A further 35 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 Groundwater Rule, recorded in 41 violations (TT, health-based). Under EPA's UCMR5 PFAS monitoring program, 1 PFAS compound was detected in samples collected from this system, with a maximum reported concentration of 17 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. HOMER WATER SYSTEM's 148 violations sit above the Louisiana average. Statewide, 218 of 265 UCMR5-tested systems have reported PFAS detections (82.3%).
