How does The High Lawn compare with other water systems in Essex County?
By EPA's size categories, The High Lawn is a very small system (500 people or fewer). Essex County has 24 active public water systems. Its population served is well below the county average of 28,269 people per system, and accounts for less than 0.1% of the 678,447 people reported by systems filed under the county. Across New Jersey, the 3,496 active systems average 2,750 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so The High Lawn 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. New Jersey has 637 active non-transient non-community water systems, 18% of the state's 3,496 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 3,313 New Jersey systems (95%) list groundwater as their primary source.
Who owns and regulates The High Lawn?
EPA lists The High Lawn as privately owned. The NJ 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 24 active systems in Essex County (17%) are also privately owned.
