Does Elmer Pws have drinking water violations?
EPA's records list 5 violations for this system; 2 are health-based, and the most recent began in July 2006. The violations listed here began between October 1979 and July 2006. By type: 2 public notice, recordkeeping or other, 2 contaminant level above the legal limit and 1 monitoring and reporting. The contaminant or rule involved most often is Consumer Confidence Rule (2 of them). EPA lists 4 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.
