Does Calamity Peak Lodge have drinking water violations?
EPA's records list 8 violations for this system; 1 is health-based, and the most recent began in October 2010. The violations listed here began between June 1990 and October 2010.

The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 5 as resolved and 3 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.
