from the environment, such as arsenic and radon. More often, however, human activities contaminate groundwater. These causes can include incorrect use of fertilizers and pesticides; poorly situated, constructed, or maintained septic systems; improper removal or storage of wastes; mining and construction; and chemical spills at work sites.

Contamination of groundwater systems can lead to outbreaks of disease. Previous outbreaks have occurred either because the groundwater was untreated or because of problems with water treatment.

The most common germs identified in groundwater outbreaks include:

S Shigella

Other germs that cause outbreaks from groundwater include Cryptosporidium (a parasite), E. coli (a bacterium), and assorted viruses. From 2009 to 2017, 143 outbreaks linked to groundwater systems were reported to the Centers for Disease Control and Prevention (CDC).

More information about some of the most common environmental chemicals that may be in community water supplies can be found at the CDC Environmental Public Health Tracking Network.

The presence of germs and harmful chemicals in groundwater can lead to health problems, including diarrhea, reproductive problems, and nervous system disorders. Infants, young children, pregnant women, the elderly, people whose immune systems are weakened, and chemotherapy or transplant patients may be more likely to get sick from certain germs and chemicals.

Concerns for groundwater contaminants led the U.S. Environmental Protection Agency (EPA) and individual states to develop regulations to protect public water systems, such as the 2006 Groundwater Rule.

An emerging concern in recent years is the occurrence of pharmaceuticals and personal care products in water. Much research remains to be done to assess the health risks of trace amounts of these items, but careful and safe disposal strategies for these substances are increasingly being advocated.

Groundwater Sources

Public Water Systems

The EPA regulates drinking water quality in public water systems. Customers can find out more about their local drinking water quality and possible contaminants by viewing their Consumer Confidence Report (CCR), which most utility companies are required to provide to customers. Public water systems are required to treat drinking water to federal quality standards;

however, it’s up to private well owners to make sure their water is safe.

Private Wells

An estimated 43 million Americans get their water from private groundwater wells, which are not subject to EPA regulations. Private groundwater wells can provide safe, clean water, but contamination that can cause sickness also can occur in well water. State and local health departments provide information to help well users protect their drinking water.

National Groundwater Monitoring Network

The National Groundwater Monitoring Network (NGWMN) started as a program of the Subcommittee on Groundwater of the Federal Advisory Committee on Water Information (ACWI). The NGWMN is a compilation of selected groundwater monitoring wells from federal, state, and local groundwater monitoring networks across the U.S. The design for the network is presented in the document “A National Framework for Groundwater Monitoring in the United States.”

The NGWMN data portal provides access to groundwater data from multiple, dispersed databases in a web-based mapping application. The portal contains current and historical data, including water levels, water quality, lithology, and well construction. The NGWMN is currently in the process of adding new data providers to the network. Agencies or organizations collecting groundwater data can find out more about becoming a data provider for the network.

Funding to support data providers to the NGWMN is provided through U.S. Geological Survey (USGS) cooperative agreements. Agencies can also find information about the status of the USGS cooperative agreements.

The current 2023 NGWMN funding opportunity began on Sept. 30, 2022, and will be open until Jan. 26, 2023.

FWPCOA 2023 Spring State Short School and Fall State Short School

The FWPCOA 2023 Spring State Short School will be held March 13-17, 2023, at the Indian River State College in Fort Pierce. March 12, 2023, is Daylight Saving Time to throw everyone for a loop on the day of the board of directors meeting, and with St. Patrick’s Day on Friday, March 17, I may have to wear my leprechaun suit a few days earlier since I usually am not scheduled for anything on the last day of the short school.

The FWPCOA 2023 Fall State Short School is usually held in August (it’s not on

the event calendar yet, so again, keep an eye out for the exact week). Remember, this is when the bulk of the FWPCOA awards are presented, so look at the website, pick the appropriate award for one of your coworkers or employees, and get those nominations in before the usual June deadline for the August awards.

We look forward to having two more inperson, wonderful, and successful FWPCOA Spring and Fall State Short Schools!

Go to the website for event and awards details. For all events contact Shirley Reaves at (321) 383-9690 or fwpcoa@gmail.com, or Darin Bishop at (561) 840-0340 or memfwpcoa@gmail.com.

Florida Water Resources Conference

The Florida Water Resource Conference (FWRC) will be held May 31 through June 3, 2023, at the Gaylord Palms Resort in Kissimmee. There is new software and an updated website, which should improve the service and make the experience of registering much better. Being one of the dinosaurs in the group and not liking apps at all, the promise of having an app that provides a variety of functions and QR codescanning sounds pretty good to me. I can’t tell you how many times I’ve left a technical session without having signed in on the “green card” for CEUs.

The FWPCOA Operators Showcase will be held again on the first day of the conference, and we are already making plans for it to be as great a presentation as was provided last year. Always a good time and free beer!

The FWPCOA awards that are presented at the FWRC awards luncheon and annual meeting must have nominations submitted to Renee Moticker, FWPCOA Awards Committee chair, usually by March. This is a great opportunity to acknowledge outstanding individuals in our association.

The awards are:

S David B. Lee Award – Based on the operator’s plant operations and activities within the association.

