Trace elements in the water, sediments, and fish of the Upper Mississippi River, Twin Cities Metropolitan Area:
Sampling Purpose: This study was conducted by the Metropolitan Council of Environmental Services (MCES; formerly Metropolitan Waste Control Commission). The sediment contaminant data are part of a larger monitoring effort by the MCES to obtain information on priority pollutants in surface waters of the Twin Cities (MN) area. Sediment samples were collected from the Minnesota, St. Croix, Vermillion, and Upper Mississippi (headwaters, and Pools 1-3) rivers. A total of 342 grab samples were analyzed for organic content, particle size, metals, organochlorines, polynuclear aromatic hydrocarbons, fungicides, herbicides, insecticides, miscellaneous industrial compounds, and polychlorinated biphenyls. In addition, fish tissue and water samples were analyzed for trace elements.
