With regard to our drinking water supply, PWSD and other water utilities across the country are scheduled to begin monitoring for 29 different PFAS between 2023 and 2025 under the EPA’s fifth Unregulated Contaminants Monitoring Rule (UCMR).
Under the UCMR, every five years the EPA is required to issue a list of unregulated contaminants to be monitored by water systems under the Safe Drinking Water Act. This monitoring provides EPA and other parties with scientifically valid data on the national occurrence of these contaminants in drinking water. As part of the testing, PWSD will report any findings on our annual Consumer Confidence Report. We will rely on the EPA and the Colorado Department of Public Health and Environment (CDPHE) for further guidance on any regulatory updates and necessary actions as science progresses.
With regard to our wastewater operations, future discharge permit requirements could impact PWSD’s pretreatment program, treatment processes, and biosolids program.