S Pat Flanagan Award – Given by the state

14 January 2023 • Florida Water Resources Journal

association to an associate member, based on their assistance to operators and their contribution to the association.

S Richard P. Vogh Award – Given to the region judged most progressive during the year.

Please do not fail to attend this joint conference, sponsored by FSAWWA, FWEA, and FWPCOA; it’s a great networking and technical-session event. Additionally, if you are attending, consider volunteering to help with registration or as a moderator. Attendee registration opened on Dec. 1, 2022, so, if you haven’t registered, or reserved your room, get on it!

FWPCOA Meet and Greet

This is an annual event that I would like to see continued; maybe we can alter the name of the event slightly to reflect what actually happens there. Besides being a social event, we want to maintain the quality and initial content of it, and expound on more pronounced exposure of FWPCOA to utility hierarchy and help spread the word for our valuable training programs. The cost of this event should be on the association unless we can drum up some sponsorships or contributions.

Performance Evaluation of Cloth Disk

Primary Filtration to Increase Carbon Diversion Toward Net-Zero Water Resource Recovery Facilities

Several new filter technologies have been developed that can be used to increase primary treatment performance. In primary filtration (PF), filter technology is used to replace primary sedimentation.

The principal focus of this article is the performance of the first full-scale PF project using a fine pore cloth disk primary filter (CDPF) to maximize the diversion of carbon for the production of energy and to reduce energy usage. Performance data from related pilot-scale CDPF systems are included for process verification.

The removal performance for total suspended solids (TSS) from the three CDPF installations varied from 83 to 85 percent, as compared to 55 to 60 percent typically achieved with primary sedimentation. The removal performance for five-day biochemical oxygen demand (BOD5) from the three CDPF

installations varied from 46 to 58 percent, as compared to 32 to 38 percent BOD5 removal typically achieved with primary sedimentation. The full-scale CDPF results reported here are from several previous pilot and demonstration projects, as well as an ongoing research and demonstration project, conducted for the California Energy Commission (CEC), to demonstrate the potential energy savings that can be achieved through the implementation of CDPF.

Significance of and Technologies for Primary Filtration

Significant benefits that can result from the implementation PF, based on the results of previous studies (Caliskaner et al., 2015, 2016, 2017, 2019, 2020, 2021; Franchi and

Davis, P.E., is general manager with the Linda County Water District in Olivehurst, Calif.

Santoro, 2015; Paulsrud et al., 2014; Rusten and Odegaard, 2006), include:

1. Decreased electrical energy required for aeration (by approximately 15 to 30 percent) in secondary treatment because of reduced organic loading.

2. Increased gas energy production in the anaerobic digestion process (by 30 to 40 percent) resulting from the high organic energy content of the volatile suspended solids (VSS) removed and the increased volume of primary sludge sent to the anaerobic digesters.

3. Expanded secondary treatment capacity by reducing the organic loading upstream of the secondary process.

Figure 1.

Demonstration of cloth disk primary filter installation.

4. Reduction of footprint required for primary treatment by approximately 60 to 70 percent.

5. Reduced capital cost for primary and secondary treatment processes.

Although there are several technologies used to replace primary sedimentation facilities, it’s important to note that there are significant differences in the effluent quality, especially with respect to TSS concentration and particle size distribution. For example, there is no comparison between the effluent quality from technologies with pore sizes varying from 150 to 1,000 millimeters (mm)

Cloth Disk Primary Filter

With the enhanced removal of organic material achieved with the CDPF that has a small pore size, the amount of carbonaceous BOD5 that must be treated in the biological treatment process is reduced, which, in turn, results in a reduction in the energy requirements for aeration. The additional organic solids removed with the CDPF also result in greater digester gas production.

A definition sketch for the CDPF used in this study is shown in Figure 1. As shown,

that solidify at ambient temperatures) rise to the surface of the tank and heavy solids settle to the bottom. Floatable material is skimmed from the surface and settled solids are removed with suction headers. The flow of wastewater to be filtered is from the outside through the filter cloth to the inside of the filter cloth housing. The filtered effluent, collected in a header connected to one or more disks, is discharged to the effluent channel.

In effect, there are three active zones within the filter tank: scum zone, filtration zone, and solids settling zone. The filtration

and readily settable material is removed separately and does not pass through the filter media, thus avoiding the solidified grease and solids loading problems that have plagued other direct filtration systems.

Operationally, filterable solids that accumulate on the surface of the filter disks also serve as a secondary filter. As more filterable solids accumulate on the surface of the filter disks, the water level in the tank increases as the headloss through the filter cloth increases. When the liquid level rises to a predetermined setpoint (typically at 12 in.), a backwash cycle is initiated automatically. The filterable solids that accumulate on both sides of the disk filter are removed with a vacuum suction header, which is in contact with the filter cloth. The applied vacuum suction allows the filter fibers to extend into the backwash vacuum suction header, thereby permitting solids that have accumulated on and within the cloth filter to dislodge and be removed.

(Note that gaps in data during the reporting period reflect malfunctioning of the turbidimeter.)

