OKLAHOMA
PUBLIC WATER SYSTEMS PHASE 2 PFAS SETTLEMENT
Oklahoma’s water systems are at a critical decision point.
HOW MUCH COULD YOUR PWS RECEIVE?
The settlement administrator will evaluate factors such as:
- PFAS concentration levels in your water sources.
- Adjusted flow rates (based on your three highest years in a 10-year period).
Oklahoma cities with high PFAS scores could qualify for a 4x multiplier on their PFAS settlement awards, potentially unlocking millions of dollars for their PWS.
A list of Oklahoma PWS’s that qualify for the 3M and DuPont settlements is provided at the end of this page.
Estimated Flow Rates:
We estimate flow rates are approximately 1,500 GPM per 10,000 people served.
This is an estimate and there may be variation due to many factors including commercial use of the water system.
The actual flow rate is known by the water utility.

Stag Liuzza has decades of experience handling environmental litigation nationwide. The judge overseeing the national AFFF PFAS litigation appointed Mike Stag to the PEC. Our PFAS lawyers have secured billions in settlements from 3M and DuPont. Whether you represent a small rural water district or a large metropolitan area, we can help you navigate PFAS lawsuits, federal court proceedings, and all aspects of filing a successful PFAS settlement claim. Stag Liuzza’s track record includes:
- A major water district serving over 200,000 customers, estimated to receive $14 million+ in settlement funds
- A mid-size municipality serving 15,000 customers, estimated to recover $3.3 million
- A smaller town serving 5,000 customers, expected to obtain $4.7 million in funding
Oklahoma municipalities have the opportunity to access vital funding through Phase 2 of the national PFAS settlement with 3M and DuPont. This funding is essential for PWS to reimburse PFAS-related costs, conduct water testing, implement remediation plans, and establish long-term protection against PFAS contamination.
Missing key deadlines will forfeit settlement funds owed to Oklahoma public drinking water systems, and put significant financial strain on both systems and rate payers.
PUBLIC WATER SYSTEMS: PFAS SETTLEMENT - KEY INFORMATION
Oklahoma’s public drinking water systems are at a critical juncture in the fight against PFAS contamination. These PFAS chemicals—often called “forever chemicals”—pose serious health concerns for residents, threaten local ecosystems, and can result in tens of millions of dollars in remediation costs if left unaddressed. Many products, including firefighting foam, electronics, and packaging, contain PFAS. This contributes to environmental contamination and serious health risks.
The Phase 2 PFAS Settlement available to many Oklahoma cities and towns provides financial resources to help municipalities test for, mitigate, and manage PFAS exposure in their water supply in order to follow compliance with evolving federal guidelines and safeguarding public health.
The Phase 2 Public Water System Settlement provides essential funding for Oklahoma public water systems to tackle PFAS contamination. This settlement supports PFAS remediation and ensures compliance with federal PFAS standards.
These resources enable municipalities to identify and remediate contamination effectively, helping protect their water systems. Acting promptly reduces the financial burden of treatment measures and ensures compliance with federal PFAS standards.

