Consequently, the focus of this paper will be upon the work of the sediment subcommittee of the International Joint Commission in the identification of appropriate remedial technologies for con0t this material remains a problem will be upon the work of laminated sediment BACKGROUND The government of Canada and the United States signed the Boundary Waters Treaty on January 11, 1909, which outlined the rights of each country in the use of Great Lakes waters. In the 1960s, growing public concern about the quality of water in the lower Great Lakes resulted in 280

At that time the committee's objectives were to develop guidelines and criteria for dredging activities, maintain a register of dredging projects, exchange information on technology and research, and identify criteria for the classification of polluted sediments in areas that were continually dredged. In 1986, the sediment subcommittee was created when it became clear that one of the key elements in the development of remedial action plans for areas of concern was the need to refine existing assessment techniques for polluted sediment as well as identify implementable remedial options for polluted sediment.

? The options currently being evaluated are open-water disposal, capping in place, confined disposal, lake filling, agricultural land spreading, strip mine reclamation, decontamination treatment, and solidification.

This is a very cursory identification and categorization of options. For a more detailed discussion of remedial technologies the reader is asked to refer to Technologies for the Remediation of Contaminated Sediments in the Great Lakes; Report of the Sediment Subcommittee and its Remedial Options Work Group to the Water Quality Board of the International Joint Commission, July 1988.

Some Limitations and Remedial Options Requiring More Testing Hydraulic control navigation relocation: suitable for docking slips/shipping channels; minimizes resuspension of contaminants during shipping activities. Reclamation of strip mines and quarries: proximity of site is the major constraint, groundwater impact must be considered.

Equally important as mapping is the formulation of a comprehensive sediment collection program involving streams and suspended sediments, bottom sediments, sediment resuspension and transport, sediment chemistry, nutrients, organics and sediment toxicity and bioavailability.
