![]() ![]() All associated risks must be carefully considered during the design phase to develop a successful plan for mitigating risks and reversing short-term disturbances. However, dredging is a highly invasive remediation option, and can have long-term negative impacts on aquatic habitats and benthic species if appropriate control measures and best management practices are not used (ITRC, 2014 Manap and Voulvoulis, 2014). In addition, fewer limitations are placed on future site uses, as compared to in situ remediation where contaminated sediments remain in place. The key advantages of dredging over other remediation options are that dredging typically requires shorter timelines to complete and results in greater certainty about the long-term effectiveness of remediation activities. ![]() Dredging, followed by treatment and disposal of the contaminated material, has become one of the most commonly implemented methods for sediment remediation in North America. ![]() The terms dredging, environmental dredging, or underwater excavation refer to the removal of contaminated sediments from a water body for purposes of sediment remediation.
