GRAND JUNCTION, Colo. (KREX) — The U.S. Environmental Protection Agency (EPA) released information about its final rule setting drinking water standards for per- and polyfluoroalkyl substances (PFAS) on April 10. The EPA rule finalized the Microliters of 4.0 parts per trillion (ppt) for both perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS).

The Colorado Department of Public Health and Environment grant program gave the City of Grand Junction funding to test its local water for the past two years. They reported no findings of those chemicals.

Ute Water and Clifton Water Systems also reported negligible levels of PFAS as did most western Colorado counties with two exceptions. Garfield and La Plata County PFAS levels were low on Colorado Public Health and Environment maps except around the towns of Silt, Rifle and Parachute where a higher potential for PFAS contamination in the groundwater was noted.
