Does Martindale WSC have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in January 2026. The violations listed here began between March 2007 and January 2026. By type: 6 monitoring and reporting and 6 contaminant level above the legal limit. The contaminant or rule involved most often is Interim Enhanced Surface Water Treatment Rule (4 of them). EPA lists 9 as resolved and 3 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.
