How does Hopeton School compare with other water systems in Merced County?
By EPA's size categories, Hopeton School is a very small system (500 people or fewer). Merced County has 120 active public water systems. Its population served is well below the county average of 2,228 people per system, and accounts for less than 0.1% of the 267,324 people reported by systems filed under the county. Across California, the 7,479 active systems average 5,706 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Hopeton School 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. California has 1,466 active non-transient non-community water systems, 20% of the state's 7,479 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,179 California systems (83%) list groundwater as their primary source.
Who owns and regulates Hopeton School?
EPA lists Hopeton School as owned by a local government. The CA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 30 of the 120 active systems in Merced County (25%) are also owned by a local government.
