Does Southside Northside Water Assn have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2025. The violations listed here began between April 2021 and October 2025. By type: 7 public notice, recordkeeping or other and 5 monitoring and reporting. The contaminant or rule involved most often is Public Notice (4 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.
