How does Liberty Marina compare with other water systems in Anne Arundel County?

By EPA's size categories, Liberty Marina is a very small system (500 people or fewer). Anne Arundel County has 405 active public water systems. Its population served is well below the county average of 1,397 people per system, and accounts for less than 0.1% of the 565,834 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 Liberty Marina 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 Liberty Marina?

EPA lists Liberty Marina 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. 361 of the 405 active systems in Anne Arundel County (89%) are also privately owned.
