How does Crestview Water Association compare with other water systems in Adams County?
By EPA's size categories, Crestview Water Association is a very small system (500 people or fewer). Adams County has 49 active public water systems.

Does Crestview Water Association have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in November 2025. The violations listed here began between January 2008 and November 2025. By type: 10 monitoring and reporting and 2 monitoring. The contaminant or rule involved most often is Revised Total Coliform Rule (2 of them). EPA lists 8 as archived and 4 as resolved. 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. 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.
