    PFAS Regulation at Crossroads With EPA Litigation

    By
    Melissa Diehl
    -

    The recent filing of the American Water Works Association (AWWA) and the Association of Metropolitan Water Agencies (AMWA)’s opening brief in the case against the EPA’s PFAS drinking water regulation marks a significant step in the ongoing debate over the balance between public health protection and the practical implementation of environmental regulations. Let’s take a deep dive into the key arguments presented by the two organizations, explore the broader implications of the PFAS rule, and offer insights into potential avenues for resolution. 

    A Closer Look at the AWWA-AMWA Arguments 

    At the heart of the AWWA-AMWA statement is a contention that the EPA’s PFAS rule deviated from the established procedures outlined in the Safe Drinking Water Act. The organizations argue that the EPA’s accelerated timeline, limited opportunities for public comment, and use of a novel equation for PFAS standards undermine the scientific rigor and transparency required for effective regulation. 

    Specifically, the AWWA and AMWA point to the following shortcomings in the EPA’s approach: 

    • Truncated Rulemaking Process: The organizations contend that the EPA’s decision to expedite the rulemaking process limited the time available for thorough scientific evaluation and public input. They argue that a more deliberate approach would have allowed for a more comprehensive assessment of the risks posed by PFAS and the potential impacts of the regulation on water utilities and consumers. 
    • Curtailed Public Comment: The AWWA and AMWA argue that the EPA did not provide sufficient opportunities for stakeholders to express their concerns and offer alternative approaches. They contend that a more open and transparent process would have allowed for a wider range of perspectives to be considered, potentially leading to a more effective and equitable regulation. 
    • Novel Equation for PFAS Standards: The organizations criticize the EPA’s use of a novel equation rather than a clearly defined measurement as a standard for certain PFAS, arguing that this approach lacks scientific precedent and may not accurately reflect the risks posed by these contaminants. They contend that a more established and well-validated approach would have provided greater certainty and confidence in the regulatory standards. 

    Implications of the PFAS Rule 

    The outcome of the AWWA-AMWA case could have far-reaching implications for both public health and the water industry. If the court upholds the EPA’s rule, it could set a precedent for future regulatory actions, potentially leading to more aggressive and less flexible approaches to addressing emerging contaminants. This could place a significant burden on water utilities, which may struggle to meet the new standards in a timely and cost-effective manner. 

    On the other hand, a ruling in favor of the AWWA and AMWA could force the EPA to reconsider its approach and adopt a more deliberative and science-based process. This could lead to more effective and equitable regulations that better balance the need to protect public health with the practical realities of implementation. 

    Potential Avenues for Resolution 

    Beyond the legal proceedings, there are several potential avenues for resolving the ongoing PFAS controversy. One option is for the EPA to engage in a more collaborative dialogue with stakeholders, including water utilities, environmental groups, and industry representatives, to develop a consensus-based approach to PFAS regulation. This could involve establishing a working group or task force to identify and address the key challenges and opportunities associated with PFAS management. 

    Another possibility is for Congress to provide additional guidance or funding to support PFAS research and remediation efforts. By investing in scientific research, Congress could help to improve our understanding of the risks posed by PFAS and develop more effective and efficient mitigation strategies. 

    Finally, it is essential to consider the role of technology and innovation in addressing the PFAS challenge. By investing in new technologies for PFAS detection, removal, and destruction, we may be able to develop more effective and sustainable solutions to this pressing environmental issue. 

    The AWWA-AMWA statement on the EPA’s PFAS rule highlights the complex challenges associated with regulating emerging contaminants. While the organizations’ arguments raise valid concerns about the EPA’s approach, it is also essential to consider the urgent need to protect public health from the potential risks posed by PFAS. Ultimately, a resolution to this issue will likely require a balance between scientific rigor, public input, and the practical realities of implementing effective environmental regulations.

    Water utilities are on a tight deadline as the Environmental Protection Agency (EPA) prepares to enforce the Lead and Copper Rule Revisions (LCRR) by October 16, 2024. These revisions are designed to ensure the safety of drinking water and reduce lead exposure in communities across the United States. With six months left, it’s crucial to understand the key requirements and take necessary steps to comply with the rule. The LCRR builds on the original Lead and Copper Rule (LCR), established in 1991 to control the presence of lead and copper in drinking water.

