This guide describes contaminated sediment treatment scenarios (with variants) available to project promoters: everything from no action to partial or total removal of sediment contaminants, depending on the decontamination level required by current criteria. The strengths and limitations of each scenario are outlined, and scenario evaluation and selection criteria are proposed. Pretreatment technologies are described, and each's stage of development, strengths and limitations are indicated. Soil and sediment treatment technologies tested in different parts of the world or under demonstration for sediment remediation are described. For each type of technology, the following information is given: basic principle, methods or processes available, application, strengths and limitations, processes demonstrated on sediment processes under demonstration and processes recommended for contaminated sediment cleanup projects. Given the amount of contaminated water generated by the handling and treatment of sediment, the guide also describes technologies demonstrated or under demonstration for effluent or leachate treatment.
