Does Jasper Pws have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in April 2011. The violations listed here began between January 1994 and April 2011. By type: 11 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminants or rules involved are Lead and Copper Rule, Consumer Confidence Rule, Total coliform bacteria (TCR) and Chromium. 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.
