Environmental effects of dredging. Long-term evaluation of plants and animals colonizing contaminated esturaine dredged material placed in an upland environment. Technical notes

OSTI ID:111798
Contaminated sediment was dredged from Black Rock Harbor, Connecticut, in October 1983 and placed in aquatic, upland, and wetland environments as part of the US Army Corps of Engineers/Environmental Protection Agency Field Verification Program (FVP), 1981-1986 (Peddicord 1988). Upland tests (plant and earthworm bioassays) were conducted on the sediment before dredging to evaluate potential contaminant mobility under the upland disposal alternative. Laboratory test results were subsequently field verified at the field test site at `Tongue Point,` Bridgeport, Connecticut. The results of the upland disposal portion of the FVP and the changes occurring since the completion of the FVP for the upland disposal environment are summarized herein. This technical note emphasizes the contaminant mobility of heavy metals. Contaminant mobility and the progressive development of the upland ecosystem at this site will be evaluated until September 1995.
