Water Quality Snapshot: CORPORATION OF SHEPHERDSTOWN

CORPORATION OF SHEPHERDSTOWN is a local-owned community water system that delivers drinking water to 4,300 residents in SHEPHERDSTOWN, West Virginia (Jefferson County) through 1,872 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 363 total violations for this system , of which 76 (21%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 250 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 32 violations (MCL, health-based). Under EPA's UCMR5 PFAS monitoring program, 3 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 0.004 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across West Virginia, EPA tracks 774 public water systems serving 1,597,057 people, with 187,590 cumulative violations and 11,480 health-based violations on record. About 99% of systems in the state carry at least one violation, and state-wide the average per system is 242.4 violations. CORPORATION OF SHEPHERDSTOWN's 363 violations sit above the West Virginia average. Statewide, 46 of 102 UCMR5-tested systems have reported PFAS detections (45.1%).
