PFAS and Drinking Water

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.

Although PFAS compounds are currently unregulated in drinking water, City Utilities and other water utilities have been collecting samples to help the Environmental Protection Agency (EPA) develop possible new regulations.  Growing scientific and public concern about PFAS has prompted the EPA to propose 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 that the EPA is proposing to regulate. This includes the most recent testing completed by City Utilities in June 2023.

We are providing this information and additional links on this page to help you understand and stay current on the latest information about PFAS. The EPA regulations were released on April 10, 2024. A summary is available here.
