Does Keensburg have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in August 2001. The violations listed here began between July 1995 and August 2001. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminants or rules involved are Total coliform bacteria (TCR), Lead and Copper Rule, 1,1-Dichloroethylene and trans-1,2-Dichloroethylene. 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. 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.
