How does West Salome Water Association compare with other water systems in La Paz County?
By EPA's size categories, West Salome Water Association is a very small system (500 people or fewer). La Paz County has 84 active public water systems.

Across Arizona, the 1,769 active systems average 4,369 people each. Nationally, the average active transient non-community water system reports serving 144 people, so West Salome Water Association is well below that figure.

Does West Salome 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 2023. The violations listed here began between May 1988 and November 2023. By type: 11 monitoring and reporting and 1 reporting. The contaminant or rule involved most often is Fluoride (2 of them). EPA lists 9 as resolved and 3 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.
