Chemical analysis of dredge sediment collected in the Marseilles Canal and below Dresden Island Lock:
Sampling Purpose: The U.S. Army Corps of Engineers (ACOE) routinely collects samples before dredging, and analyzes the samples for contaminants to assess possible problems associated with the dredging process and the placement of dredged material. In 1988 and 1995, the Rock Island District of the ACOE collected core samples from the Illinois River (river miles 245.2-246.9 and 270.9-271.0), and analyzed them for volatile matter, particle size, and metals. In addition, one sample was analyzed for several organic contaminants including organochlorines, fungicides, and miscellaneous industrial compounds. Sample coordinate information was not provided with this study; however, coordinates were approximated in ArcView using detailed maps and site descriptions.
