Sustainable Waste Management through the Beneficial Use of Dredge Materials in Partnership with the City of Savannah
The Savannah Harbor’s dredged material containment areas are spread across 7,000 acres along the South Carolina side of the lower Savannah River. A demonstration project to determine whether dredged material could feasibly serve as landfill cover was undertaken. As such, the long-term project viability, including post-construction geotechnical and environmental monitoring was conducted. The results from the geotechnical tests indicate that the dredged materials were classified as poorly graded sands according to the Unified Soil Classification System. The soils contained a little amount of silt and clay that passed through a #200 sieve and exhibited the typical fine and coarse sand’s permeability, which made the dredged materials suitable for landfill. Water quality monitoring over the course of six months found that the limits stipulated by the Environmental Protection Division under Section 20 of the Clean Water Act “Monitoring of Surface Water and Underdrain Systems at Solid Waste Facilities” were not exceeded, further indicating material suitability. An economic analysis revealed that cost savings for the landfill was possible, but highly dependent on variables including distance to site, labor, and diesel cost.
