Variations of Sulfur Isotope Ratios in Samples of Water and Air Near Chicago Ben D. Holt,l Antoinette G . Engelkemeir, and Adolph Venters Chemistry Division, Argonne National Laboratory, Argonne, IL 60439
rn Sulfur-34 variations were measured in surface waters, municipal wells, sewage treatment plants, rain, and air in a suburban area west of Chicago. The study was centered on Salt Creek which, with neighboring streams, apparently characterizes the glacial-deposit area as being depleted in 34S, with respect to meteoritic troilite. Three apparent perturbants of 34Senrichment in the small stream were rain, earth-surface disturbances, and effluents from sewage treatment plants. Deep municipal wells (>350 meters) were strongly enriched in 34Sand shallow municipal wells (
