Water Quality Snapshot: CAPITAL REGION WATER

CAPITAL REGION WATER is a local-owned community water system that delivers drinking water to 66,540 residents in HARRISBURG, Pennsylvania (Dauphin County) through 20,778 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 145 total violations for this system , of which 12 (8%) 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 2023.

The most frequently cited contaminant at this system is Surface Water Treatment Rule, recorded in 26 violations (MR). This system was sampled under EPA's UCMR5 PFAS monitoring program and no PFAS compounds were detected above the minimum reporting level.

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. CAPITAL REGION WATER's 145 violations sit below the Pennsylvania average.
