How does Wal-Mart compare with other water systems in Ketchikan Gateway Borough County?
By EPA's size categories, Wal-Mart is a very small system (500 people or fewer). Ketchikan Gateway Borough County has 22 active public water systems. Its population served is well below the county average of 560 people per system, and accounts for 0.9% of the 12,315 people reported by systems filed under the county. Across Alaska, the 1,322 active systems average 653 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Wal-Mart 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. Alaska has 227 active non-transient non-community water systems, 17% of the state's 1,322 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,054 Alaska systems (80%) list groundwater as their primary source.
Who owns and regulates Wal-Mart?
EPA lists Wal-Mart as privately owned. The AK state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 15 of the 22 active systems in Ketchikan Gateway Borough County (68%) are also privately owned.
