Water Quality Snapshot: MISSION WATER SYSTEM

MISSION WATER SYSTEM is a native american-owned community water system that delivers drinking water to 1,500 residents in MISSION, 08 through 550 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 15 total violations for this system , of which 3 (20%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 10 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 Coliform (TCR), recorded in 3 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 69 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across 08, EPA tracks 160 public water systems serving 144,980 people, with 13,068 cumulative violations and 1,547 health-based violations on record. About 96% of systems in the state carry at least one violation, and state-wide the average per system is 81.7 violations. MISSION WATER SYSTEM's 15 violations sit below the 08 average. Statewide, 10 of 13 UCMR5-tested systems have reported PFAS detections (76.9%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
