Abstract

In southwestern Michigan aquifers are threatened by human activities. Parameter/factor weighting systems are used to rate aquifer vulnerability. Hydrogeologic factors affecting aquifer vulnerability were investigated in this study.

Well records, soil surveys, hydrogeologic reports, and partial chemical analyses were used to obtain data on the aquifers, soil types, glacial sediments, and types of contaminants. Data analysis included comparisons of means and medians, factor analysis, and Pearson and Spearman Correlation analysis.

The results indicate that the aquifers in Kalamazoo County are not protected. Depending on the type of glacial sediment, hydrogeologic factors that protect aquifers are clay thickness and the depth of the screen below the water table.
