Does Knickerbocker Liquor Locker have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in December 2016. The violations listed here began between October 2001 and December 2016. By type: 4 public notice, recordkeeping or other, 3 contaminant level above the legal limit, 3 monitoring and reporting, 1 required treatment not met and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 7 as archived and 5 as resolved.

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.
