The filters remove PFAS and other chemicals in the water. TOP RIGHT: Pipes attached to granular activated carbon filters are seen at facility, which started testing in 2021 for PFAS on a regular basis. BOTTOM RIGHT: Pipes run with water through Plum Creek Water Purification Facility. Castle Rock and other Colorado communities are taking legal action against the manufactures of PFAS, due in part to the cost of filtering the chemicals from drinking water.
