PFAS Grants for Municipalities

PFAS Grants for Municipalities: Navigating Funding Opportunities for Water Safety

Introduction

As municipalities grapple with the pervasive contamination of per- and polyfluoroalkyl substances (PFAS) in water supplies, the urgency to address this public health crisis is more pressing than ever. With an estimated 6,000 varieties of PFAS identified, their widespread use in industrial applications, firefighting foam, and consumer products has left a lasting mark on groundwater and surface water systems. In July 2025, understanding the financial resources available through dedicated PFAS grants for municipalities is crucial to effectively implementing remediation technologies and ensuring safe drinking water for communities.

This article surveys the programs covered in our guide to PFAS funding and grants. The largest federal source is examined in detail in our article on the Bipartisan Infrastructure Law and PFAS.

Understanding PFAS and Their Impact on Water Supplies

PFAS, often dubbed "forever chemicals," resist degradation and accumulate in the environment and human body, leading to various health risks, such as kidney cancer, liver damage, and developmental issues in children. The Environmental Protection Agency (EPA) has set a lifetime health advisory level of 0.004 parts per trillion for PFOS and PFOA, the two most studied compounds, unveiling the necessity for municipalities to adopt immediate action plans.

That figure has been superseded. The 0.004 part-per-trillion value was an interim health advisory for PFOA issued in 2022; the corresponding PFOS advisory was 0.02 ppt. Both were non-enforceable and set below what laboratories could measure. They were overtaken in 2024 by enforceable maximum contaminant levels, summarized below.

Regulatory status, current as of this revision: EPA finalized the PFAS National Primary Drinking Water Regulation on April 10, 2024, setting enforceable maximum contaminant levels of 4.0 parts per trillion each for PFOA and PFOS, 10 parts per trillion each for PFHxS, PFNA and HFPO-DA (GenX), and a Hazard Index for mixtures of PFHxS, PFNA, HFPO-DA and PFBS. Public water systems must complete initial monitoring by 2027. In May 2026 EPA published two proposed rules: one would retain the PFOA and PFOS limits while allowing systems to request an extension of the compliance date from 2029 to 2031, and the other would rescind the limits for PFHxS, PFNA, HFPO-DA and the Hazard Index. Both remain proposals and related litigation is ongoing, so the status of those four is unsettled. Many states maintain their own enforceable PFAS standards, unaffected by the federal proposals. Because this area is under active rulemaking, re-check EPA and state sources before relying on any figure here.

User Intent Analysis

The target audience includes municipal leaders, engineers, and water treatment facility operators primarily looking for funding solutions to manage PFAS contamination. The primary user intent can be classified as Problem/Solution and Informational; they seek funds and knowledge to implement effective water treatment solutions.

Current Regulatory Landscape

Recent Legislative Developments

With new regulations continually emerging, municipalities need to remain vigilant. In 2024, the EPA proposed the PFAS Action Plan 2.0 aimed at holding manufacturers accountable and expediting research on PFAS treatment technologies. Furthermore, federal legislation such as the Bipartisan Infrastructure Law (BIL) includes specific allocations for PFAS remediation.

Verification note: EPA has published a PFAS Action Plan (2019) and a PFAS Strategic Roadmap (2021), but no “PFAS Action Plan 2.0” proposed in 2024 could be identified. This reference should be corrected or removed.

The Role of State and Local Regulations

Local regulations, often stricter than federal standards, place additional pressure on municipalities. Many states have set their paramount PFAS limits, which can complicate compliance measures and elevate costs.

Funding Opportunities for PFAS Remediation

Federal Grants and Programs

EPA’s Grant Programs: The EPA administers various grant programs designed to assist municipalities in PFAS monitoring and remediation. Key programs include:

  1. Drinking Water State Revolving Fund (DWSRF): Provides low-interest loans that can be converted to grants based on job creation and public health benefits.

    That description of how DWSRF grants work is not accurate. States award principal forgiveness, which functions as a grant, according to affordability and disadvantaged-community criteria set in each state’s program, not on job creation. For PFAS specifically, the emerging-contaminants portion of DWSRF funding must be provided entirely as principal forgiveness or grants, as explained below.

  2. Community Development Block Grant (CDBG) Program: Offers funding for projects aimed at improving public infrastructure, which can include water treatment solutions.

  3. Clean Water State Revolving Fund (CWSRF): Focused on wastewater treatment but can also fund projects that address PFAS contamination in treated effluent.

How BIL emerging-contaminants funding is actually structured: the law created three dedicated emerging-contaminants streams, each appropriated in five annual tranches across federal fiscal years 2022 through 2026:

  • DWSRF Emerging Contaminants — $4 billion. Capitalization grants to state Drinking Water State Revolving Funds, with PFAS the stated priority. The law requires 100 percent of these funds, less set-asides, to go out as additional subsidy, meaning principal forgiveness or grants rather than repayable loans.
  • Emerging Contaminants in Small or Disadvantaged Communities (EC-SDC) — $5 billion. A grant program administered by EPA through the states for small or disadvantaged public water systems, covering infrastructure, source water work, and testing.
  • CWSRF Emerging Contaminants — $1 billion. Through state Clean Water State Revolving Funds, for wastewater and stormwater projects addressing emerging contaminants.

