Water Quality Snapshot: MIDVALE CITY WATER SYSTEM

MIDVALE CITY WATER SYSTEM is a local-owned community water system that delivers drinking water to 33,005 residents in EAGLE MOUNTAIN, Utah (Salt Lake County) through 7,908 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 834 total violations for this system , of which 33 (4%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 789 monitoring and reporting violations are on file. The most recent violation on record dates to 2022.

The most frequently cited contaminant at this system is Coliform (TCR), recorded in 32 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 86 ppt. PFAS are persistent synthetic chemicals linked to health effects at very low exposure levels.

Across Utah, EPA tracks 1,068 public water systems serving 3,870,776 people, with 169,784 cumulative violations and 10,671 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 159 violations. MIDVALE CITY WATER SYSTEM's 834 violations sit above the Utah average. Statewide, 91 of 129 UCMR5-tested systems have reported PFAS detections (70.5%). All figures above are sourced directly from EPA SDWIS and UCMR5 public data releases and are updated as EPA publishes new reporting cycles.
