Does Gateway Mobile Home Park have drinking water violations?
EPA's records list 11 violations for this system; 1 is health-based, and the most recent began in December 2012. The violations listed here began between October 1980 and December 2012. By type: 7 public notice, recordkeeping or other, 3 monitoring and reporting and 1 contaminant level above the legal limit. The contaminant or rule involved most often is Gross alpha (excluding radon and uranium) (2 of them). EPA lists 9 as archived and 2 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.
