Water Quality Snapshot: EUNICE WATER SUPPLY SYSTEM

EUNICE WATER SUPPLY SYSTEM is a local-owned community water system that delivers drinking water to 4,487 residents in EUNICE, New Mexico (Lea County) through 1,608 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 63 total violations for this system , of which 17 (27%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 32 monitoring and reporting violations are on file. The most recent violation on record dates to 2020.

The most frequently cited contaminant at this system is Coliform (TCR), recorded in 13 violations (MCL, 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 23.8 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across New Mexico, EPA tracks 1,037 public water systems serving 2,027,497 people, with 154,522 cumulative violations and 38,650 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 149 violations. EUNICE WATER SUPPLY SYSTEM's 63 violations sit below the New Mexico average. Statewide, 70 of 72 UCMR5-tested systems have reported PFAS detections (97.2%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
