BATTELLE, AND Sea Engineering Inc. Field Study on Environmental Dredging Residuals: Ashtabula River; Volume I. Final Report . U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-10/126, 2010.
Impact/Purpose:
To summarize the evaluation of of sediment removal efficiency and the quantity and composition of the dredge residuals immediately following the completion of dredging. The results of the ecologica restoration segment of this project as well as out-year dredge residual studies will be addressed in a subsequent report.
Description:
A partnership was formed in 2006 between the National Risk Management Research Laboratory (NRMRL) and the National Exposure Research Laboratory (NERL) of the U.S. Environmental Protection Agency's (U.S. EPA's) Office of Research and Development (ORD) and U.S. EPA's Great Lakes National Program Office (GLNPO) as the remedy-of-choice for the Ashtabula River to remove sediments contaminated with polychorinated biphenyls (PCBs), the chemical-of-concern for this site. Under this partnership, a series of environmental measurements have been conducted on the Ashtabula River beginning in the fall of 2006 just prior to the initiaition of dredging on a 1-mile stretch of the river, during dredging in the summer of 2007, and immediately after dredging was completed in the fall of 2007 and cintinuing into post-dredge out years 2008, 2009, and 2010. Samples of sediment and overlying water were collected and analyzed before, during, and after dredging to evalute contaminated sediment removal efficiency. In addition, measurements were made to characterize the river's ecosystem before dredging and again during and after dredging to determine dredging impact on the river's ecosystem. This report summarizes the evalution of sediment removal efficiency and the quantity and composition of the dredge residuals immediately following the completion of dredging . Results of the ecological restoration segment of this project as well as out-year dredge residual studies will be addressed in a subsequent report.
