Abstract : Some of the sediment dredged from waterways is contaminated and must be tested to predict problems that might occur after disposal. Laboratory tests showed that as dredged material dried and oxidized, physicochemical changes occurred which changed the concentrations and form of contaminants found in surface runoff. The tests predicted that, initially, concentrations of suspended solids (SS) usually would be elevated and heavy metals would be poorly soluble and bound to the SS. As the material was dried and oxidized, SS concentrations in the runoff would decrease, and heavy metals such as copper, cadmium, zinc, nickel, and manganese would increase in solubility. Study results show that placement of Black Rock Harbor Conn. dredged material in an upland environment would allow physicochemical changes to occur that would significantly increase the solubility of Cd, Cu, Ni, Zn, and Mn. Filtered metal concentrations in surface runoff from dry, oxidized sediment would be statistically equal to unfiltered metal concentrations, indicating increased solubility of metals after dredged material was placed in an upland disposal site. Filtered concentrations of Cd, Cu, and Zn would also exceed the US EPA maximum criteria for the protection of aquatic life.
