How does Portal Store compare with other water systems in Cochise County?
By EPA's size categories, Portal Store is a very small system (500 people or fewer). Cochise County has 104 active public water systems.

Nationally, the average active transient non-community water system reports serving 144 people, so Portal Store is well below that figure.

Does Portal Store have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in August 2024. The violations listed here began between June 1979 and August 2024. By type: 9 monitoring and reporting, 2 reporting and 1 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 7 as resolved and 5 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.
