How does Briarwood Water System compare with other water systems in Island County?

By EPA's size categories, Briarwood Water System is a very small system (500 people or fewer). Island County has 307 active public water systems. Its population served is well below the county average of 335 people per system, and accounts for less than 0.1% of the 102,977 people reported by systems filed under the county. Across Washington, the 4,705 active systems average 2,172 people each. Nationally, the average active community water system reports serving 6,703 people, so Briarwood Water System is well below that figure.

What does “community water system” mean?

A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Washington has 2,392 active community water systems, 51% of the state's 4,705 active systems. 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 Briarwood Water System?

EPA lists Briarwood Water System as privately owned. The WA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 274 of the 307 active systems in Island County (89%) are also privately owned.

Does Briarwood Water System have drinking water violations?

Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in October 2024. The violations listed here began between March 1998 and October 2024. By type: 7 monitoring and reporting, 3 contaminant level above the legal limit, 1 public notice, recordkeeping or other and 1 monitoring. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (5 of them). EPA lists 6 as resolved, 4 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. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
