How does Columbia Cedar compare with other water systems in Ferry County?
By EPA's size categories, Columbia Cedar is a very small system (500 people or fewer). Ferry County has 33 active public water systems. Its population served is about 61% below the county average of 182 people per system, and accounts for 1.2% of the 5,998 people reported by systems filed under the county. Across Washington, the 4,705 active systems average 2,172 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Columbia Cedar is well below that figure.
What does “non-transient non-community water system” mean?
A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Washington has 400 active non-transient non-community water systems, 8.5% 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 Columbia Cedar?
EPA lists Columbia Cedar 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 33 active systems in Ferry County (73%) are also privately owned.
