Per- and polyfluoroalkyl substances (PFAS) are a group of human-made chemicals that have been manufactured and used in a variety of industries in the United States since the 1940s, and found in many consumer products like cookware, food packaging, and stain repellants. PFAS manufacturing and processing facilities, airports, and military installations that use firefighting foams are some of the main sources of PFAS.
PFAS have not been detected in our drinking water.
In 2024, as part of the U.S. Environmental Protection Agency’s (EPA’s) 5th Unregulated Contaminants Monitoring Rule (UCMR5), we sampled for the 29 PFOS and PFOA compounds as well as lithium; we have had no detections to date. The results are published by the EPA, in our Consumer Confidence Report, and in our Water Quality Analyses report, which is a comprehensive listing of all our annual testing results. Both reports are available on our Water Quality Reports page.
We will continue to monitor our drinking water sources for contaminants such as PFAS and maintain our robust source water protection programs to continue to bring you a reliable, high-quality water supply at the best value.