The first full-scale CDPF system (Aqua-Aerobic Systems Inc., AquaPrime Filtration System) employing a fine pore cloth was installed at the Linda Wastewater Resource Recovery Facility (WRRF) located in Olivehurst, Calif. (Figure 2). Since start-

up in July 2017, the CDPF system has treated screened wastewater upstream of the secondary treatment process. Operation details of the CDPF system, monitoring and sampling procedures, and the approach used to assess the treatment and hydraulic performances of the CDPF system are discussed elsewhere (Caliskaner et al., 2020). Measured treatment performance data for the CDPF system are presented here to evaluate their impacts toward achieving netzero WRRFs.

Treatment Performance

The treatment performance of the CDPF was evaluated in terms of removals achieved for TSS, BOD5, chemical oxygen demand (COD), total kjeldahl nitrogen (TKN), and particle removal efficiency. Performance data from the full- and demonstration-scale CDPF installations were used to perform process simulations using BioWin 5.3. The simulations evaluated the impact of CDPF on downstream processes and energy benefits, including potential reduction in secondary treatment energy requirements and an increase in digester gas production. Results of the simulations are discussed further.

Total Suspended Solids Removal

The TSS removal data are presented in Table 1, based on laboratory measurements. Composite 24-hour samples were analyzed in the laboratory to assess the performance of the CDPF system for TSS removal. Influent TSS values ranged from 160 to 560 mg/L, with an average of 301 mg/L. The average removal performance for TSS was observed to be 83 percent (Table 1). The high TSS removal efficiency achieved by PF increases the volume of primary sludge sent to the anaerobic digesters, as compared to the primary sedimentation facilities. The daily variation in TSS removal over the duration of the test period is shown in Figure 3.

Process simulations using BioWin found that the CDPF resulted in a total sludge increase and biogas energy production increase of approximately 30 and 40 percent, respectively (Caliskaner et al., 2019). Reducing the amount of organic matter applied to the biological treatment process reduces the amount of carbon lost to the atmosphere during aerobic treatment (e.g., activated sludge) and the amount of waste sludge that must be processed. Thus, the total sludge that must be processed contains a much higher proportion of primary sludge, which is easier to digest and yields more

gas, as opposed to waste activated sludge (Bolzonella et al., 2005).

An important observation to be made from the data presented in Figure 3 is that, regardless of the influent variability, the TSS effluent concentration was very stable. This stability is important with respect to the performance of the biological treatment process and for the corresponding reduction in the energy requirements for treatment, as peak loadings are reduced.

Biochemical Oxygen Demand and Chemical Oxygen Demand

Treatment performance for BOD5 and COD is summarized In Table 1. Average removal efficiencies for BOD5 and COD were 58 and 57 percent, respectively, which are considerably higher as compared to conventional primary sedimentation. Due to the significant organic load reduction

upstream of the activated sludge process, the capacity of the secondary treatment processes was estimated to increase by approximately 20 percent. Further, by eliminating sudden peak solids and organic loadings to the activated sludge process, the stability of the secondary process is enhanced, leading to improved effluent quality and lower energy costs.

Total Kjeldahl Nitrogen Removal

As presented in Table 1, average TKN removal efficiency was observed to be 19 percent. Essentially, all of the TKN removal is associated with the removal of particulate solids.

Discussion of Full-Scale Primary Filtration System Performance

The primary goals of the CDPF

Florida Water Resources Journal • January 2023 25

technology development and demonstration project are to demonstrate long-term treatment performance and mechanical reliability, and to verify the process design and operational parameters for CDPF installations.

The CDPF process performance is compared to conventional primary sedimentation in the following section.

Treatment Performance

With respect to treatment, the following performance was achieved:

S TSS removal performance of CDPF was approximately 30 to 50 percent higher compared to conventional primary sedimentation.

S BOD5 and COD removal with CDPF was approximately 30 to 50 percent higher compared to conventional primary sedimentation.

S The resulting increase in biogas energy production has been estimated to be between 30 and 40 percent, based on BioWin simulations using treatment performance results from full- and pilotscale CDPF demonstrations (Caliskaner et al., 2019).

S Aeration power requirement in the downstream aerated activated sludge process is estimated to decrease by approximately 15 to 30 percent, depending on specific WRRF operating conditions. The corresponding capacity increase in secondary treatment processes is approximately 15 to 20 percent (Caliskaner et al., 2019).

S With CDPF, the footprint requirement is reduced by approximately 60 to 70 percent as compared to conventional primary clarifiers.

One of the big differences between the effluent from a CDPF installation and conventional primary sedimentation is that, regardless of the influent TSS loading, the effluent TSS concentration from the CDPF remained relatively constant (see Figure 3), as does the particle size distribution to be processed in the biological treatment process.

Verification of Cloth Disk Primary Filter Performance

To verify performance parameters for the CDPF technology, the results obtained from the full-scale CDPF system at Linda WRRF are compared with other demonstration projects, conducted at several demonstration sites across the United States (Table 2).

As seen in Table 2, CDPF removal performance was observed to be consistent from various pilot-, demonstration-, and full-scale projects.

