What does “community water system” mean?

Homes, apartments and mobile-home parks are served by these. North Carolina has 2,031 active community water systems, 40% of the state's 5,087 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 4,566 North Carolina systems (90%) list groundwater as their primary source.
Who owns and regulates Riverstone?

Does Riverstone have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in December 2023. The violations listed here began between July 1985 and December 2023. By type: 7 monitoring and reporting, 3 contaminant level above the legal limit, 1 monitoring and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Haloacetic acids (HAA5) (2 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.
