Water Quality Snapshot: METLAKATLA

METLAKATLA is a native american-owned community water system that delivers drinking water to 1,575 residents in METLAKATLA, 10 through 565 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 368 total violations for this system , of which 111 (30%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 203 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 Long Term 2 Enhanced Surface Water Treatment Rule, recorded in 66 violations (TT, health-based). This system has not yet been sampled under EPA's UCMR5 PFAS monitoring program, so no PFAS detection data is available here.

Across 10, EPA tracks 158 public water systems serving 142,574 people, with 31,953 cumulative violations and 1,055 health-based violations on record. About 98% of systems in the state carry at least one violation, and state-wide the average per system is 202.2 violations. METLAKATLA's 368 violations sit above the 10 average. Statewide, 2 of 10 UCMR5-tested systems have reported PFAS detections (20%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
