Does Elm Hill Water District have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in July 2023. The violations listed here began between January 1992 and July 2023. By type: 7 monitoring and reporting, 4 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Consumer Confidence Rule (4 of them). EPA lists 7 as resolved and 5 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.
