Description:
Dredged material can be a valuable resource for environmental ehnacement projects such as restoring or establishing new wetlands for beach restoration and stabilization, and fill material for flood rotection and new developments Few studies have addressed both the ecological and public health aspects of the reuse of dredged sediments. This can be an oversight, as sediment can contain deleterious amounts of toxic metals, which would require reduction propr to application or use, to prevent leaching into the environment. The present study evaluates the performance of an amendment admixture to alter trace metal speciation and thereby reduce mobility and improve the quality of natural sediment in an upland reutilization scenario.
