Based on the latest laboratory testing, Per-and Polyfluoroalkyl Substances (PFAS) are NOT detected in City of Golden Water.

On June 15, 2022, the U.S. Environmental Protection Agency (EPA) released drinking water health advisories for four Per-and Polyfluoroalkyl Substances. The EPA’s health advisories provide states and water utilities, including the City of Golden, with a reference point as they evaluate potential contamination and appropriate responses to assure the safety of drinking water.

According to the EPA, per-and polyfluoroalkyl substances, also called PFAS, are a group of chemicals used to make carpets, clothing, furniture, and cookware resistant to water, grease and stains. These substances are also used to fight fires at airfields, are included in some industrial processes, and may contribute to various health impacts.

In anticipation of the updated EPA health advisories, the City of Golden conducted sampling for PFAS chemicals to better understand where they occur and at what levels. Through an accredited third-party laboratory and using the best-available EPA-approved analytical methods, the City of Golden has not detected PFAS, including PFOS, or PFOA in untreated source water or in treated drinking water. The city is working with the Colorado Department of Public Health and Environment and other local utilities to better understand the implications of the EPA’s health advisories and we will continue to update as information becomes available. You can read the lab results in the report that we are making available to the public.

The City of Golden is committed to the protection of public health, and we share the EPA’s desire to keep harmful levels of PFAS out of our drinking water. To better understand PFAS and the associated environmental and health risks, please visit the EPA’s Per-and Polyfluoroalkyl Substances webpage for more information (
