Does Grand Mesa Lodge have drinking water violations?
EPA's records list 7 violations for this system; none is health-based, and the most recent began in January 2026. The violations listed here began between January 2017 and January 2026.

EPA lists 4 as resolved, 2 as unaddressed 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.

Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
