Distribution of potentially toxic metals in bed sediments, crayfish, and fish of the Upper Wisconsin River:
Sampling Purpose: In 1981, samples from bed sediments, fish, and crayfish were collected from reservoirs in the Upper Wisconsin River. Several pulp and paper mills discharge waste into the Wisconsin River, which has a history of elevated mercury levels, in addition to other metals. Three to six sediment cores (194 total samples) were collected from five different study areas on the river. The sediment cores were dated by Cesium -137 decay. All samples were analyzed for particle size, organic carbon (%), and metals. This study did not contain sample coordinate information; however, detailed sampling maps were provided, and coordinate information was approximated in ArcView.
