Book Description
The purpose of this project was to evaluate the potential effects of leachates from upland dredged material disposal areas on groundwater quality. A laboratory simulation was developed using Plexiglas lysimeter columns filled with two types of interfacing soils and dredged materials obtained from five actual upland disposal sites. Various leaching solutions were passed through both a dredged material and an interfacing soil placed in tandem in a Plexiglas lysimeter. Several types of water samples were studied. The study showed that the migration of constituents in dredged material/interfacing soil systems is complex; no single mechanism can account for the various trends and levels of migration. The major mechanisms that appeared to affect the migration of constituents from dredged material were solubilization, adsorption, complexation, redox reactions, ion exchange, and dilution.