Ongoing Technology Development and Demonstration Project

A three-and-a-half-year (2021-2025) technology research and demonstration project is underway at the WRRF to demonstrate the benefits and performance of three advanced primary technologies (APT) including CDPF, Microscreen, and compressible medium biofiltration, and three advanced secondary treatment (AST) technologies (membrane aerated bioreactor, aerobic granular sludge, and Microvi). The evaluation of the APT and AST systems is based on energy savings, capacity increase, and treatment performance.

To understand the impact of APT on secondary treatment and to have a comprehensive evaluation on the performance of the combined APT-AST configurations, four different process flow configurations are being demonstrated.

S Demonstration 1 is the baseline performance of primary clarifier combined with conventional secondary treatment.

S Demonstration 2 is to evaluate the treatment performance and economic benefits of enhanced secondary treatment downstream of APT technologies.

S Demonstration 3 is to evaluate the treatment performance of three AST technologies downstream of primary clarifier.

S Demonstration 4 is to evaluate a combined full-scale APT-AST system and quantify the benefits of advanced wastewater treatment.

Weld Well to End Well

Safety is a critical consideration for any welding project. Arc welding is a safe undertaking when proper precautions are taken, but if certain measures are ignored, welders (and those around them) face an array of hazards that can be potentially dangerous, including electric shock, respiratory hazards, eye and skin injuries, fire, explosions, and more.

To help keep welders safe, organizations such as the American Conference of Governmental Industrial Hygienists, American Welding Society, and Occupational Safety and Health Administration (OSHA) offer safety guidelines to help control, minimize, or help employers and workers avoid welding hazards.

Here are a few to review before beginning any welding project.

Eye Injuries

Welding and cutting operations are a major source of eye injury. Related accidents occur when proper personal protective equipment (PPE) is not worn. The most common eye injuries result from flash burn, metal flying into the eye, and particulates falling into the eye. The only measure that will prevent eye injury is the use of appropriate eyewear and shields. It’s also important not to wear contact lenses while welding or near where welding is taking place. Welding helmet sand filter plates are intended to help protect users from arc rays and from weld sparks and spatters that strike directly against the helmet. They are not intended to protect against slag chips, grinding fragments,

wire wheel bristles, and similar hazards that can ricochet under the helmet. Spectacles, goggles or other appropriate eye protection must also be worn to protect against these impact hazards.

When arc cutting and arc welding with an open arc, OSHA requires operators to use helmets or hand shields with filter lenses and cover plates. Nearby personnel viewing the arc must also be protected and the welder should always use a welding curtain or wall. Safety glasses with a shade 2 lens are recommended for general-purpose protection for viewers.

Skin Injuries

Injuries to the skin usually result from ultraviolet rays or from hot metal. The hot metal may be the material being worked on, or it may be part of the equipment. Unprotected skin is at risk for injury. In addition to burns, it’s easy for exposed skin to be cut during work with sharp metal. Proper safety shoes, clothing, and PPE will greatly reduce the chances of skin injury.

Respiratory Hazards

Without adequate ventilation, or when adequate PPE is not used, the threat of respiratory injury greatly increases. Before welding, the welder should know what the metal is and the potential effects of the fumes produced, which include carbon monoxide. Inhaling welding fumes or gas can produce

metal-fume fever, the symptoms of which include a metallic taste in the mouth, fatigue, nausea, and muscular and joint pain. Depending on the metal or alloy, the results can be fatal.

Adequate ventilation (natural, mechanical, or respiratory) must be provided for all welding, cutting, brazing, and related operations, which means enough ventilation so that a person’s exposure to hazardous concentrations of airborne contaminants is maintained below the level set by federal standards.

Adequate ventilation depends on the following factors:

S Volume and configuration of the space where the welding operations occur

S Number and type of operations that are generating contaminants

S Natural air flow rate where operations are taking place

S Location of the breathing zones for the welder and other workers in relation to contaminants or sources

Natural ventilation is considered sufficient for welding and brazing operations if the work area meets these requirements:

S Space of more than 10,000 square feet is provided per welder

S A ceiling height of more than 16 feet

S Welding is not done in a confined space

S Welding space does not contain partitions, balconies, or structured barriers that obstruct cross ventilation

“Spotlight on Safety” column.

Whenever feasible, local and area ventilation systems should be used to remove harmful fumes and gases; however, in many cases, engineering controls alone cannot reduce exposure levels adequately. In such cases, it may be appropriate to use respirators. For most welding applications, an array of respirator options exist that offer specific benefits.

Electric Shock

Electric shock is one of the most serious and immediate risks facing a welder. It can lead to severe injury or death, either from the shock itself or from a fall caused by the reaction to a shock.

Electric shock occurs when welders touch two metal objects that have a voltage between them, thereby inserting themselves into the electrical circuit. For instance, if a worker holds a bare wire in one hand and a second bare wire with the other, an electric current will pass through that wire and through the welding operator, causing an electric shock. Be aware that the higher the voltage, the higher the current, and thus, the higher the risk for the electric shock to result in injury or death.

The most common type of electric shock is secondary voltage shock from an arc welding circuit, which ranges from 20 to 100 volts. Bear in mind that even a shock of 50 volts or less can be enough to injure or kill an operator, depending on the conditions. Due to its constant change in polarity, alternating current (AC) voltage is more likely to stop the heart than direct current (DC). It’s also more likely to make the person holding the wire unable to let go.

