Abstract:
The US Army Corps of Engineers is responsible for maintaining our Nation’s navigable waterways and dredges over 300 M cu yd of sediment each year.
Sediments not meeting regulatory requirements for aquatic disposal are placed into confined disposal facilities (CDF). Existing CDFs are filling rapidly and
construction of new ones to meet the continuing dredging mission is limited by declining space around our ports and harbors and increasing cost of construction.
Although most CDFs contain clean to only marginally contaminated sediments that are suitable as a soil resource, removal of these sediments for beneficial uses is a fraction of what is needed to restore capacity of existing CDFs for future dredging needs. Opportunities exist for a number of uses of dredged sediments as a soil material that can provide cost savings to local interests. Current studies are
evaluating the use of dredged sediment for various soil products in the landscaping and nursery industries as well as remedial cover for mine land restoration. Testing and evaluation is also being conducted to develop protocols for determining
suitability for various uses. Examples of beneficial uses including nursery container media, topsoil for landscaping and cover for mine land reclamation will be
presented.
