Does Koa Campground Store have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in May 2023. The violations listed here began between April 1996 and May 2023. By type: 6 monitoring and reporting, 2 public notice, recordkeeping or other, 2 monitoring, 1 required treatment not met and 1 contaminant level above the legal limit. 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.
