Does Newdale Grand Valley Wc have drinking water violations?
EPA's records list 11 violations for this system; 3 are health-based, and the most recent began in April 2026. The violations listed here began between January 1998 and April 2026. By type: 8 monitoring and reporting and 3 contaminant level above the legal limit. The contaminant or rule involved most often is Combined Radium (-226 and -228) (5 of them). EPA lists 8 as resolved, 2 as unaddressed and 1 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
