PFAS in Drinking Water Monitoring Assistance Program
The PFAS in Drinking Water Monitoring Assistance Program provides cost-free support to public water systems and private well owners interested in testing drinking water for per- and polyfluoroalkyl substances (PFAS) and other emerging contaminants of interest. Funding for the program is provided by Wyoming’s Emerging Contaminant in Drinking Water Grant, which can provide support if PFAS or other emerging contaminants are detected.
The program can assist:
- Community water systems and non-transient non-community water systems meet initial monitoring requirements under the PFAS National Primary Drinking Water Regulation (PFAS NPDWR)
- Transient, non-community public water systems that are not subject to the PFAS National Primary Drinking Water Regulation
- Private well owners in proximity to known or suspected sources of PFAS
Sign Up
Sign up for the PFAS in Drinking Water Monitoring Assistance Program by completing the access agreement form. Public water systems should sign up by December 5, 2025. There is currently no deadline for private well owners to sign up.
The access agreement form can be completed:
- Online at: https://forms.microsoft.com/g/vJNpTp5TMC
- By downloading the form from the “Program Resources” tab on this webpage or requesting a copy from HydroGeoLogic, Inc. (HGL) at WDEQPFAS@hgl.com or (703) 326-7823.
- Return completed forms by email to WDEQPFAS@hgl.com or by mail to HydroGeoLogic, Inc., c/o Cheryl Delk, 200 Union Blvd, Suite 300, Lakewood, CO 80228.

Public Water Systems Required to Comply with PFAS National Primary Drinking Water Regulation
WDEQ’s contractor, HGL, can perform the following activities for public water systems required to comply with the PFAS National Primary Drinking Water Regulation.
- Visit each entry point to the distribution system two to four times to collect samples consistent with initial monitoring requirements of the PFAS National Primary Drinking Water Regulation. Sampling for other emerging contaminants such as 1,4-dioxane, perchlorate, aluminum, lithium, manganese, molybdenum, strontium, and vanadium can also be conducted.
- 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 PFAS (and potentially other emerging contaminant samples) to an approved laboratory for analysis.
- Conduct quality review of the data and resample, if necessary.
- Provide results to the public water system and WDEQ.
- Submit results to the U.S. Environmental Protection Agency by April 26, 2027, as required by the PFAS National Primary Drinking Water Regulation.
- Provide recommended next steps should PFAS or other emerging contaminants be detected, including information on financial assistance programs such as Wyoming’s Emerging Contaminants in Drinking Water Grant and Wyoming’s State Revolving Loan Fund.
- Provide hands-on and online training to operators on how to conduct PFAS sampling.
- Assist with public notifications, if requested.
Transient, Non-Community Public Water Systems Not Subject to the PFAS National Primary Drinking Water Regulation
WDEQ’s contractor, HGL, can perform the following activities for transient non-community public water systems not subject to the PFAS National Primary Drinking Water Regulation.
- Visit the transient non-community water system to conduct sampling for PFAS. Sampling for other emerging contaminants such as 1,4-dioxane, perchlorate, aluminum, lithium, manganese, molybdenum, strontium, and vanadium can also be conducted.
- Inspect each system to identify PFAS-containing materials such as tapes, gaskets, seals, and coatings and provide recommendations on PFAS-free alternatives.
- Send PFAS (and potentially other emerging contaminant samples) to a certified laboratory for analysis.
- Conduct quality review of the data and resample, if necessary.
- Provide results to the public water system and WDEQ.
- Provide recommended next steps should PFAS or other emerging contaminants be detected, including information on financial assistance programs such as Wyoming’s Emerging Contaminants in Drinking Water Grant and Wyoming’s State Revolving Loan Fund.
- Provide hands-on and online training to operators on how to conduct PFAS sampling.
- Assist with public notifications, if requested.
Private Wells In Proximity to Known or Potential PFAS Sources
WDEQ’s contractor, HGL, can perform the following activities for private well owners.
- Visit each private well to conduct PFAS sampling. Sampling for other emerging contaminants such as 1,4-dioxane, perchlorate, aluminum, lithium, manganese, molybdenum, strontium, and vanadium can also be conducted.
- Inspect each well to identify PFAS-containing materials such as tapes, gaskets, seals, and coatings and provide recommendations on PFAS-free alternatives.
- Send PFAS samples (and potentially other emerging contaminants) to a certified laboratory for analysis.
- Conduct quality review of the data and resample, if necessary.
- Provide sampling results to the private well owner and WDEQ.
- Provide recommended next steps should PFAS be detected, including information on financial assistance programs such as Wyoming’s Emerging Contaminants in Drinking Water Grant.
