How does National Memorial Cemetery compare with other water systems in Maricopa County?
By EPA's size categories, National Memorial Cemetery is a very small system (500 people or fewer). Maricopa County has 217 active public water systems. Its population served is well below the county average of 20,368 people per system, and accounts for less than 0.1% of the 4,419,761 people reported by systems filed under the county. Across Arizona, the 1,769 active systems average 4,369 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so National Memorial Cemetery 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. Arizona has 232 active non-transient non-community water systems, 13% of the state's 1,769 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,612 Arizona systems (91%) list groundwater as their primary source.
Who owns and regulates National Memorial Cemetery?
EPA lists National Memorial Cemetery as owned by the federal government. The AZ state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 9 of the 217 active systems in Maricopa County (4.1%) are also owned by the federal government.