    The updated version, released in 2022, introduces significant changes aimed at better protecting communities from lead contamination. These changes were prompted, in part, by the Flint water crisis, where thousands of residents were exposed to lead poisoning from April 2014 to October 2015. The LCRR includes stricter requirements, expanded testing protocols, and mandatory lead service line replacement for many water systems.

    Under the LCRR, public water systems must submit a comprehensive inventory of service line materials, identifying lead lines, galvanized lines requiring replacement, and unknown materials by the compliance deadline. This inventory is a critical step toward meeting regulatory requirements and mitigating lead exposure. The guidance provided by the EPA emphasizes the importance of transparency and communication with the public regarding the location and condition of lead service lines.

    Additionally, the LCRR introduces new public notification requirements. In the event of a Lead Action Level exceedance, communitywide public notification must occur within 24 hours. This requirement underscores the urgency of addressing lead contamination and maintaining public trust. Stephen Estes-Smargiassi, chair of the American Water Works Association’s (AWWA) Lead and Copper Rule Advisory Committee, advises water utilities to proactively engage with public officials, media, and other stakeholders before starting the sampling process to avoid surprises and ensure clear communication.

    The EPA has released several resources to help water systems comply with the LCRR. The Guidance for Developing and Maintaining a Service Line Inventory provides best practices, a template for creating inventories, and case studies to assist water systems in meeting the October 16 deadline. The Small Entity Compliance Guide, released in June 2023, is tailored to support small community and non-transient non-community water systems. Additionally, the EPA has hosted webinars to educate professionals on the revised rule and funding opportunities through programs like the Drinking Water State Revolving Fund (DWSRF) and the Bipartisan Infrastructure Law (BIL).

    With six months remaining, water treatment professionals should focus on several key actions to ensure compliance with the LCRR:

    1.       Develop a Comprehensive Service Line Inventory: This step involves identifying all lead and galvanized lines and creating a plan for replacement. The inventory must be submitted by October 16, 2024.

    2.       Communicate with Stakeholders: Proactive communication with public officials, health departments, and community members is essential. Ensure that everyone is aware of the new requirements and the steps being taken to comply with the LCRR.

    3.       Prepare for Public Notification Requirements: Establish a process for communitywide public notification within 24 hours of a Lead Action Level exceedance. This requires coordination with media outlets, public officials, and other stakeholders.

    4.       Stay Informed and Utilize Available Resources: The EPA provides extensive guidance and resources to support compliance efforts. Take advantage of webinars, templates, and other materials to ensure compliance.

    The clock is ticking, so it’s crucial to act now to ensure compliance by October 16, 2024.

    Melissa Diehl
    -

    In response to increasing cyber threats, the Environmental Protection Agency (EPA) has issued a critical warning to water utilities across the nation, revealing substantial gaps in cybersecurity compliance. According to the EPA’s recent enforcement alert, more than 70% of inspected water systems fail to meet essential security standards mandated by the Safe Drinking Water Act (SDWA). Common deficiencies include the use of default passwords and a lack of multi-factor authentication.

    A Growing Threat

    Cyber-attacks targeting water systems are on the rise. Notable incidents include Russian hacktivists disrupting water systems in Texas and Iranian-linked “CyberAv3ngers” defacing U.S. water infrastructure equipment. These attacks underscore the sector’s vulnerability and the urgent need for enhanced cybersecurity measures.

    EPA’s Increased Enforcement Measures

    To address these threats, the EPA is ramping up inspections and enforcement actions. Deputy Administrator Janet McCabe emphasized the agency’s commitment to protecting the nation’s drinking water from cyberattacks. The EPA’s plan includes:

    City Water Contamination

    Most water treatment professionals are used to the day-to-day analysis of water and maintenance that comes with the job. Howbeit, not all are prepared for a drinking water contamination incident such as E.coli. Is your team ready to respond when an emergency strikes?

    Unfortunately, this topic hits close to home for me. As a resident of Tyler and customer of TWU, I was quick to learn about a boil notice issued by the City of Tyler for E.coli contamination, and of course, was mildly horrified. The boil notice didn’t last long, though; the city lifted it the following day at 11 am. After talking with other residents and customers of TWU, to my surprise, this was not the first time the city has had water quality issues. Feeling concerned, I reached out to the City and asked if it was normal after E.coli detection in a water sample to only have a 24-hour boil notice for customers?

