What does “transient non-community water system” mean?

Virginia has 1,133 active transient non-community water systems, 47% of the state's 2,420 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,089 Virginia systems (86%) list groundwater as their primary source.
Who owns and regulates Prospect Hill?

Does Prospect Hill have drinking water violations?
EPA's records list 7 violations for this system; 2 are health-based, and the most recent began in July 2014. The violations listed here began between June 1979 and July 2014. By type: 5 monitoring and reporting and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 4 as resolved and 3 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.
