Does South Shores (Tui) have drinking water violations?
EPA's records list 7 violations for this system; 4 are health-based, and the most recent began in July 2013. The violations listed here began between July 2001 and July 2013.

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.
