Does Dardanelles Resort 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 2010. The violations listed here began between August 1984 and January 2010. By type: 10 monitoring and reporting and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (6 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. 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.
