Water Quality Snapshot: VEOLIA MECHANICSBURG

VEOLIA MECHANICSBURG is a private-owned community water system that delivers drinking water to 45,013 residents in HARRISBURG, Pennsylvania (Cumberland County) through 14,601 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 98 total violations for this system , of which 12 (12%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 77 monitoring and reporting violations are on file. The most recent violation on record dates to 2021.

The most frequently cited contaminant at this system is Total Haloacetic Acids (HAA5), recorded in 12 violations (MCL, health-based). Under EPA's UCMR5 PFAS monitoring program, 6 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 0.0114 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. VEOLIA MECHANICSBURG's 98 violations sit below the Pennsylvania average.