Be sure all electrical equipment is properly installed, inspected, operated, and maintained. Before use, consider the following:

S Placement of welding machines

S Placement of cables

S Load protection

S Use of electrodes and holders

Fire Hazard

Welding and cutting should be done in designated areas that are free of flammable materials or conditions favorable to fire or explosion. If your utility has a hot-work permit program, make sure to follow its requirements. Before and during the welding operation, the welder and safety watch should do the following:

S Inspect the area for flammable and combustible material before welding or cutting begins

S Cover cracks or floor openings

S Have fire extinguishers on hand

During welding, constantly watch for fires between walls, on opposite sides of metal partitions, or in any concealed place.

Personal Protective Equipment

Your utility’s PPE helps to keep welding operators free from injury, such as burns, which are the most common welding injury, and exposure to arc rays. The right PPE allows for freedom of movement, while still providing adequate protection from welding hazards.

Thanks to their durability and fire resistance, leather and flame-resistant cotton clothing is recommended in welding environments. This is because synthetic material, such as polyester or rayon, will melt when exposed to extreme heat. Welding leathers are especially recommended when welding out of position, such as applications that require vertical or overhead welding.

Avoid rolling up sleeves or pant cuffs because sparks or hot metal can deposit in the folds and may burn through the material. Keep pants over the top of work boots—don't tuck them in. Leather boots with 6- to 8-inch ankle coverage are the best foot protection. Metatarsal guards over the shoelaces can protect a welder's feet from falling objects and sparks.

Confined Spaces

Because of the small size and questionable atmosphere in most confined spaces, welding and cutting in such spaces requires very serious thought and planning.

There are very specific regulations from OSHA when it comes to welding in confined spaces. If the area can’t get proper ventilation without blocking the means of entry, welders must use respirators and be in constant communication with a coworker on the outside. Another OSHA rule states that safety belts, lifelines, and preplanned rescue procedures are required if the welding work has to happen in a space with a very small entryway (like manholes).

Always check the following before working in a confined space:

S Make sure there isn’t any equipment blocking the exit

S Test the air for toxic gases before entering the workspace

S Remove all hazardous materials

S Keep vents open and making sure valves are tight and leak-free

S Have the means to immediately shut off gases, fuel, and power from inside the space if possible

Fire and Explosions

The welding arc creates extreme temperatures and may pose a significant fire and explosion hazard if safe practices are not followed. While the welding arc may reach temperatures of 10,000°F, the real danger is not from the arc itself, but rather the intense heat near the arc and the heat, sparks, and spatter created by the arc. This spatter can reach up to 35 feet away from the welding space.

To prevent fires, before beginning to weld inspect the work area for any flammable materials and remove them. Flammable materials are comprised of three categories:

S Liquid, such as gasoline, oil, and paint

S Solid, such as wood, cardboard, and paper

S Gas, including acetylene, propane, and hydrogen

Other Safety Considerations

In any welding situation, the operators should pay close attention to safety information on the products being used and the safety data sheets provided by the manufacturer, and they should work with their employer and coworkers to follow appropriate safe practices for their workplace.

Good common sense is key to a safe workplace when welding. If opening cans of electrode, keep your hands away from sharp edges. Remove clutter and debris from the welding area to prevent tripping or falling, and never use broken or damaged equipment or PPE.

By following these safety practices, operators can stay safe and alive and keep production moving with no lost-time accidents.

Wastewater Treatment Creates

High-Quality Water for Florida

and to our “Best of the Best” Tap Water Taste Contest winner, Citrus County Utilities, which will represent us at the 2023 AWWA Annual Conference and Exposition (ACE23) in Toronto!

Water Comes From Many Sources

appy New Year! As a welcome start to 2023, I’d like to first thank section staff and the Manufacturers/Associates Council (MAC) for once again executing an exquisite 2022 Fall Conference, with record attendance and participation from our members. Congratulations to all of the award winners

As the recently elected chair of FSAWWA, I would like to thank everyone for their faith and support. This is my first article for the magazine and it’s an honor to be able to share ideas and thoughts regarding the state of the water industry. The section and our sister professional organizations have strived to show the value of water, and we recognize our role as stewards. We have long since realized that water, in all its forms, is a precious resource. Florida, in particular, has been a leader in recognizing this and developing solutions to maximizing the benefits of water.

Our traditional water supply sources have primarily come from groundwater wells, with surface water supplies being the second largest water source. As the state’s population grows, our traditional resources have been strained as we strive to protect the environment. Over the past few decades, we have even looked to brackish water and ocean resources to supplement the state’s water supply. Conservation programs have shown widespread adoption to reduce customer demands and extend the availability of water. New technologies, in conjunction with old and new ideas on water, have helped drive solutions such as stormwater capture, reclaimed water distribution expansion, and potable reuse.

