Does Cortland (C) have drinking water violations?
EPA's records list 7 violations for this system; 5 are health-based, and the most recent began in December 2010. The violations listed here began between September 1993 and December 2010.

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.
