Water Quality Snapshot: Penrose WD

Penrose WD is a local-owned community water system that delivers drinking water to 3,149 residents in Penrose, Colorado (Fremont County) through 1,767 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 64 total violations for this system , of which 18 (28%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 42 monitoring and reporting violations are on file. The most recent violation on record dates to 2023.

The most frequently cited contaminant at this system is Surface Water Treatment Rule, recorded in 14 violations (TT, health-based). This system has not yet been sampled under EPA's UCMR5 PFAS monitoring program, so no PFAS detection data is available here.

Across Colorado, EPA tracks 2,193 public water systems serving 7,473,456 people, with 238,796 cumulative violations and 30,589 health-based violations on record. About 93% of systems in the state carry at least one violation, and state-wide the average per system is 108.9 violations.
