Does Holland Tn Sanitary Dist have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in July 2017. The violations listed here began between January 2008 and July 2017. By type: 6 public notice, recordkeeping or other, 4 monitoring and reporting and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Public Notice (5 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.
