Does G & W WSC have drinking water violations?
Of the 12 most recent violations in EPA's records, 11 are health-based, and the most recent began in October 2025. The violations listed here began between June 2024 and October 2025. By type: 11 contaminant level above the legal limit and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Gross alpha (excluding radon and uranium) (6 of them). EPA lists 6 as archived and 6 as resolved. 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.
