Does Clarksville Pws have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in November 2023. The violations listed here began between November 1980 and November 2023. By type: 5 contaminant level above the legal limit, 4 monitoring and reporting, 1 required treatment not met, 1 monitoring and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Combined Radium (-226 and -228) (5 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.
