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. Louisiana has 125 active non-transient non-community water systems, 11% of the state's 1,121 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 966 Louisiana systems (86%) list groundwater as their primary source.
