Does Navajo Dam Domestic Water Consumers Inc. have drinking water violations?
Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in February 2026. The violations listed here began between January 2022 and February 2026.

The contaminant or rule involved most often is Total trihalomethanes (TTHM) (4 of them). EPA lists 8 as resolved, 2 as archived and 2 as unaddressed. 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.

Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