As the January issue is focused on wastewater treatment, this should be recognized as a vital component to solving the water supply issues around Florida. At many wastewater treatment facilities throughout the state, the effluent produced is of high quality and can be used as public access reuse water. This effluent has the ability to protect water supplies from saltwater intrusion, offset potable water demand through irrigation and gray water use, restore wetlands and other environmentally sensitive areas, or someday soon, be used as a supplemental potable water supply source through indirect or direct potable reuse.

Whichever use is the most beneficial for your community, thoughtful consideration is to be given to net benefits and costs. We truly live in a “one water” environment as we take the water from the environment, use it and produce wastewater, capture wastewater and stormwater, and then reintroduce the clean water back to the environment for us to use again and again.

Get and Stay Involved

As the new year begins, I encourage you to start and hopefully continue active communications with your political representatives. Section committees are conducting meetings and have started to debate regulations and funding opportunities. In order to implement the technologies and planning initiatives that are required for us to continue to manage this precious resource, we must work with our representatives to help prioritize funding resources for water.

We at FSAWWA want to wish a Happy New Year to you all!

From Stormwater to Wastewater Treatment

The Water Environment Federation (WEF) has been asking members to share their water stories, mainly relating how they

ended up working in water. As part of its new strategic plan, WEF is working to amplify the stories of water to grow, strengthen, and diversify the water community. Members are encouraged to share their water stories with WEF and follow #WEFwaterstories on social media.

My Wastewater Treatment Story

In my case, I stumbled into wastewater treatment through my stormwater background. One could say that it all started back when I was

attending Auburn University. While in school I worked for a small consulting firm in Columbus, Ga., about a 45-minute drive from Auburn. We primarily did subdivision design work, and I discovered that I really liked to work on stormwater systems.

After graduating from Auburn in 1994, I began to work with the Florida Department of Transportation in Bartow. Once I completed the 18-month-long professional engineer trainee program, I began working in the stormwater group. A few years later, I returned to a consulting firm doing stormwater design for developments in north Florida. This work eventually led into managing site development projects at another firm where one engineer handled the utilities design for all projects.

One day he surprised us and went to work for one of our clients, so I needed to jump into utilities design for my projects, and I eventually became a utility liaison between the City of Tallahassee and my firm.

Over time, the city managed to recruit me to join its team. Honestly, I resisted at first because I was afraid of being bored of working for a government. Ha—was I ever wrong in that regard!

My work at the city started off with water and sewer design work; however, the wastewater treatment facility had some stormwater flooding

members and I got to know each other, and they started to ask for assistance with other site issues as I showed interest in the workings of the facility.

Unknowingly to me, in 2005 a request was made to the utility director by Darby Dressel, the wastewater treatment supervisor, to reassign me to the wastewater treatment facility. From there I served as the project manager for the multiyear facility upgrade, which lead to my becoming the operations supervisor, followed by returning to the engineering office to manage the wastewater treatment capital improvement program.

I feel very fortunate that my water story turned into a wastewater treatment story. As I wind down my time at the city, I am glad to share my knowledge with the next generation of water storytellers.

Wastewater Process Committee and Upcoming Seminars

There are several ways to get more involved or to learn more about wastewater treatment. For example, WEF is planning an Innovations in Process Engineering Conference, scheduled for June 6-9, 2023, in Portland, Ore. If interested, abstracts, session proposals, and workshop

proposals can be submitted until Jan. 13, 2023. More information is available on the conference webpage at www.wef.org/events/conferences/ upcoming-conferences/ProcessEngineering.

For a Florida focus, the FWEA Wastewater Process Committee is a great source. The next Wastewater Process Seminar will take place on

Jan. 24, 2023. This 10th annual seminar will take place in two locations! The presenters will be located in Pompano Beach, while an in-person remote telecast is available in St. Augustine.

First Coast Chapter: Getting Bigger and Better Every Year

First Coast Chapter is growing fast and looking for volunteers and sponsors

Overview of First Coast Events

The First Coast Chapter holds several social and technical events jointly with FSAWWA Region II. The year kicked off with the Sporting Clays event, which is held annually on Presidents’ Day. This event was held at the Saltwaters Shooting Club in St. Augustine and was accompanied by an amazing barbeque lunch and raffle prizes.

The chapter hosts a spring luncheon in conjunction with the FSAWWA Region II Drop Savers Poster Contest and Best Tasting Drinking Water Contest. In 2022, this event, at the San Jose Country Club, was very well-attended. Following the luncheon was the Don Maurer Putting Tournament held at TPC Sawgrass. The proceeds from this event go toward the Don Maurer Scholarship Fund at the University of Florida. This is one of the flagship events of the chapter and has seen over 130 participants.

The annual golf tournament at the end of summer was another flagship event, held at the St. Johns Golf and Country Club. Other summer events included the annual fishing tournament and young professionals and veterans networking events.

Last but not the least, we ended the year with a holiday social and toy drive. This is a member appreciation event to acknowledge all members, volunteers, and sponsors; take a look back on the previous year; and get energized for the upcoming year. This event, at Aardwolf Brewing in Jacksonville, was well-attended and included students from our thriving student chapters at University of Florida and University of North Florida.

Show Your Support!

