How does Temalpakh Farm compare with other water systems in California?
By EPA's size categories, Temalpakh Farm is a very small system (500 people or fewer). Across California, the 7,479 active systems average 5,706 people each.

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.
