PFAS in Drinking Water Monitoring Assistance Program
The PFAS in Drinking Water Monitoring Assistance Program aims to support public water systems and private well owners test drinking water sources for per- and polyfluoroalkyl substances (PFAS).
The program will collect and test drinking water samples from:
-
- Community water systems and non-transient non-community water systems required to meet initial monitoring requirements under the PFAS National Primary Drinking Water Regulation
- Public water systems not regulated under the PFAS National Primary Drinking Water Regulation
- Private wells in proximity to known or suspected sources of PFAS
WDEQ is in the process of hiring a contractor to oversee this program. Once the contractor is in place, interested parties will be contacted or be able to express interest in participating in the program.
This assistance is being provided through Wyoming’s Emerging Contaminants in Drinking Water Grant, which was funded through the Infrastructure Investments and Jobs Act of 2021, also known as the Bipartisan Infrastructure Law.
Testing for other emerging contaminants may also be conducted to help identify eligible projects for Wyoming’s Emerging Contaminants in Drinking Water Grant and emerging contaminant funding available through the State Revolving Loan Fund.
Public Water Systems Required to Comply with PFAS National Primary Drinking Water Regulation
The contractor will:
- Work with the Wyoming Department of Environmental Quality and the Environmental Protection Agency Region 8 Safe Drinking Water Act Public Water System Supervision Program to determine the PFAS National Primary Drinking Water Regulation initial monitoring requirements for each public water system. Initial monitoring will involve, prior to August 26, 2027, for each entry point to the distribution system, collection and analysis of either two samples five to seven months apart in a 12-month period or four samples two to four months apart in a 12-month period;
- Contact each public water system to determine their interest in participating in the PFAS Monitoring Assistance Program;
- Obtain permission to sample from public water systems interested in participating in the program;
- Visit each public water system 2-4 times to conduct the required monitoring;
- Inspect each entry point to the distribution system to identify PFAS-containing materials such as tapes, gaskets, seals, and coatings and provide recommendations on PFAS-free alternatives;
- Send the samples to a laboratory that is certified to analyze samples to meet the PFAS National Primary Drinking Water Regulation initial monitoring requirements;
- Receive the data from the laboratory, conduct quality review, and resample, if necessary;
- Provide results to the public water system;
- Provide recommended next steps, including assistance programs should PFAS be detected;
- Provide training to operators on how to conduct PFAS sampling;
- Submit the data to the Environmental Protection Agency on behalf of the public water system to meet the PFAS National Primary Drinking Water Regulation initial monitoring requirements; and
- Assist with public notifications should a public water system want to send notifications to their customers about the sampling results.
Public Water Systems Not Required to Comply with the PFAS National Primary Drinking Water Regulation
The contractor will:
- Contact each public water system to determine their interest in participating in the monitoring assistance program;
- Obtain permission to sample from public water systems interested in participating in the program;
- Visit each public water system to conduct monitoring;
- Inspect the system to identify PFAS-containing materials such as tapes, gaskets, seals, and coatings and provide recommendations on PFAS-free alternatives;
- Send the samples to a laboratory that is certified to analyze drinking water samples for PFAS;
- Receive the data from the laboratory, conduct quality review, and resample, if necessary;
- Provide results to the public water system;
- Provide recommended next steps, including assistance programs should PFAS be detected;
- Provide training to operators on how to conduct PFAS sampling;
- Assist with public notifications should the public water system need or want to send notifications to their customers to communicate the sampling results.
Private Wells In Proximity to Known or Potential PFAS Sources
The contractor will:
- Conduct outreach to private well owners to determine their interest in participating in the monitoring assistance program;
- Obtain permission to sample from private well owners interested in participating in the program;
- Visit each site to conduct monitoring;Â
- Inspect the system to identify PFAS-containing materials such as tapes, gaskets, seals, and coatings and provide recommendations on PFAS-free alternatives;
- Send the samples to a laboratory that is certified to analyze drinking water samples for PFAS;Â
- Receive the data from the laboratory, conduct quality review, resample, if necessary;
- Provide results to the private well owner; and
- Provide recommended next steps, including assistance programs should PFAS be detected.
