Wisconsin municipalities have the opportunity to access vital funding through Phase 2 of the national PFAS settlement. This funding is essential for cities and towns to conduct water testing, implement remediation plans, and establish long-term protection against PFAS contamination.


Missing key deadlines could put Wisconsin communities at risk, exposing them to potential health hazards and significant financial strain on taxpayers.

Public water systems: PFAS contamination key information

PUBLIC WATER SYSTEMS: PFAS CONTAMINATION KEY INFORMATION

Wisconsin’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 and packaging have contained PFAS, contributing to environmental contamination and serious health risks.


The Phase 2 PFAS Settlement available to many Wisconsin 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 Wisconsin 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

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 WISCONSIN

Arizona municipalities have the opportunity to access vital funding through Phase 2 of the national PFAS settlement.

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 systems, contaminated groundwater, and even private drinking water wells throughout Wisconsin. Exposure to PFAS compounds has been linked to adverse health effects, including kidney cancer and other serious health problems.


The Environmental Protection Agency (EPA) and other federal 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. Wisconsin municipalities must take swift action to meet these federal guidelines, mitigate legal proceedings, and protect public health.


The cost of PFAS contamination and remediation for water systems across Wisconsin could reach tens of millions of dollars, depending on contamination levels. The Phase 2 settlement offers the financial support needed to implement costly water treatment systems and avoid passing the bill to taxpayers.

Public water systems in Arizona must act now to secure financial support for PFAS water treatment and infrastructure upgrades
ESTIMATED SETTLEMENT AWARDS:

Municipalities with high PFAS concentrations and large flow rates could qualify for awards in millions.

MULTIPLIER EFFECT:

Water systems with higher contamination levels may qualify for a 4x multiplier on settlement amounts.


Without action, Wisconsin cities and towns contaminated with PFAS may face long-term consequences, including increased public health risks, reduced property values, and significant financial burdens.

WHAT'S AT STAKE IN WISCONSIN'S PUBLIC WATER SYSTEMS?

Municipalities across Wisconsin face potential remediation expenses in the tens of millions. PFAS industry manufacturers, along with other chemical manufacturers, are involved in PFAS lawsuits and class actions at both the district court and federal court levels. Without strategic remediation plans, local fire departments, metropolitan water agencies, and community drinking water systems risk bearing the burden of toxic chemicals, forever chemicals, and hazardous constituents. Contaminated drinking water can lead to serious health risks and significantly impact economic stability in local communities. By participating in the PFAS settlement Wisconsin initiative, water systems can prevent further exposure to PFAS and avoid passing on massive costs to residents.

HOW MUCH COULD YOUR CITY RECEIVE?

The settlement administrator will evaluate factors such as:

  • PFAS concentration levels in your water system.
  • Adjusted flow rates (based on your three highest years in a 10-year period).

Wisconsin cities with high contamination levels could qualify for a 4x multiplier on their PFAS settlement awards, potentially unlocking millions in funding.

BENEFITS OF FILING FOR THE PHASE 2 SETTLEMENT?

The Phase 2 Settlement offers vital financial and legal benefits to Wisconsin’s municipalities. Below is an introduction to the core advantages:

01.

REDUCED FINANCIAL BURDEN:

Settlement awards alleviate expensive out-of-pocket expenses for municipalities, saving taxpayers from substantial rate hikes.

02.

PROTECT PUBLIC HEALTH:

Early identification and treatment of drinking water contaminated with toxic PFAS limit adverse health effects and potential personal injury claims.

03.

COMPLIANCE:

Align with federal lawsuit requirements and guidelines, including those set by the Comprehensive Environmental Response statutes, to avoid penalties.

04.

LONG-TERM COMMUNITY SAFEGUARD:

Address PFAS contamination proactively and protect future generations from dangerous PFAS compounds.

STEPS FOR FILING A PFAS LAWSUIT

PFAS lawsuits are being pursued nationwide to hold chemical manufacturers and other entities accountable for contaminating local water sources. For Wisconsin municipalities, filing a claim or joining the ongoing litigation is a critical step in securing the financial and legal protections your community needs. Below is a brief overview tailored to municipalities looking to address PFAS contamination:

Test Your Municipality’s Water for PFAS

01

  • Arrange for reputable laboratory testing to determine PFAS concentration levels in your public water systems.
  • These results will confirm if your water supply is contaminated and quantify the extent of the problem.

Stag Liuzza may be able to help cover the costs of testing, as well as keep testing results confidential until your municipality develops a plan for action.

02

Retain Experienced PFAS Counsel

  • Partner with an environmental law firm specializing in PFAS litigation to navigate complex legal proceedings.
  • Hiring an attorney can help you meet strict court deadlines, gather essential documentation, and maximize potential settlement or judgment awards.

03

File Your PFAS Lawsuit

  • 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.

Baseline PFAS testing is required for Arizona water systems seeking funding for contamination mitigation and treatment.
