Does Isleta Eastside have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in December 2016. The violations listed here began between November 1997 and December 2016. By type: 7 monitoring and reporting, 4 public notice, recordkeeping or other and 1 required treatment not met. 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.
