PFAS Monitoring in Kentucky: What Public Water Systems Need to Know

Kentucky’s ongoing PFAS monitoring efforts help communities better understand drinking water testing results and upcoming federal compliance requirements.

On June 25, 2024, the U.S. Environmental Protection Agency (EPA) finalized the National Primary Drinking Water Regulation (NPDWR) for six per- and polyfluoroalkyl substances, commonly known as PFAS. These “forever chemicals” raise concern for public drinking water systems. They break down slowly and can remain in the environment over time.

Under the federal rule, public water systems with PFAS levels above the established limits must take corrective action. First, they must complete initial monitoring by 2027. Then, if PFAS levels exceed the Maximum Contaminant Levels, they currently must implement solutions by 2029.

Kentucky PFAS Testing and Monitoring

The Kentucky Division of Water (DOW) has been collecting PFAS samples from public drinking water systems across the state. These systems produce or treat drinking water for Kentucky communities. As a result, continued monitoring helps show where PFAS may be present and how results change over time.

In addition, DOW provides an interactive PFAS Data Viewer. The tool makes sampling locations and available public water system results easier to access. The Kentucky PFAS Data Viewer allows residents, utilities, and community leaders to explore where DOW has sampled for PFAS. It also allows users to review reported testing results. However, DOW may update or revise the data. For that reason, residents should contact their local water provider for the most current drinking water quality information.
