![]() ![]() ![]() Water (or other liquid) that separates from the sediment particles,.Sediment particles and entrained porewater,.Other Technology NamesĮnvironmental dredging or excavation of contaminated sediment produces three categories of materials that may require processing prior to disposal or reuse. Treatment may include dewatering followed by separation, solidification, thermal desorption or incineration, and adding amendments to create various products for beneficial reuse. The type and degree of treatment are based on the types of contaminants in the sediment, regulatory requirements, remedial goals, costs, and other site-specific considerations. Processing of dredged sediment generally includes dewatering followed by one or more types of treatment prior to disposal or reuse. Unlike navigational dredging projects where the sediment is suitable for unrestricted placement within public water bodies or on upland property, dredged material produced during environmental dredging generally requires significant processing prior to disposal or reuse due to the presence of contaminants within the material. Materials removed by dredging of sediments require transport and may require processing prior to placement in a disposal facility or beneficial reuse site.
