How does Montessa Park compare with other water systems in Bernalillo County?
By EPA's size categories, Montessa Park is a very small system (500 people or fewer). Bernalillo County has 82 active public water systems. Its population served is well below the county average of 7,846 people per system, and accounts for less than 0.1% of the 643,386 people reported by systems filed under the county. Across New Mexico, the 1,165 active systems average 1,885 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Montessa Park 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. New Mexico has 151 active non-transient non-community water systems, 13% of the state's 1,165 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,009 New Mexico systems (87%) list groundwater as their primary source.
Who owns and regulates Montessa Park?
EPA lists Montessa Park as owned by a local government. The NM state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 19 of the 82 active systems in Bernalillo County (23%) are also owned by a local government.
