The U.S. Geological Survey, in cooperation with the the Indiana Department of Environmental Management, computerized the available pesticide and pesticide metabolite data for Indiana ground water. The data had been collected during 6 statewide surveys and 15 localized studies by the Indiana Department of Environmental Management, the Indiana Department of Natural Resources, the U.S. Environmental Protection Agency, and the U.S. Geological Survey. Ground-water samples were collected from 521 sites in 81 of 92 Indiana counties, including 179 public supply wells, 304 domestic supply wells, 36 observation wells, and 2 springs; 41 percent of all sites were sampled more than once. Thirty wells were sampled in response to alleged ground-water contamination with pesticides. Results of analyses of 725 samples were summarized for the period December 1985 through April 1991.
