Water Quality Snapshot: G M WSC

G M WSC is a local-owned community water system that delivers drinking water to 11,220 residents in HEMPHILL, Texas (Sabine County) through 3,511 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 189 total violations for this system , of which 133 (70%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 14 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 TTHM, recorded in 61 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 11.2 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Texas, EPA tracks 7,351 public water systems serving 33,253,313 people, with 746,210 cumulative violations and 162,945 health-based violations on record. About 90% of systems in the state carry at least one violation, and state-wide the average per system is 101.5 violations. G M WSC's 189 violations sit above the Texas average. Statewide, 1,068 of 1,147 UCMR5-tested systems have reported PFAS detections (93.1%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
