City Utilities is committed to providing safe, high-quality drinking water that supports public health. City Utilities has consistently kept abreast of the concerns related to per- and polyfluoroalkyl substances (PFAS). We began testing for the chemicals in 2014.
The Environmental Protection Agency (EPA) released new regulations earlier this year, that will take effect in 2027. City Utilities and other water utilities have collected samples to help the EPA develop the new rules. Growing scientific and public concern about PFAS prompted the new drinking water regulations regarding six PFAS compounds: PFOA, PFOS, PFNA, PFHxS, PFBS and HFPO-DA.
City Utilities’ testing since 2014 has not detected any of the six chemicals in our drinking water at the Three Rivers Filtration Plant that are now regulated. This includes the most recent testing completed by City Utilities in June 2024.
We are providing this information and additional links on this page to help you understand and stay updated on the latest information about PFAS. The EPA regulations summary is available here.
The Environmental Protection Agency continues to evaluate PFAS and future regulations. Current plans are in place through 2024.
City Utilities, and other large regional utilities work with the EPA on PFAS testing. Smaller Indiana utilities work with the Indiana Department of Environmental Management (IDEM) for testing.
