WDEQ Launches Free PFAS Testing for Public Water Systems, Helping Systems Comply with New EPA PFAS Drinking Water Regulation
Public water systems must sign up by December 5, 2025, for no-cost monitoring of per- and polyfluoroalkyl substances (PFAS).
CHEYENNE, WYOMING - The Wyoming Department of Environmental Quality (WDEQ) today announced it is offering free per- and polyfluoroalkyl substances (PFAS) testing to all public water systems, with a sign-up deadline of December 5, 2025. The testing is being offered through WDEQ’s PFAS in Drinking Water Monitoring Assistance Program, funded by Wyoming’s Emerging Contaminants in Drinking Water Grant.
PFAS, sometimes referred to as “forever chemicals,” are a large class of human-made chemicals known for their widespread use in industry, consumer products, and certain firefighting foams and potential to accumulate, persist, and impact people and the environment. Due to the potential for PFAS to impact human health, in April 2024, the U.S. Environmental Protection Agency finalized the PFAS National Primary Drinking Water Regulation. The regulation requires community public water systems and non-transient non-community public water systems (e.g., hospitals, schools, churches, mining and industrial facilities that are not a community water system) to monitor and meet regulatory limits for certain PFAS.
"We know that the new federal PFAS drinking water regulations pose a significant financial and logistical challenge for our state's water systems, especially those serving smaller communities," said Jennifer Zygmunt, Water Quality Division Administrator. “This assistance program aims to help alleviate some of those challenges by offering help with sampling, analysis, reporting, and operator training, all at no cost to the system or its customers. This is part of our broader efforts to understand and address PFAS contamination in Wyoming to protect human health and the environment.”
WDEQ is also encouraging public water systems that are not subject to the new PFAS drinking water regulation to participate in the program, as the data can help determine whether PFAS and other potential emerging contaminants may pose a risk to people or animals that use or consume water from these systems. Participation can also help determine whether public water systems may be eligible for PFAS and other emerging contaminant funding available through Wyoming’s Emerging Contaminant in Drinking Water Grant and/or State Revolving Loan Fund.
For participating systems, WDEQ's contractor can conduct site visits, collect samples, have the samples analyzed by a certified laboratory, provide results, recommend next steps, and provide hands-on and/or online PFAS sample collection training for operators, all at no cost to the system. For public water systems that are subject to the PFAS National Primary Drinking Water Regulation, monitoring can be scheduled to fulfill all initial monitoring requirements by the April 2027, deadline.
