Water-quality assessment of part of the Upper Mississippi River basin, Minnesota and Wisconsin--trace elements in streambed sediment and fish livers, 1995-96:
Sampling Purpose: The U.S. Geological Survey's National Water-Quality Assessment Program collected streambed sediment samples to describe the occurrence and distribution of trace elements in the Upper Mississippi River Basin. In 1995 and 1996, the USGS collected sediment grab samples from 27 different sites on the UMR and tributaries. All samples were sieved and analyzed for trace metals, organic carbon, inorganic carbon, and total carbon.
