The primary objectives of the project were to perform a review of existing in-situ techniques of sediment erosion potential evaluation in contaminated “Superfund” sites in the United States and those from Europe and Japan and the applicability of soft soils in-situ stabilization and solidification techniques in marine environments. The project also sought to determine design parameters for field application of in-situ methods for stabilization of contaminated sediments and make a recommendation on the appropriate types of reagents to be considered for in-situ solidification of marine sediments. (Issues such as binder compatibility and chemical stabilization potential will be considered in the selection of these binders.)Finally, the project involved a review and evaluation of experimental design program for the ex-situ testing phase of sediments amended with the selected binders.

Soilteknik, Inc., provided consultation and expert advice on the design of experiments to be conducted by the CAIT team on the subsequent “Evaluation of Erosion Potential of Estuarine Sediments in NY/NJ Harbor using an Advanced Ex-Situ Erosion Testing Method” project. The main focus of the consulting assignment was to evaluate the potential of in-situ stabilization on the remediation of contaminated sediments. Such an understanding is required for the experimental design and selection of appropriate binder agents for future testing and evaluation in the ex-situ system.