    The City of Tyler released this statement:

    “It is not normal for us to have a water sample test positive for E.coli.  We take dozens of samples everyday at various points around the City. Those samples got to the North East Texas Public Heath Regional Laboratory in Tyler to be tested according to TCEQ requirements.  

    The boil water notice had to be issued  as the result of a single routine sample site tested showing the presence of e. coli, followed by a repeat sample at the same site in Central Tyler showing the presence of total coliform. E. coli was only found in one sample site out of many tested.   

    Tyler water meets and exceeds all State and Federal standards. Our water system is safe.”

    Famed environmental activist, Erin Brockovich, has long expressed concerns over the safety of the city’s water. In 2015, responding to another TWU water contamination incident, she posted on Facebook that the City was downplaying the incident. City officials were quick to respond to her post, “Our drinking water is the No. 1 priority of this department,” Assistant City Manager Susan Guthrie said. “We followed exactly what TCEQ requires us to do.”

    No matter your opinion on the safety of Tyler’s water, the fact remains that the city was quick to respond in both situations. When disaster strikes, water facilities need to be prepared to react assuredly and quickly to ease customers’ minds. To avoid being caught unprepared, the EPA offers this guidance on how to react in situations like these. The City of Tyler followed the guidance of The Distribution System Contamination Response Procedure (DSCRP) outlined by the EPA, does your facility have a plan in place to do the same?

    Deregulation, Investment, Risk: The 2024 U.S. Presidential Shift in Water Policy and Implications for Water Treatment 

    By
    Melissa Diehl
    -

    The re-election of Donald Trump in 2024 brings with it a notable shift in U.S. water policy. As the new administration moves away from sustainability-focused initiatives, water treatment and utility professionals will see a change in infrastructure funding, water quality regulations, climate change policy, and the overall regulatory landscape. Let’s explore how these expected changes will affect various aspects of the water industry. 

    Infrastructure: Moving Toward Private Investment 

    Under the Biden administration, modernizing water infrastructure was a priority, with the Bipartisan Infrastructure Law directing $3.6 billion in 2024 alone toward water systems. This funding supported lead removal, pipeline modernization, and projects aimed at protecting public health. Trump’s administration is likely to reduce federal intervention in water infrastructure, opting instead to encourage state, local, and private investment partnerships. 

    For water treatment professionals, this shift means that reliance on federal grants and subsidies for upgrading systems may decrease. Instead, a new focus on private investment may require utilities to engage in public-private partnerships that prioritize economic efficiency. While this market-centered approach could encourage innovation and cost-cutting, it may also lead to fewer projects targeting the underserved, as private investors prioritize quick returns over broad public health initiatives. 

    Water Quality: A Deregulatory Agenda 

    Water quality protection was a central issue for the Biden administration, which implemented the first national drinking water standards for PFAS and worked to remove lead service lines in vulnerable communities. Conversely, Trump’s approach is likely to reduce federal regulations and oversight. A prime example of this approach is the 2020 Navigable Waters Protection Rule, which redefined federal protections for smaller streams and wetlands, effectively reducing the scope of the Clean Water Act. 

    While reduced federal oversight may temporarily lower compliance costs and ease the regulatory burden for utilities, this change could pose long-term challenges. Water utilities, especially those near deregulated industries, may face increased contamination risks if pollution control standards are relaxed. This means more local governments and utilities may need to take on additional responsibilities to ensure water quality, which could lead to increased costs or pressure to establish local regulations in areas previously protected by federal standards. 

    Climate Change: Shifting Responsibility for Resilience 

    Climate resilience was an urgent priority for the Biden administration, which allocated billions to prepare water systems for climate-related threats such as floods and droughts. In contrast, Trump’s stance downplays climate change concerns in favor of supporting fossil fuel development and reducing environmental regulation. 

    This pivot could leave many water utilities, especially those in vulnerable regions, with limited federal support for climate adaptation projects. Consequently, utilities will likely need to secure alternative funding to adapt infrastructure for extreme weather. Private funding for resilience projects may be challenging to secure, as immediate financial returns are not always evident. Water professionals may also experience uneven climate readiness across regions, with wealthier or urban areas better positioned to fund their adaptation needs than rural or underserved areas. 