We are continuously seeking volunteers and sponsors to join us in the continued growth of the First Coast Chapter and the numerous events we host year round. If you would like more information about getting involved, either as an individual or with company support, please feel to reach out to the chair of the chapter, Dave Rasmussen, at DRasmussen@ardurra.com.

Asset Management for Water and Wastewater Treatment Systems: Local Officials Primer

Aging infrastructure, projected lower growth in the economy, and increasingly sophisticated demands from regulators and other stakeholders are creating a perfect storm of challenges for water and wastewater utilities, placing conventional maintenance and capital planning practices under pressure.

Many utilities are looking to recent developments in asset management best practices. The essence of this is the value realization from assets—ensuring that the right things are being done right, and that these activities support an organization’s strategic objectives. But how does your organization define value, and where should you begin?

This article is primarily intended for local officials who are directly or indirectly involved in decisions affecting water and wastewater utility systems.

Asset Management

Asset management is maintaining a desired level of service for what you want your assets to provide at the lowest life cycle cost. Lowest life cycle cost refers to the best appropriate cost for rehabilitating, repairing, or replacing an asset. Asset management is implemented through an asset management program and typically includes a written asset management plan.

Water and wastewater systems need asset management to:

S Address aging water infrastructure assets before they fail.

S Keep assets productive, and not allow them to become disruptive liabilities.

S Treat all decisions as investment decisions to maximize limited financial resources.

S Make costs transparent to support financial decisions.

Asset management requires: Continued on page 44

Florida Water Resources Journal • January 2023 43

S Support and involvement of local officials who have the authority and willingness to commit public resources and personnel to maintain community assets.

S A commitment of time and money to make cost-effective asset decisions (spending some money in the short term to save more money over the long term).

S A team made up of key decision makers.

Improving Service and Maintaining Infrastructure Through Asset Management

A sustainable water service delivers safe, clean water to the satisfaction of its customers, while managing infrastructure assets to maximize their useful life. An asset management plan will help you “tell the story” of water system assets to the community in a way that is understandable. Small systems that have simple asset management plans can benefit as much as large systems that have complex plans.

Asset management will enable your system to:

S Have more efficient and focused operations.

S Choose capital projects that meet the system’s true needs.

S Base rates on sound operational decisions.

S Improve its financial health.

S Reduce environmental violations due to failed or poorly performing assets.

S Improve the security and safety of infrastructure assets.

The Five Core Questions for Asset Management

A good starting point for asset management for any system is a list of five core framework questions, which walk you through all of the major activities associated with asset management.

What is the current state of my system’s assets?

Your water system’s assets are part of your community’s total assets. A decline in the value of your infrastructure indicates insufficient funding of asset management.

What is my required “sustainable” level of service?

Knowing your required “sustainable” level of service will help you implement an asset management program and communicate to stakeholders what you are doing. The required level of service is the basis for justifying your user rates.

Which assets are critical to sustained performance?

Identifying critical assets will help you make decisions about resource allocation and about maintaining or improving your sustainable level of service.

What are my life cycle costs?

Knowing the answer to this question will help your system move from a passive “fix it when it breaks” posture to an active program of preventive maintenance and timely asset replacement.

What is my best long-term financing strategy?

Knowing the full economic costs and revenues generated by your water system will help determine the system’s financial forecast. This forecast can then provide needed information in making decisions regarding long-term funding strategy.

Accounting for Your Assets

The Governmental Accounting Standards Board’s Statement #34 (GASB 34) revises several accounting and financial reporting practices for state and local governmental entities, including publicly owned water systems. If your water system is publicly owned, you will need to follow GASB 34 requirements to obtain a “clean opinion” (i.e.,

a good credit rating) from an auditor. Without a clean opinion, you may face higher interest rates on loans and bonds and may be more closely scrutinized by regulators and public officials.

Following GASB 34 standards will require publicly owned water systems to report the value of infrastructure assets and the cost of deferred maintenance. An accurate and up-to-date asset management plan will help you comply with this requirement.

Key Role for Local Officials: Building Community Support

Successfully implementing an asset management program means overcoming potential barriers by including the community in the process. Local officials are key players in successful asset management programs because they are uniquely positioned to address these challenges.

Barriers to implementing an asset management program may include:

S Expecting to see immediate results.

S Changing from a focus on operations to a focus on assets.

S Paying for short-term costs to achieve longterm savings.

S Reconciling a short-term focus (e.g., rate increases) with a long-term view of system sustainability.

These barriers can be overcome by building community support for asset management’s emphasis on planning as a means for costeffective infrastructure investment. An asset management plan is an effective way to communicate your strategy and work.

In order for your system to gain community support, your customers should:

S Understand what you do.

S Believe that what you do has value.

S See that the way you work meets the agreed-upon level of service.

Asset management helps you:

S Share information with your customers.

S Describe the risks of not maintaining system components.

S Communicate your system’s requirements.

S Justify rehabilitation, repair, and replacement project priorities.

S Justify your long-term financial plan to the public.

