Water Quality Snapshot: Idaho Materials and Construction

Idaho Materials and Construction is a private-owned non-transient non-community water system that delivers drinking water to 33 residents in Pocatello, Idaho (Bannock County) through 2 service connections. Its water is drawn from groundwater sources. EPA's Safe Drinking Water Information System records 92 total violations for this system , of which 1 (1%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 90 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 20 violations (MR). This system has not yet been sampled under EPA's UCMR5 PFAS monitoring program, so no PFAS detection data is available here.

Across Idaho, EPA tracks 2,005 public water systems serving 1,743,912 people, with 104,850 cumulative violations and 19,965 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 52.3 violations. Statewide, 40 of 60 UCMR5-tested systems have reported PFAS detections (66.7%).

Idaho Materials and Construction's 92 violations sit above the Idaho average.

All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
