Does Odebolt Water Supply have drinking water violations?
Of the 12 most recent violations in EPA's records, 10 are health-based, and the most recent began in August 2011. The violations listed here began between July 1980 and August 2011. By type: 10 contaminant level above the legal limit and 2 monitoring and reporting. The contaminant or rule involved most often is Combined Radium (-226 and -228) (8 of them). EPA lists 9 as archived and 3 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.
