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. South Carolina has 82 active non-transient non-community water systems, 5.9% of the state's 1,392 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 933 South Carolina systems (67%) list groundwater as their primary source.
Who owns and regulates Us Silica (Sc3230005)?
