This report summarizes analytical results obtained from water samples taken from 158 wells in southeastern Minnesota from October 1992 to January 1993. The sampling and analysis were part of a regional assessment of ground-water quality sponsored by the Southeast Minnesota Water Resources Board with funding from, and in cooperation with, the Minnesota Board of Soil and Water Resources (BWSR), the Minnesota Pollution Control Agency (MPCA), the Department of Geology at Winona State University (WSU), and the Minnesota Department of Agriculture (MDA). The purpose of the project was to acquire baseline data on ground-water quality of the major bedrock aquifers in this region. The primary water-bearing stratigraphic units that make up these aquifers, in order of elevation from highest to lowest, are the Cedar Valley Formation and the Galena Group; the St. Peter Sandstone; the Prairie du Chien Group; the Jordan Sandstone; and the Franconia, Ironton, and Galesville formations.
