PFAS Information

February 2022 Update:

As part of Safe Drinking Water Act the EPA coordinates the Unregulated Contaminant Monitoring Rule (UCMR) program. Every five (5) years drinking water companies are required to collect samples of the drinking water that are analyzed for priority unregulated contaminants.

Analysis from these samples provide the EPA with scientifically-valid data on these contaminants that are currently unregulated in drinking water. The data improves EPA’s understanding of frequency at which they are found and at what levels and helps ensure science-based decision making.

Samples will be collected during 2023-2025.

Once we have collected samples for UCMR 5 GU will share that data in our Water Quality Report and on GU’s website detailing Perfluorinated Chemical testing.
