Water Quality Snapshot: ROCKWOOD BORO MUNI AUTH

ROCKWOOD BORO MUNI AUTH is a local-owned community water system that delivers drinking water to 1,250 residents in ROCKWOOD, Pennsylvania (Somerset County) through 500 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 150 total violations for this system , of which 0 (0%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 117 monitoring and reporting violations are on file. The most recent violation on record dates to 2024.

The most frequently cited contaminant at this system is Coliform (TCR), recorded in 18 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 1 PFAS compound was detected in samples collected from this system, with a maximum reported concentration of 98 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Pennsylvania, EPA tracks 7,701 public water systems serving 12,630,061 people, with 1,159,868 cumulative violations and 68,517 health-based violations on record. About 97% of systems in the state carry at least one violation, and state-wide the average per system is 150.6 violations. ROCKWOOD BORO MUNI AUTH's 150 violations sit below the Pennsylvania average. Statewide, 224 of 389 UCMR5-tested systems have reported PFAS detections (57.6%).
