Sustainable Waste Management through the Beneficial Use of Dredge Materials in Partnership with the City of Savannah

The suitability of dredge material as a landfill cover material varies, depending on the physical properties of the sediment being considered (NJDEP, 2007). For example, very fine-grained material is generally unacceptable for use as landfill cover due to poor hydraulic conductivity, susceptibility to erosion, and formation of dust. Poor drainage characteristics result in formation of leachate seeps on landfill side slopes. Salt content and pH must be appropriate to support growth of the desired vegetation species for use as a final closure. The objective is to assess feasibility of dredge material for applications of interest to Georgia Department of Transportation (GDOT) and the City of Savannah.
