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.

Does Cumberland Heights U.D. have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in March 2019. The violations listed here began between December 1992 and March 2019. By type: 9 monitoring and reporting, 2 contaminant level above the legal limit and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 8 as resolved and 4 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.
