Does Burbank Irrigation District 4 have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in May 2020. The violations listed here began between October 1984 and May 2020. By type: 6 contaminant level above the legal limit, 5 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Nitrate (4 of them). EPA lists 7 as archived and 5 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.
