Water Quality Snapshot: Snake River Mobile Home Park
Snake River Mobile Home Park is a private-owned community water system that delivers drinking water to 100 residents in Dallas, Wyoming (Teton County) through 26 service connections. Its water is drawn from surface water sources. EPA's Safe Drinking Water Information System records 457 total violations for this system , of which 9 (2%) are health-based, meaning a contaminant exceeded an EPA Maximum Contaminant Level or a required treatment technique failed. A further 434 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 29 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 Wyoming, EPA tracks 766 public water systems serving 639,288 people, with 32,465 cumulative violations and 4,023 health-based violations on record. About 95% of systems in the state carry at least one violation, and state-wide the average per system is 42.4 violations.
