How does Grove Medical Center compare with other water systems in Lake County?
By EPA's size categories, Grove Medical Center is a very small system (500 people or fewer). Lake County has 266 active public water systems. Its population served is well below the county average of 2,442 people per system, and accounts for less than 0.1% of the 649,474 people reported by systems filed under the county. Across Illinois, the 3,872 active systems average 3,204 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Grove Medical Center 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. Illinois has 396 active non-transient non-community water systems, 10% of the state's 3,872 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,808 Illinois systems (73%) list groundwater as their primary source.
Who owns and regulates Grove Medical Center?
EPA lists Grove Medical Center as privately owned. The IL state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 193 of the 266 active systems in Lake County (73%) are also privately owned.
