Water Quality in Carbonate Aquifers in the United States

Land cover varied among aquifers in this study

All but two of the aquifers are dominated by a mixture of agricultural and forested land use. The Biscayne aquifer is largely overlain by urban areas, and the Basin and Range aquifer is overlain largely by shrub land. The Mississippian, Silurian-Devonian/Upper carbonate, Ozark Plateaus, Piedmont, Prairie du Chien, and Valley and Ridge aquifers/aquifer systems are dominated by agricultural land use. The illustration shown is based upon figure 3 of SIR 2008-5240.
