Contaminated Sediments

Contaminated sediments in rivers, estuaries, and harbors has risen over the last decade to the forefront of today’s environmental challenges. Mutch Associates’ environmental engineers and hydrologists have been actively involved in some of the country’s largest Superfund sediment sites, including the Lower Passaic River in New Jersey, the Upper Columbia River, in Oregon and Washington State, and the Fox River, in Wisconsin. Our experience also includes a metals-contaminated sediment removal project on the upper Hudson River in Glens Falls, New York; investigation of sediments impacted by a plume of hexavalent chromium on the Hackensack River in Jersey City, New Jersey, and the active capping, pilot-scale, research project conducted by the Hazardous Substance Research Center, Southwest on the Anacostia River, in Washington, DC.
