Water Quality Snapshot: FARMERVILLE WATER SYSTEM

FARMERVILLE WATER SYSTEM is a local-owned community water system that delivers drinking water to 5,400 residents in FARMERVILLE, Louisiana (Union Parish County) through 1,800 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 326 total violations for this system , of which 290 (89%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 18 monitoring and reporting violations are on file. The most recent violation on record dates to 2025.

The most frequently cited contaminant at this system is TTHM, recorded in 246 violations (MCL, health-based). Under EPA's UCMR5 PFAS monitoring program, 2 PFAS compounds were detected in samples collected from this system, with a maximum reported concentration of 0.0048 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Louisiana, EPA tracks 1,234 public water systems serving 5,316,532 people, with 115,060 cumulative violations and 62,164 health-based violations on record. About 93% of systems in the state carry at least one violation, and state-wide the average per system is 93.2 violations. FARMERVILLE WATER SYSTEM's 326 violations sit above the Louisiana average. Statewide, 218 of 265 UCMR5-tested systems have reported PFAS detections (82.3%).
