Abstract

In 1990 the Illinois State Water Survey (ISWS) has started a multi-year effort, primarily observational in scope, aimed at assessing the likely magnitude and extent of agricultural chemical contamination in dug and bored wells in Illinois. Twenty-five rural, private wells each in Christian, Edgar, Sangamon counties have been sampled and tested for nitrate and a suite of twenty-three pesticides. Accordingly, the results suggest that agricultural chemical contamination of large diameter wells is a site specific problem rather than a regional one. Further, there is no correlation between elevated nitrate levels and the occurrence of pesticides; and dug wells are more likely than bored wells to have elevated nitrate levels or detectable pesticides.
