Homes, apartments and mobile-home parks are served by these. Minnesota has 987 active community water systems, 15% of the state's 6,465 active systems. Purchased groundwater means the system buys groundwater from another public water system rather than drawing its own. 89 Minnesota systems (1.4%) list purchased groundwater as their primary source.
