J.C. Olimpio 1982 The U.S. Geological Survey is studying the geologic, hydrologic, and geochemical properties of the glacial drift and underlying bedrock at a low-level radioactive-waste burial site in the Palos Forest Preserve, 22 kilometers southwest of Chicago. Data collected from the 33 test wells drilled into the drift plus data from 4 wells drilled into the underlying dolomite bedrock are presented. Data include maps showing the location of the test wells, a general description of the drift, well-construction information, and lithologic descriptions of cores from the wells finished in the drift. application/pdf 10.3133/ofr82692 en U.S. Geological Survey, Data for wells at the low-level radioactive-waste burial site in the Palos Forest Preserve, Illinois reports
