Does Willow Berm Marina have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in August 2016. The violations listed here began between December 1983 and August 2016. By type: 10 public notice, recordkeeping or other, 1 monitoring and 1 monitoring and reporting. The contaminants or rules involved are Revised Total Coliform Rule and Total coliform bacteria (TCR). EPA lists 11 as archived and 1 as resolved. 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. 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.
