Does Timber Trails Homeowners Association have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in August 2025. The violations listed here began between September 1980 and August 2025. By type: 7 monitoring and reporting and 5 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 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.
