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.

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.

Does Echo Valley School Ws have drinking water violations?
