Does Timberlane Water Association have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in August 2025. The violations listed here began between April 1994 and August 2025. By type: 9 monitoring and reporting, 2 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is Nitrite (2 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.