Two practical points follow. First, almost none of this money is applied for directly from Washington: it reaches utilities through state programs, and projects must generally appear on the state’s Intended Use Plan project priority list. Second, FY2026 is the final year of BIL appropriations. That does not mean the money disappears on the last day of the fiscal year: states continue to award and disburse these funds through their own fiscal-year cycles, and unused emerging-contaminants allotments are reallocated to other states after two years. But no new BIL tranches follow, so utilities should treat the remaining funds as finite and check their state program’s current Intended Use Plan. Projects receiving SRF funds must also comply with Build America, Buy America domestic-content requirements for iron, steel, manufactured products, and construction materials.

This list also omits what may be the largest single PFAS funding source for many water systems: the class action settlements with PFAS manufacturers. Settlements reached in 2023 by 3M and by DuPont, Chemours, and Corteva with public water systems, approved by the court in 2024, together exceed $11 billion, with 3M’s payments spread over more than a decade. Eligibility and payment amounts depend on a system’s size and its PFAS test results, and payments are not restricted to the uses that federal grants impose. Systems that detected PFAS should confirm whether they filed claims and where they stand in the payment schedule, since settlement funds can be used alongside SRF assistance.

State-Specific and Local Grants

Many states have developed dedicated PFAS grants, such as California’s Proposition 68 and Michigan’s PFAS Action Response Team (PART) grant programs, which provide municipalities with vital resources for sampling and remediation. Engaging with local health departments can uncover additional funding streams tailor-made for community needs.

Both examples need correcting. California’s Proposition 68 was a 2018 bond measure covering parks, water, and climate resilience rather than a dedicated PFAS grant program, and Michigan’s MPART, the Michigan PFAS Action Response Team, is a multi-agency coordinating body that investigates contamination rather than a grant program. Several states do run dedicated PFAS funding, often through their SRF emerging-contaminants programs or state bond funds, so the practical step is to contact the state SRF administrator directly.

Applying for PFAS Grants

Steps to a Successful Grant Application

  1. Research and Identify Grant Opportunities: Use databases like Grants.gov and state-specific platforms to pinpoint applicable grants.

    For PFAS treatment projects, Grants.gov will rarely be the right starting point, because the major programs are administered by states rather than awarded directly by federal agencies. The effective route is to get the project onto the state SRF’s project priority list, typically by submitting a project questionnaire or pre-application during the state’s annual solicitation, which feeds its Intended Use Plan. Having PFAS sampling results and a preliminary engineering report ready is often what separates funded projects from waiting-list ones.

  2. Develop a Comprehensive Proposal: Highlight the necessity for funding due to community health risks. Include data and statistics reflecting the PFAS levels in local water sources.

  3. Engage Stakeholders: Involve local community members, health officials, and environmental groups to lend credibility and support to your application.

  4. Budgeting and Cost Assessment: Clearly outline expected costs associated with remediation, monitoring, and maintenance of water treatment systems. Utilize cost-benefit analyses to demonstrate the economic impact of PFAS remediation.

  5. Monitoring and Reporting: Be prepared to outline a long-term strategy for monitoring PFAS levels after remediation activities. Demonstrating the ability to track improvements will bolster future funding opportunities.

Effective Water Treatment Solutions for PFAS

Advanced Treatment Technologies

Municipalities can explore several innovative technologies for PFAS treatment:

  • Granular Activated Carbon (GAC) Filtration: Highly effective for removing certain PFAS compounds, although periodic replacement is necessary, and costs can add up.

  • Ion Exchange Resins: Particularly effective for shorter-chain PFAS, though installation costs and operational management need consideration.

  • Reverse Osmosis: Though effective in removing most PFAS, its cost and waste production must be managed.

Case Study Showcases

Municipalities that have successfully implemented PFAS remediation projects can serve as strong examples. For instance, the city of Harrisburg, Pennsylvania, secured a $1 million EPA grant to adopt an integrated water treatment solution emphasizing GAC filtration. The project clearly documented health improvements and increased community trust in local water systems.

Verification note: this case study could not be matched to a documented project or grant award, and the claim of documented health improvements is not something a treatment project of this kind would typically be able to demonstrate. It should be verified or removed.

Challenges Facing Municipalities

Funding Gaps and Budget Constraints

Despite available funding, many municipalities face escalating costs related to implementation and maintenance. The construction of new treatment facilities, coupled with regulatory compliance costs, often overwhelms limited municipal budgets.

Public Engagement and Communication

Ensuring community buy-in is essential. Municipalities must maintain transparency and actively communicate risks and ongoing efforts to remediate PFAS contamination.

Conclusion

As pressure mounts on municipalities to address PFAS contamination in their water supplies, understanding and leveraging available PFAS grants becomes increasingly critical. Navigating the regulatory landscape and applying for federal and state grants may provide invaluable financial support for effective water treatment solutions. By staying informed on funding opportunities and technological advancements, municipalities can not only secure the financial resources needed for PFAS remediation but also ensure a healthier future for their communities. The stakes are high, but the right funding strategy can yield transformative outcomes in public health and environmental stewardship.

For ongoing updates on PFAS regulation and funding opportunities, municipalities should engage with industry webinars and subscribe to relevant newsletters. Optimizing the approach to PFAS grants for municipalities will fortify community water safety, ultimately paving the way for healthier, sustainable municipal infrastructures.