    Navigating the New Landscape in Water Treatment 

    For water treatment professionals, managing operational risk in this new landscape will require adaptive strategies to handle potential contamination or infrastructure deficiencies. Some utilities may benefit from reduced regulatory costs, but others might face heightened exposure to liability if contamination incidents arise from relaxed standards. 

    With the water industry shifting from federal to private-sector-driven initiatives, companies that support the water sector will need to adapt. The transition away from federally mandated sustainability initiatives may decrease demand for certain engineering and construction projects, as public contracts for sustainability-focused infrastructure are expected to decline. Instead, the focus may shift to cost-effective, market-driven projects, especially those funded through public-private partnerships. 

    For digital solution providers, the decrease in compliance-based demands could impact tools focused solely on regulatory reporting. However, as utilities increasingly prioritize operational efficiency, demand for digital solutions that enhance cost reduction and equipment longevity is likely to persist. 

    In the water treatment sector, relaxed water quality standards may reduce the immediate need for advanced treatment technologies. Nonetheless, sectors with high quality standards—such as pharmaceuticals and food production—will still require these technologies, sustaining demand for advanced treatment options in certain applications. 

    A Proactive Path Forward 

    As the water industry faces regulatory shifts and evolving public expectations, remaining agile and adaptable will be essential. Companies can build resilience by emphasizing data-driven decision-making, adopting technologies that streamline operations, and actively engaging with private investors to secure funding for essential projects. While the short-term outlook may bring some regulatory relief, the industry’s commitment to responsible water management will play a significant role in ensuring the sustainability and quality of U.S. water resources in the long term. 

    In the face of anticipated challenges, the water sector has an opportunity to lead by example, demonstrating how innovation and resilience can sustain high standards in an evolving regulatory landscape. By prioritizing adaptability and public health, water utilities and supporting industries can navigate the changing policy environment while continuing to safeguard the nation’s water resources.

    Polluted Water with PFAs

    The U.S. Environmental Protection Agency (EPA) this week introduced new national drinking water standards, marking a significant regulatory step to limit exposure to perfluoroalkyl and polyfluoroalkyl substances (PFAS), commonly known as “forever chemicals.” These substances, which have been linked to various health risks including cancer and liver disease, are notoriously persistent in the environment and human body. Under the new regulations, six types of PFAS—PFOA, PFOS, PFNA, PFHxS, GenX chemicals, and additional combinations—are now subject to stringent limits due to their health risks. The EPA has set the maximum contaminant levels (MCLs) at 4 parts per trillion for PFOA and PFOS, and 10 parts per trillion for PFNA, PFHxS, and GenX chemicals.

    This regulatory action follows mounting evidence of PFAS’ adverse health impacts, such as increased risks of kidney and liver cancer, immune system damage, and developmental issues in children. The EPA’s decision aims to reduce these health risks by enforcing lower contamination levels and requiring public water systems to undertake significant testing and treatment if levels exceed these new standards.

    The implementation of these limits is expected to impact between 6% to 10% of the nation’s public water systems, translating to a need for upgrades and treatment technologies across approximately 4,100 to 6,700 systems. This undertaking underscores the EPA’s commitment to public health, with anticipated benefits including the prevention of thousands of deaths and serious illnesses.

    To support the compliance with these new standards, the EPA has allocated significant funding, notably $1 billion from the 2021 federal infrastructure law. This funding aims to assist states, territories, and public water systems in implementing PFAS testing and treatment solutions. Additional financial support has stemmed from litigation against PFAS manufacturers, including a notable settlement where companies like 3M have agreed to pay billions to affected water providers.

    While these new regulations represent a critical step towards safeguarding drinking water, they also highlight ongoing challenges. The treatment and monitoring of PFAS are costly and complex, and the financial burden may ultimately be passed onto consumers, especially in smaller communities with fewer resources. 

    These actions are part of a broader effort by the EPA to tackle environmental contaminants and ensure cleaner, safer water for all Americans. As the agency continues to expand its oversight and regulation of PFAS, further measures and funding will likely be necessary to address the pervasive challenges posed by these chemicals in the environment.