Implementing an asset management program will allow you to start having sustainable water service that will maximize the useful life of your assets, be financially selfsupporting, and protect public health and the environment. S

The Econoline pressure transmitter from Keller is built for next-level performance at an optimum price point. It combines a proven media-isolated, piezoresistive silicon sensor with contemporary signal conditioning electronics to provide a compact pressure transmitter with class-leading total error band accuracy. In addition, the Econoline provides outstanding performance under harsh environmental conditions, including those with high levels of electromagnetic radiation, both conducted and radiated. The Econoline provides trouble-free service and sufficient accuracy for almost any application, including those involving aggressive media and/or high levels of electromagnetic interference and where small size, low weight, and reasonable cost are required. The modular design of the Econoline provides maximum versatility for customer specific applications and is produced using modern manufacturing methods. It allows for short lead times, which negates the need for the user to maintain extra inventory onsite. (www.kelleramerica.com)


treatment effluents. The basic sensing element used in the total chlorine monitor is a threeelectrode amperometric membrane sensor that measures chlorine directly. The chlorine measurement does not alter the sample or add any chemicals to the sample stream, so the water flow can return to the system, if desired. This direct measuring system does not require the addition of chemical reagents to measure total chlorine, which means that the unit can be deployed for months without having to change anything; usually, reagents typically need to be maintained on a monthly basis.

In addition to total chlorine measurement, the Q46/79PR is also available with an optional pH input that provides a two-parameter monitoring system. It can be supplied with sample flow controls mounted to a PVC back plate ready to mount; simply connect the power, water sample, and analog/ relay outputs. Systems are available with or without a flow switch for remote indication of loss of sample.

as a tried-and-true method for water and wastewater treatment. That doesn’t mean the technology can’t be upgraded, and the Leopold Texler lamella clarifier from Xylem is a great example, as its lamellae are made from a recyclable, durable, high-density polyethylene geotextile material that reduces service and maintenance requirements, while cutting solids by more than 80 percent.

The lamella plates typically found in clarifiers are made from heavy stainless steel plates, which require extensive support structures and significant capital investment. When exposed to sunlight, steel reflects ultraviolet rays and promotes algae growth in the clarifier, reducing the clarification performance and requiring regular, manual cleaning. The repellent and flexible nature of the geotextile prevents sludge accumulation on the lamella sheets, which reduces the need for regular cleaning.

The biological activity enhancer (BAE) from Prodex is an organic liquid formula for use in aerobic and anaerobic environments to improve operational efficiency and maximize renewable energy production. As the green component to the engineered infrastructure, it provides plants with a lowcost biostimulant for existing microbes, increasing activity and populations to give the plant the best biology possible. Wastewater treatment plants can use it to boost biogas production, convert food waste to energy, and help remove nitrogen, and it can be used in maintenance dosage and emergency use. It reduces operational costs, such as hauling, chemicals, and energy; enhances plant operational efficiency and stability; improves solids handling and sludge settling; and accelerates recovery after plant upsets. By maximizing the microbial workforce, it helps the industry work toward cleaner water resources and a greener energy supply. (www.prodexproducts.com)

RThe Model Q46H/79PR Total Chlorine Measurement System from Analytical Technology (a Badger Meter brand) is a highly versatile online monitoring system designed for the continuous measurement of total chlorine in solution. It’s well suited for potable water systems, water reuse systems, cooling towers, and monitoring wastewater

RIts simplicity in design means less investment in replacement parts, and because it takes less manpower to operate, the overall operating cost is very manageable. The addition of features, like a pH input to its basic functionality, makes it all the more valuable in water and wastewater applications. (www.badgermeter.com)

The Davit Cranes from Patterson, available in ½-ton and 1-ton capacities, can give utility operations a lift. The lowmaintenance, easy-to-assemble design offers adequate reach to accommodate lifting large loads within tight spaces, and a boom that can be adjusted to nearly 45 degrees to allow for clearance over obstructions, such as handrails. Built for durability, it comes standard with a hot-dipped galvanized finish and stainless steel hardware to prevent rust and corrosion in wet work environments. Following Patterson’s tradition of safetyfocused innovation, the product features a reliable brake to keep loads in position without creeping. For over 160 years the company has been a trusted supplier of winches, rigging, fittings, and custom products for lifting applications. The cranes are made in the United States and deliver on the company’s promise of helping businesses run safer, easier, and faster. (www. pattersonmfg.com) R

For centuries, sedimentation has served

Lamella sheets are installed at an inclined 55-degree angle. Solids settle as the water travels upward between the lamella sheets and flows through trough covers, featuring an integrated v-notch weir, resulting in even distribution of flow throughout the clarifier.

RThe inclined plate arrangement of the system allows for an increase in the clarification area and allows for higher surface overflow rates, reducing the required basin dimensions by up to 80 percent for new builds and allowing more than 100 percent increase in flow within existing sedimentation basins. The geotextile material has been proven in similar applications to last over 20 years. The width of the lamella sheets can be adapted to optimize the use of existing basins. As a result, water treatment capacity of existing rectangular clarification systems can be increased by up to 100 percent, with an over 80 percent reduction in solids and turbidity values reaching levels less than 1 NTU. The product’s modular design allows for easy maintenance as each lamella sheet can be easily removed independently. The flexible design allows for cost-effective retrofitting of existing rectangular basins, which significantly reduces the overall construction costs, while significantly increasing flow capacity.
