Does Valley View Subdivision (Dekalb) have drinking water violations?
EPA's records list 11 violations for this system; 2 are health-based, and the most recent began in August 2025. The violations listed here began between June 1977 and August 2025. By type: 4 monitoring and reporting, 3 public notice, recordkeeping or other, 2 monitoring, 1 required treatment not met and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Revised Total Coliform Rule (2 of them). EPA lists 7 as resolved, 3 as archived and 1 as unaddressed. 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.

Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
