Colorado water district safeguards water supply from PFAS

The South Adams County Water and Sanitation District (District) in Commerce City, Colorado, is enhancing its water treatment process to meet EPA Health Advisory Levels (HALs) for per- and polyfluoroalkyl substances (PFAS) in drinking water supplies.

Deemed “forever chemicals,” PFAS is a group of human-made chemicals used in many applications, including stain- and water-resistant fabrics and carpeting, cleaning products, paints, and firefighting foams. PFAS are resistant to grease, oil, water, and heat and may enter water supplies from landfills, the use of firefighting foam (e.g., at airports, fire training facilities, petroleum fires, etc.), industrial sites, and wastewater treatment plant discharge.
