Water Quality Snapshot: POCATELLO AIRPORT

POCATELLO AIRPORT is a local-owned non-transient non-community water system that delivers drinking water to 423 residents in POCATELLO, 10 through 43 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 379 total violations for this system , of which 0 (0%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 375 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 28 violations (MR). Under EPA's UCMR5 PFAS monitoring program, 1 PFAS compound was detected in samples collected from this system, with a maximum reported concentration of 48 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

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. POCATELLO AIRPORT's 379 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.
