How does Oregon Grille compare with other water systems in Baltimore County?
By EPA's size categories, Oregon Grille is a very small system (500 people or fewer). Baltimore County has 272 active public water systems. Its population served is well below the county average of 168 people per system, and accounts for less than 0.1% of the 45,805 people reported by systems filed under the county. Across Maryland, the 2,992 active systems average 1,947 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Oregon Grille 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. Maryland has 491 active non-transient non-community water systems, 16% of the state's 2,992 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,870 Maryland systems (96%) list groundwater as their primary source.
Who owns and regulates Oregon Grille?
EPA lists Oregon Grille as privately owned. The MD state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 221 of the 272 active systems in Baltimore County (81%) are also privately owned.
