Does Usace Philippi Park have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in May 2025. The violations listed here began between June 2009 and May 2025. By type: 7 monitoring, 4 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Revised Total Coliform Rule (8 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.
