Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 121 Tennessee systems (8.7%) list purchased surface water as their primary source.
Who owns and regulates Siam Utility District?

The TN state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 8 of the 15 active systems in Carter County (53%) are also owned by a local government.
Does Siam Utility District have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2025. The violations listed here began between July 2021 and July 2025. By type: 6 public notice, recordkeeping or other and 6 monitoring and reporting. The contaminant or rule involved most often is Consumer Confidence Rule (6 of them). EPA lists 7 as resolved, 3 as unaddressed and 2 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
