Title from cover. Includes bibliographic references. "Prior to full-scale sediment treatment, it is necessary to conduct small-scale treatment evaluations. In situ assessments have some advantages over laboratory treatments with respect to maintaining relevant temperature, redox, and light conditions. Direct injection with divers allows for in situ incubations but the lack of control over the treatment produces variance that makes optimization of the treatment difficult. To have the advantages of both in situ and laboratory approaches, we collected box cores via a diver, mixed in the reagents at the surface and put the samples back into the hole in the sediments where they came from. Evaluations of equipment for full-scale remediation are also required to optimize the treatment process"--Abstract. Includes abstract in French. gccst Sediments gccst Water management Canada.
