Surface-water-quality assessment of the Upper Illinois River Basin in Illinois, Indiana, and Wisconsin: geochemical data for fine-fraction streambed sediment from high- and low-order streams, 1987:
Sampling Purpose: Geochemistry of fine-fraction streambed sediments collected from the upper Illinois River basin was surveyed in the fall of 1987 as part of the U.S. Geological Survey National Water-Quality Assessment pilot projects. The survey included 567 samples; however, this data set contains only the higher-order streambed samples, totaling 225 samples. Composite grab samples were collected from the Illinois, Kankakee, Des Plaines, Fox, Calumet (Little and Grand), Du Page, and North Branch Chicago rivers, the Chicago Sanitary and Ship Canal, as well as, several higher-order creeks. The sediment samples were analyzed for carbon (total, organic, and carbonate) and 46 inorganic contaminants.
