HOW MUCH COULD MY TOWN OR CITY RECEIVE IN SETTLEMENT?

A Court Appointed Settlement Administrator will consider many factors to allocate funds, including:

Concentration of PFAS

Adjusted flow rates with averaging for three highest rates in a 10-year period

The goal is to calculate a ‘Capital Costs Component’ and an ‘Operations and Maintenance Costs Component’ for each settlement award. From there, your award may also qualify for a 4x multiplier if your PFAS test result reaches a certain level. Individual awards could be substantial, totaling millions of dollars for highly contaminated water systems.

DO I REALLY NEED AN ATTORNEY FOR PFAS RECOVERY?

The PFAS settlement process is not as straightforward as it might seem. While billions in funding have been allocated, the path to recovering those funds involves dense legal agreements, multiple deadlines, and evolving eligibility criteria.


Here’s why working with legal counsel is essential:

COMPLEX SETTLEMENTS AGREEMENTS

01.

The 3M Master Settlement Agreement is 62 pages long and includes 18 exhibits. Interpreting these documents incorrectly—or missing key provisions—can cost your system millions in missed funding.

MULTIPLE CLAIMS AND DEADLINES

Testing Claims, Action Funds, Special Needs Funds, and Supplemental Funds all have different forms and deadlines extending to 2030. A legal team ensures no opportunity is missed.

02.

03.

ONGOING INTERPRETATIVE GUIDANCE

Many rules are still being clarified. Working with attorneys who are tracking how claims administrators interpret the agreements helps maximize your eligible reimbursement.

04.

UNRESOLVED CLAIMS STILL IN PLAY

Claims involving wastewater systems, personal injury, private wells, and additional defendants (such as Tyco and BASF) are still active. Legal guidance ensures you’re positioned for future recovery.

05.

MISTAKES ARE EXPENSIVE

Filing incorrectly, or failing to document qualified expenses properly, can result in denial of funds. Experienced counsel adds value by helping you navigate the process correctly from the start.

THE IMPACT OF PFAS ON YOUR COMMUNITY

Addressing PFAS contamination isn't just about ensuring clean water; it's a significant financial challenge. Remediation efforts, long-term health care for affected individuals, and potential declines in property values can strain a community's budget.

PFAS cause cancer and other health effects like: 

High Blood Pressure

High Cholesterol

Decrease in Vaccine Response in children

Kidney Cancer

Preeclampsia

Ulcerative Collitus

Testicular Cancer

AGENCY FOR TOXIC SUBSTANCES AND DISEASE REGISTRY logo

The Environmental Protection Agency (EPA) has significantly tightened drinking water standards for PFAS chemicals. Under new federal regulations, the limit for PFOA and PFOS in public drinking water is now 4 parts per trillion (ppt)—a major reduction from the previous 70 ppt advisory. These updated limits are part of the EPA’s nationwide effort to strengthen protections for public drinking water.

A water system that properly protects against harmful PFAS can cost municipalities tens of millions of dollars. Failing to file a claim and lawsuit in the MDL could put the bill on your taxpayers.


Stag Liuzza is working with municipalities across the country to hold the chemical companies that polluted the water accountable for PFAS remediation costs.

CRITICAL QUESTIONS FOR CLEAN DRINKING WATER

Federal guidelines on PFAS contamination are expected to tighten in 2023 and will, for many towns and cities, require expensive PFAS remediation.

FREQUENTLY ASKED QUESTIONS

ARE ALL PFAS CLAIMS SETTLED?

No. While major settlements with 3M and DuPont have been announced, claims involving other defendants—like Tyco and BASF—as well as personal injury, wastewater systems, and private wells remain active. Our team is monitoring these developments closely and can help you navigate unsettled claims and upcoming opportunities for compensation.

Yes. PFAS settlements—particularly the 3M and DuPont agreements—are lengthy, complex, and contain multiple claim types and deadlines. The 3M settlement alone is 62 pages long and includes 18 exhibits.

An attorney ensures you file correctly, on time, and with full documentation, helping you avoid costly errors. Legal representation also positions you to pursue compensation from unsettled claims, such as those related to wastewater systems or additional defendants like Tyco and BASF.

Mistakes or omissions can result in lost funding. Working with an experienced legal team increases your chances of a successful recovery—and protects your interests in future litigation.

DO I NEED A LAWYER TO FILE A PFAS CLAIM?

IS THERE CONCERN OF THE NEW ADMINISTRATION REDUCING OR ELIMINATING EPA STANDARDS?

No. The new administration has stated the standards will not change. Even if they did, the 3M and DuPont settlements must be paid as ordered by the Court.

WHAT HAPPENS TO FUNDS FOR COMPLIANCE IF COMPLIANCE STANDARDS CHANGE?

Nothing. The Settlement Agreement requires payment as ordered by the Court.

WILL THE NEW ADMINISTRATION ROLL BACK OR DELAY SAFE DRINKING WATER ACT REGULATIONS?

The new administration is providing more time for Public Water Systems (PWS) to comply with the PFAS standards. This does not impact the terms of the settlement agreements of 3M and DuPont.

ARE THERE PAYMENTS AVAILABLE FOR A WELL THE CITY TOOK OFFLINE AND CANNOT USE BECAUSE OF PFAS?

Yes. All water sources are considered, including backup sources that are not currently in use or seldom used.

ARE THERE GEOGRAPHICAL LIMITS TO PUBLIC WATER SUPPLY PFAS CLAIMS FOR SETTLEMENT FUNDS?

No. The entire United States of America, its territories, and tribal nations are included in the settlement.

If your PWS opted out of the settlements, you should consider whether or not to file a lawsuit to protect your rights.

WHAT ADVICE DO YOU HAVE FOR MUNICIPALITIES THAT OPTED OUT OF THE CLASS ACTION?

WHAT IS IT ABOUT AIRPORTS THAT GENERATE PFAS COMPOUNDS?

Defendants have not settled with airports. Airports continue to file civil action claims in the MDL.

WHO OWNS THE CLAIM: THE MUNICIPALITY PRODUCING THE WATER OR THE MUNICIPALITY PURCHASING THE WATER?

Generally, the PWS selling water controls the source and retains the obligation to filter the water. Therefore, the seller is typically paid the settlement money related to the source. However, exceptions exist, especially when the seller fails to make a claim in the 3M and DuPont Settlements.

WHERE CAN I FIND THE LIST OF WATER SYSTEMS ELIGIBLE FOR CLAIMS?

The eligible PWS list for Phase Two of the 3M and DuPont settlements is available on CleanGroundwater. The exhibits to the Master Settlement Agreement list all qualifying PWS in the settlement.

IF MY STATE SUED 3M FOR PFAS, IS THERE STILL AN OPPORTUNITY FOR THE MUNICIPALITY TO FILE A SETTLEMENT CLAIM?

Yes. The state settlements do not impact the obligation of 3M and DuPont to pay as agreed in the settlement contracts.
