1992 sediment quality report for Mark Twain National Wildlife Refuge Illinois, Iowa and Missouri:
Sampling Purpose: In 1992, the U.S. Fish and Wildlife Service (FWS) collected sediment samples from backwater areas in the Mark Twain National Wildlife Refuge along the Upper Mississippi River (UMR). In addition to assessing benthic fauna, sediment sampling was conducted under the Sediment Quality Triad approach, which determines analytical chemistry and toxicity of sediments in Microtox assay. Sediment grab samples were collected in Pools 17-19, 21, and 23 of the UMR, and were analyzed for organic carbon, acid-volatile sulfide, particle size, water content, and metals.
