Upper carbonate aquifer

Map showing Upper carbonate aquifer

Detailed Description

The upper carbonate aquifer is a very productive aquifer only in southeastern Minnesota. Numerous solution-enlarged rock openings have made the rocks extremely porous, especially where glacial deposits are thin or missing. In the Iowa portion of the aquifer, dissolution has been inhibited, so little secondary permeability has developed.