UNDERSTANDING PFAS CONTAMINATION
PFAS, or per- and poly-fluoroalkyl substances, are a group of synthetic chemicals that have been widely used in various industries and consumer products. These chemicals are known for their resistance to heat, water, and oil, making them useful in applications such as non-stick cookware, food packaging, and firefighting foam. However, PFAS have also been linked to serious health concerns, including cancer, thyroid disease, and reproductive issues.
PFAS are often referred to as “forever chemicals” because they do not break down naturally in the environment and can persist for hundreds of years. This persistence has led to widespread contamination of soil, water, and air, making PFAS a widespread environmental and public health concern.
HEALTH EFFECTS OF
PFAS EXPOSURE
Exposure to PFAS has been linked to a range of serious health effects, including:
CANCER:
PFAS have been linked to an increased risk of certain types of cancer, including testicular and kidney cancer.
THYROID CONDITIONS:
PFAS have been shown to disrupt thyroid function, leading to conditions such as hypothyroidism.
REPRODUCTIVE ISSUES:
PFAS have been linked to reproductive problems, including reduced fertility and increased risk of pregnancy complications.
IMMUNE SYSTEM SUPPRESSION:
PFAS have been shown to weaken the immune system, making people more susceptible to illness and infection.
The health effects of PFAS exposure can be severe and long-lasting, making it essential to take steps to minimize exposure and address contamination.
PFAS CONTAMINATION & REMEDIATION IN OKLAHOMA
PFAS chemicals are widely used across various industries, including firefighting foam (aqueous film-forming foam), food packaging, and other everyday products. Over time, these harmful chemicals have seeped into drinking water supplies, contaminated groundwater, and even private drinking water wells throughout Oklahoma.
The Environmental Protection Agency (EPA) and other government agencies have issued guidelines under legislation such as the Toxic Substances Control Act and the Resource Conservation and Recovery Act to address PFAS pollution. Oklahoma municipalities must take swift action to meet these federal guidelines, mitigate legal exposure, and protect public health.
Public drinking water systems in Oklahoma can expect to receive millions of dollars in settlement funds needed to respond to PFAS in its water sources. The 3M and DuPont Phase 2 settlement offers financial support necessary to avoid passing the bill to taxpayers and rate payers.
ESTIMATED SETTLEMENT AWARDS:
MULTIPLIER EFFECT:
Municipalities with any detectable PFAS and significant flow rates could qualify for awards in millions.
Without action, Oklahoma PWS’s with detectable levels of PFAS may face long-term consequences, including increased public health risks, regulatory action, reduced property values, and significant financial burdens.
DON'T RISK LOSING FUNDING FOR
OKLAHOMA'S PUBLIC WATER SYSTEMS
Municipalities across Oklahoma face potential remediation expenses in the tens of millions. Litigation to recover costs from the PFAS industry is ongoing at the federal level. The AFFF Product Liability Litigation is the national case that resulted in the $13.6 Billion settlement with 3M and Dupont.
Public water systems in Oklahoma risk losing out on millions of dollars if they fail to take legal action. Specifically, water systems must meet not only the settlement deadlines, but also evaluate any unsettled damage claims. These claims include costs to public waste water and sewage treatment systems. Many defendants in the litigation have not settled with public drinking water systems in the hope that they will fail to take action. Public water systems that fail to act before the deadlines will forfeit their claim to millions of dollars in funding.
Therefore, public water systems must take immediate action to protect their financial interests.

STEPS FOR FILING A PFAS CLAIM
For Oklahoma municipalities and public water systems, filing a settlement claim and joining the ongoing litigation is a critical step in securing the financial and legal protections your community needs. Below is a brief overview for municipal water systems looking to recover costs related to PFAS:
01
Test Each Water Source for PFAS
- Arrange for reputable laboratory testing to determine PFAS concentration levels in your public water sources. The settlement terms require testing of each PWS water source.
- The settlement pays the PWS if there are any positive detections, even below the EPA’s 4 ppt standard.
Stag Liuzza may be able to help cover the costs of testing.
02
Retain Experienced PFAS Counsel
- Partner with an environmental law firm specializing in PFAS litigation to navigate complex legal settlement terms.
- Hiring an attorney can help you meet strict court deadlines, gather essential documentation, and maximize potential settlement money.
03
File Your PFAS Settlement Claim
- Submit all required documentation, including PFAS testing results and flow rate data, to initiate your claim.
- Stay compliant with court deadlines and settlement requirements to avoid disqualification and secure settlement funds.
FREQUENTLY ASKED QUESTIONS
It is a nationwide agreement that provides funding and cost recovery to public water systems. Oklahoma PWS’s can file settlement claims to receive financial support to pay for or reimburse costs related to testing, remediation, and regulatory compliance.
Specific PFAS chemicals of major concern include PFOA and PFOS, although new PFAS compounds continue to emerge. The national settlement with 3M and DuPont pays systems for any detections related to many different PFAS chemicals.
Exposure to PFAS in drinking water has been linked to kidney cancer, thyroid issues, immune system disruptions, and other significant health problems
Water systems qualifying for the Phase 2 settlement are listed in an exhibit to the Master Settlement Agreement for 3M and DuPont. The amount of money each water system will receive depends on factors like PFAS concentrations and flow rates. Completing PFAS testing in each water source is crucial to recovering money.
Reimbursement for settlement testing costs is expected the first quarter of 2026. Action fund payments are expected to start the fourth quarter of 2026.
