Sediment Management

For a former wood treating site in Michigan, Mr. Palmerton managed an RI/FS, which included evaluation of groundwater impacts, recovery of NAPL and dissolved phase constituents, and evaluation of potential creosote impacts on sediments and fish. The operation of the collection system was shown to be effective in reducing impacts to sediments and fish. Fish consumption advisories were lifted in the adjacent river and remedial actions were undertaken for the removal of a small volume of sediments from a small tributary to the river. The Palmerton Group assisted with downstream evaluation of creosote impacts on sediment and negotiations with the Michigan Department of Environmental Quality for sediment removal.
