Perfluorinated compounds in Colorado

 
Through the EPA's monitoring program, perfluorinated compounds were found in some Colorado water supply sources. The first instance of perfluorinated compounds in Colorado water was in El Paso County. On May 19, 2016 the EPA issued a new health advisory level for perfluorinated compounds.
 
Drinking water delivered to your tap from a public water system can be from one of these sources. The water can be treated water directly from groundwater wells, water that is blended from multiple wells or with treated reservoir water, or solely from treated reservoir water. 

Specific perfluorinated compounds identified:
•    PFBS (Perfluorobutanesulfonic acid)
•    PFHpA (Perfluoroheptanoic acid)
•    PFHxS (Perfluorohexane sulfonic acid)
•    PFNA (Perfluorononanoic acid)
•    PFOA (Perfluorooctanoic acid)
•    PFOS (Perfluorooctansulfonic acid)
