Homes, apartments and mobile-home parks are served by these. Wyoming has 332 active community water systems, 43% of the state's 775 active systems. Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 79 Wyoming systems (10%) list purchased surface water as their primary source.
Who owns and regulates Town of Sinclair?

The WY state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 10 of the 25 active systems in Carbon County (40%) are also owned by a local government.
Does Town of Sinclair have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in September 2021. The violations listed here began between May 1998 and September 2021. By type: 4 required treatment not met, 3 monitoring, 3 monitoring and reporting and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Surface Water Treatment Rule (5 of them). EPA lists 11 as resolved and 1 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
