Does Stockton Town Water System have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in May 2016. The violations listed here began between January 2011 and May 2016. By type: 10 monitoring and reporting, 1 monitoring and 1 required treatment not met. The contaminant or rule involved most often is Nitrate (3 of them). EPA lists 11 as resolved and 1 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.
