Does Stillwater Valley Golf Club have drinking water violations?
EPA's records list 10 violations for this system; 6 are health-based, and the most recent began in November 2011. The violations listed here began between April 1995 and November 2011. By type: 6 contaminant level above the legal limit and 4 monitoring and reporting. The contaminant or rule involved most often is Total coliform bacteria (TCR) (8 of them). EPA lists 9 as resolved 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.
