Does Wareham Fire District have drinking water violations?
Of the 12 most recent violations in EPA's records, 9 are health-based, and the most recent began in January 2020. The violations listed here began between August 2007 and January 2020. By type: 8 contaminant level above the legal limit, 2 public notice, recordkeeping or other, 1 required treatment not met and 1 reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 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.
