How does Tseiiahi (Standing Rock) Community School Bia compare with other water systems in New Mexico?
By EPA's size categories, Tseiiahi (Standing Rock) Community School Bia is a very small system (500 people or fewer). 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 Tseiiahi (Standing Rock) Community School Bia 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. New Mexico has 151 active non-transient non-community water systems, 13% of the state's 1,165 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 62 New Mexico systems (5.3%) list purchased groundwater as their primary source.
Who owns and regulates Tseiiahi (Standing Rock) Community School Bia?
