A Case for Regionalization

Water and wastewater services are needed in every community in order to sustain it, but some communities need more assistance in order for their water utility to thrive. Many rural areas face challenges like meeting strict regulations while still providing affordable services to users. As technology becomes more sophisticated, the need to purchase new, expensive equipment becomes unavoidable for small utilities that often do not have the funding or resources needed. This is when regionalization can really benefit utilities and their customers alike.

Regionalization helps two or more water systems to leverage and combine resources, equipment, personnel, and even physical plants. According to U.S. EPA, “the main benefit of regionalization is that it pools individual resources of two or more water systems to obtain services or facilities that one or both systems may not have been capable of obtaining by themselves.”

In the Rural Community Assistance Partnership's (RCAP's) 2021 report: Affordability and Capability Issues of Small Water and Wastewaters Systems: A Case for Regionalization of Small Systems, they feature a case study that shows a successful model for regionalization from the Greater Cincinnati Water Works (GCWW) in southwest Ohio. GCWW offers the smaller water systems in the area much assistance in the form of: lab testing services, billing services, call center operation, a source of project financing, construction management services, engineering services, and emergency help when needed. 

RCAP also released a report titled: Regionalization: RCAP’s Recommendations for Water and Wastewater Policy which contained 22 recommendations that should be integrated into policy decision-making. The research featured in this report was unveiled in a webinar that also focused on the experiences of five different states: California, Florida, Ohio, Pennsylvania, and Texas, who spoke about what they have put in place to help support the various forms of regionalization.

PFAS Treatment: What We Know in 2023

PFAS (formally known as per- and polyfluoroalkyl substances) are widely used, long lasting chemicals that break down very slowly over time. They break down so slowly that they end up in water, air, fish, and soil all over the world, and trace amounts have even been detected in human blood. Scientific studies have shown that exposure to some PFAS in the environment may be linked to harmful health effects in humans and animals, but we do not know to what extent they may affect us.

PFAS possess chemical properties that mean traditional drinking water treatment technologies are not able to remove them. Researchers have been working on a variety of treatment technologies to determine which methods work best to remove PFAS from drinking water. Some of the most successful methods include: activated carbon adsorption, ion exchange resins, and high-pressure membranes. 

Granular activated carbon (GAC) adsorption: GAC has been shown to effectively remove PFAS from drinking water when it is used in a flow through filter mode after particulates have already been removed. According to EPA researcher Thomas Speth, this method can be extremely effective “depending on the type of carbon used, the depth of the bed of carbon, flow rate of the water, the specific PFAS you need to remove, temperature, and the degree and type of organic matter as well as other contaminants, or constituents, in the water.”

Ion exchange resins: Negatively charged ions of PFAS are attracted to positively charged anion resins. Anion exchange resins (AER) have proved to have a high capacity for many PFAS; but this method can be more expensive than GAC. The most promising version of this method is an AER in a single use mode, followed by incineration of the resin. This technology has no contaminant waste stream to treat or dispose due to the lack of need for resin regeneration.

High-pressure membranes: Research shows that membranes, such as nanofiltration or reverse osmosis, are typically more than 90 percent effective at removing a wide range of PFAS. However, these methods generate a large volume of high-strength waste stream which can be difficult to treat or dispose of for a water system. This technology may be better suited for a homeowner since it would generate a much smaller volume of waste.

EPA Mandates Cybersecurity Reporting for the Water Sector

Public water systems are increasingly at risk from cyberattacks that threaten public health. U.S. EPA has issued new guidance that states are required to evaluate and report on cybersecurity threats for systems that use industrial control systems or other operational technology.

“Cyberattacks against critical infrastructure facilities, including drinking water systems, are increasing, and public water systems are vulnerable," said EPA Assistant Administrator Radhika Fox. “Cyberattacks have the potential to contaminate drinking water.”

This expectation is outlined in a memo that interprets sanitary survey requirements, accompanied by a detailed guidance document aimed at state programs and technical assistance providers. It was released as part of the Biden administration's updated National Cybersecurity Strategy. 

U.S. EPA offers resources that can help water systems understand and address cyber vulnerabilities including this video on basic cybersecurity concepts that can be used by water systems as a part of an annual cybersecurity training program. Our database on WaterOperator.org also has resources on this topic, including this 56-page guide from WaterISAC on cybersecurity best practices to reduce exploitable weaknesses and attacks.

The Impact of Climate Change on Massachusetts Septic Systems

Climate Change + Population Increase = Imbalance in the Waterways of Cape Cod, Massachusetts. 

The old septic systems used by about 95% of the growing population of Cape Cod are contributing to rising nitrogen and phosphorus levels in the waterways which are slowly warming due to climate change. Septic systems are a great option in places where homes are too spread out to justify sewers and water treatment plants but they don’t filter out the nitrogen and phosphorus that ends up seeping into groundwater. When nutrients like nitrogen and phosphorus runoff into the water, they act as a fertilizer for bacteria and algae. This combination of factors has resulted in an “explosion” of blue-green algae to take over the Cape and wreak havoc on the ecosystem.

After several lawsuits filed by environmentalists, the state of Massachusetts has proposed that local communities are required to fix the problem within 20 years. This has created some pushback from the community of Mashpee, MA that has already started installing a sewer system, the construction of which was projected to be spread out over 25 years. If the proposed rule is enforced, that would force the community to move faster and find a way to cover the huge cost of construction. This raises the issue of cost in general since sewers and water treatment plants are extremely expensive for the community and new septic systems can be a huge expense to the individual homeowners in the area, many of whom are retired and living on fixed incomes.

How this plays out in Massachusetts will be viewed by other states in the future as they seek to address similar surface water quality issues in areas with a high density of decentralized wastewater treatment.

Hurricane Preparedness for Wastewater Facilities

As Hurricane Ian left swaths of Florida without water and wastewater services at the end of September, the New York Times was already reporting on potential environmental impacts of the storm hitting South Carolina. Beyond the acute hazards of exposure to untreated wastewater, the biggest concern in hurricane-impacted areas is nutrient pollution and the potential for harmful algal blooms.

As extreme weather events impact larger stretches of the country, the water sector (including regional watershed protection entities) will need to anticipate greater consequences in the emergency response planning process. Florida DEP's Hurricane Preparedness for Domestic Wastewater Facilities and FEMA's Hurricane and Flood Mitigation Handbook for Public Facilities offer some helpful recommendations.

FEMA divides its recommended (primarily anticipatory) mitigation strategies into four categories: elevate or relocate, protect or divert, floodproof, provide redundant systems. The fact sheet identifies which of these strategies are appropriate for each major component of a wastewater facility. For example, installing "backflow prevention devices such as valves on lines that flow into the lift station and emergency overflow lines" is an option for floodproofing a lift station.

FEMA also provides a similar framework for drinking water systems.

Florida DEP's suggestions for before and after a hurricane can provide an update to an existing baseline checklist, particularly for minimizing these concerning downstream impacts. For example, it is recommended to "drain wastewater holding ponds as completely as practical after receiving a hurricane warning" as well as ensure that biosolids for land application have been "spread or stored in a secure manner."

With the frequency and severity of hurricanes and other extreme weather events increasing, facilities may need to adopt new strategies to prevent costly cleanup efforts and even legal battles.
