This paper provides a brief summary of the state of metal contaminated sediment remediation.Currently the most commonly used method to remediated metal contaminated sediments is environmental dredging(85%),followed by monitor natural recovery MNR)(6%)and capping(6%).Combinations of technologies are emphasized in the management and remediation of contaminated sediments.Logical progression should start with dredging of hot spots and source control.After source control,the most appropriate action is often monitored natural recovery(MNR),but if more than MNR is required,additional engineering such as active capping can be incrementally added.Consideration of the state-of-the-art suggests that there is a need for new remediation technologies or modification of existing ones; e.g.,capping technologies that can sequester sediment contaminants and create a reliable,stable,and long-lasting cap in a range of aquatic environments.Current technologies typically produce caps with limited physical stability that are suited primarily for low-energy,depositional aquatic environments.However,depositional environments can become erosive as a result of unpredictable natural events such as floods and storms and anthropogenic actions such as boating and construction activities.Therefore,future research should emphasize the development of caps that have the capacity to both stabilize contaminants and resist the physical disturbances that are likely to occur over the required life-time of the cap.Also,the application of in-situ remediation methods such as reactive amendment mats,mixing of amendments in the sediment,and mixing or layering of amendments within sand caps should be emphasized when selecting remedial technologies for contaminated sediments,and more field evaluations of these methods are needed.
