Does New Richmond Estates have drinking water violations?
EPA's records list 10 violations for this system; 7 are health-based, and the most recent began in October 2020. The violations listed here began between January 1979 and October 2020. By type: 7 contaminant level above the legal limit and 3 monitoring and reporting. The contaminant or rule involved most often is Nitrate (5 of them). EPA lists 5 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.
