How does Wauna Lake compare with other water systems in Skamania County?

By EPA's size categories, Wauna Lake is a very small system (500 people or fewer). Skamania County has 56 active public water systems. Its population served is well below the county average of 335 people per system, and accounts for 0.4% of the 18,736 people reported by systems filed under the county. 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 Wauna Lake is about half of 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 Wauna Lake?

EPA lists Wauna Lake 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. 24 of the 56 active systems in Skamania County (43%) are also privately owned.

Does Wauna Lake have drinking water violations?

EPA's records list 10 violations for this system; none is health-based, and the most recent began in June 2020. The violations listed here began between August 2003 and June 2020. By type: 7 monitoring and reporting and 3 monitoring. The contaminant or rule involved most often is Nitrate (4 of them). EPA lists 9 as resolved and 1 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.
