RIVERTON CITY WATER SYSTEM serves 45,600 people in EAGLE MOUNTAIN, Utah using Surface Water water sources. It has 694 recorded EPA violations, including 42 health-based violations. PFAS "forever chemicals" were detected in UCMR5 testing (1 compound found).

Water Quality Snapshot: RIVERTON CITY WATER SYSTEM

RIVERTON CITY WATER SYSTEM is a local-owned community water system that delivers drinking water to 45,600 residents in EAGLE MOUNTAIN, Utah (Salt Lake County) through 10,575 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 694 total violations for this system , of which 42 (6%) are health-based — meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 641 monitoring and reporting violations are on file. The most recent violation on record dates to 2019.

The most frequently cited contaminant at this system is Coliform (TCR), recorded in 42 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 16 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. RIVERTON CITY WATER SYSTEM's 694 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.
