How does Isle Aire Beach Association compare with other water systems in Whatcom County?

By EPA's size categories, Isle Aire Beach Association is a very small system (500 people or fewer). Whatcom County has 183 active public water systems.

Nationally, the average active community water system reports serving 6,703 people, so Isle Aire Beach Association is well below that figure.

Groundwater means the system draws its water from wells or springs fed by underground aquifers. 4,370 Washington systems (93%) list groundwater as their primary source.

Who owns and regulates Isle Aire Beach Association?

Does Isle Aire Beach Association have drinking water violations?

Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in January 2025. The violations listed here began between January 2002 and January 2025. By type: 8 monitoring and reporting and 4 contaminant level above the legal limit. The contaminant or rule involved most often is Arsenic (4 of them). EPA lists 8 as resolved and 4 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.
