Does Maze Blvd Mobilehome Park have drinking water violations?
EPA's records list 9 violations for this system; 2 are health-based, and the most recent began in July 2025. The violations listed here began between October 1980 and July 2025. By type: 7 monitoring and reporting and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 5 as resolved, 2 as unaddressed and 2 as archived.

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.
