Does Grouse Point Water Company LLC 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 2020. The violations listed here began between October 2008 and January 2020. By type: 11 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Nitrate (2 of them). EPA lists 10 as resolved and 2 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.
