[vc_row][vc_column][vc_single_image image=”927″ img_size=”full” alignment=”center”][vc_column_text]Environmental dredging is defined as: “the removal of contaminated sediments from a water body for purposes of sediment remediation” (USACE). While there are several approaches to dealing with contaminated sediment, dredging is frequently the cleanup method of choice for projects under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as the “Superfund” program.

As no two projects are identical, the specific environmental limits set for a dredging project will vary. Several influencing factors include location, sediment composition, acting regulatory agencies, and environmental laws. To assist with this effort, the U.S. Army Corps of Engineers (USACE) has generated a comprehensive set of guidelines to evaluate environmental dredging as a solution for sediment remediation projects. While the EPA’s remediation guide addresses all possible steps and alternatives for dealing with contaminated sediment, the USACE’s guide focuses specifically on the dredging component.[/vc_column_text][/vc_column][/vc_row]
