Does Walpole Water Dept have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2014. The violations listed here began between January 1997 and January 2014. By type: 10 monitoring and reporting and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (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.
