PFAS education center
Per- and polyfluoroalkyl substances (PFAS) are a group of thousands of manmade chemicals that are used to make carpets, clothing, fabrics for furniture, food packaging, cookware, and other materials to make them non-stick and/or resistant to water, oil, and stains. They are also used in a number of industrial processes and firefighting activities. Chemical manufacturers are the original source of PFAS chemicals.
PFAS have been detected in the Orange County Groundwater Basin, which supplies 77% of the drinking water supply to north and central Orange County. Over the past several years, the science on PFAS and its impacts to the environment and public health have prompted regulatory actions. Despite playing no role in releasing PFAS into the environment, cities and water agencies must find ways to remove it from their local water supplies. Adding to this burden is the threat of financial liability for water and wastewater agencies, therefore impacting our ratepayers. Our ratepayers should not have to bear the cost of cleanup.
OCWD and its water retailers provide some of the cleanest drinking water in the world. The District is proactively and swiftly addressing PFAS in Orange County and is committed to sharing information and resources with its communities.
