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.

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.

The post PFAS Regulation at Crossroads With EPA Litigation appeared first on Water Treatment 411.

The catalyst for this transformation was an energy audit conducted by Jacobs in 2022 at the Moccasin Bend Water Treatment Facility. This audit revealed a number of inefficiencies and outdated technologies that were contributing to high operating costs and environmental concerns. 

MABR vs. HPO: A Technological Advance 

One of the most significant issues identified was the facility’s reliance on a high-purity oxygen (HPO) process for sludge treatment. This outdated method was both energy-intensive and inefficient. Jacobs recommended replacing it with a membrane aerated biofilm reactor (MABR), a more advanced technology that offers superior performance and lower energy consumption. 

Unlike HPO, which requires the continuous introduction of oxygen gas into the wastewater, MABR utilizes a membrane to facilitate the transfer of oxygen from the air to the wastewater. This passive oxygen transfer process is more efficient and energy-saving than the active aeration employed in HPO. Additionally, the biofilm that forms on the membrane surface in MABR provides a highly effective environment for microbial activity, leading to improved sludge degradation and nutrient removal. This enhanced biological performance, coupled with the reduced energy consumption, makes MABR a more sustainable and cost-effective option for sludge treatment compared to HPO. 

Optimizing Efficiency  

In addition to the MABR, Jacobs suggested several other improvements, including converting the solids train from lime stabilization to thermal hydrolysis (THP) and mesophilic anaerobic digestion (MAD), and incorporating fine bubble aeration to further reduce energy costs. 

The proposed improvements to the solids train and aeration system would also contribute to increased energy efficiency. THP involves subjecting the sludge to high temperatures and pressures, which breaks down organic matter and improves its biodegradability. This pre-treatment step enhances the efficiency of subsequent anaerobic digestion, leading to increased biogas production. The biogas can then be used to generate electricity or heat, reducing the facility’s reliance on external energy sources.  

Fine bubble aeration, which involves the introduction of small air bubbles into the wastewater, promotes more efficient oxygen transfer and reduces the amount of energy required for aeration. By optimizing the solids treatment process and implementing energy-efficient aeration techniques, the facility could achieve significant reductions in overall energy consumption. 

How the Project Will Pay for Itself 

The proposed changes came with a significant price tag of $136 million. However, Jacobs’ analysis demonstrated that the long-term benefits would far outweigh the initial investment. The optimized operation at Moccasin Bend was estimated to generate savings in several areas, including biosolids reduction, increased biogas production, reduced hypochlorite demand, energy savings, and reduced cake hauling costs. Moreover, the facility was expected to generate additional revenue through the sale of biogas. Jacobs estimated that the savings and revenue from the changes would cover the costs of the investment in approximately 15 years.

The Persistence of PFAS in Waste Incineration 

A new study by Sofie Björklund, a doctoral student at Umeå University, has revealed that PFAS can survive the high temperatures of waste incineration and continue to spread into the environment. Despite the incineration process, these “forever chemicals” can be found in the ash, condensate, and flue gases emitted by waste-to-energy plants. 

The study identified short-chain PFAS as the most common type of PFAS found in the byproducts of waste incineration. This is particularly concerning because short-chain PFAS are highly mobile in water and difficult to capture once they enter the environment. Understanding the breakdown products of longer-chain PFAS is essential for developing effective mitigation strategies. 

Sources Contributing to PFAS Contamination 

The addition of sewage sludge to waste fuel can significantly increase PFAS emissions from incineration plants. This finding highlights the importance of careful consideration of waste composition and treatment processes. 

Waste-to-energy plants are not the only source of PFAS emissions. Firefighting training sites, wastewater treatment plants, and other industrial facilities also contribute to the contamination of our environment. Addressing the issue of PFAS requires a comprehensive approach that targets all significant sources. 

What Can Be Done? 

While flue gas cleaning can reduce PFAS emissions, the effectiveness varies depending on the specific PFAS compounds. The study found that wet flue gas treatment removed an average of 35% of total PFAS. However, more advanced cleaning technologies may be necessary to achieve significant reductions. 

To minimize PFAS emissions from waste management, it is essential to have better end-of-life planning for products containing these chemicals. This includes developing strategies for recycling, reuse, or safe disposal. 

Future Research Direction 

The research team plans to expand their studies to investigate the conditions under which PFAS breakdown might occur and to identify the resulting breakdown products.
