Much of Burnsville’s drinking water comes from 16 wells with depths ranging from 264-1030 feet. The wells take their water from the Jordan Aquifer, the Mt. Simon Aquifer, the Prairie Du Chien-Jordan Aquifer, and the Franconia-Mt. Simon Aquifer.
In 2010 when Burnsville began drawing surface water from local quarries, they received hundreds of calls from residents with the following complaints:
