How does Diamond Pet Foods compare with other water systems in Osage County?
By EPA's size categories, Diamond Pet Foods is a very small system (500 people or fewer). Osage County has 13 active public water systems. Its population served is about 64% below the county average of 633 people per system, and accounts for 2.8% of the 8,225 people reported by systems filed under the county. Across Missouri, the 2,943 active systems average 2,049 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Diamond Pet Foods is about half of 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. Missouri has 228 active non-transient non-community water systems, 7.7% of the state's 2,943 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,521 Missouri systems (86%) list groundwater as their primary source.
Who owns and regulates Diamond Pet Foods?
EPA lists Diamond Pet Foods as privately owned. The MO state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 4 of the 13 active systems in Osage County (31%) are also privately owned.
