How does Brinnonwold Assoc compare with other water systems in Jefferson County?
By EPA's size categories, Brinnonwold Assoc is a very small system (500 people or fewer). Jefferson County has 70 active public water systems.

Across Washington, the 4,705 active systems average 2,172 people each. Nationally, the average active transient non-community water system reports serving 144 people, so Brinnonwold Assoc is well below that figure.
What does “transient non-community water system” mean?

Washington has 1,913 active transient non-community water systems, 41% 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 Brinnonwold Assoc?

Does Brinnonwold Assoc have drinking water violations?
Of the 12 most recent violations in EPA's records, 2 are health-based, and the most recent began in October 2013. The violations listed here began between July 2004 and October 2013. By type: 10 monitoring and reporting and 2 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (3 of them). EPA lists 11 as archived and 1 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.
