Title: Evaluation of Chemical and Physical Characteristics of Water Treatment Residuals Before and After a Freeze-Thaw Cycle
Author: Murphy, Eileen A.; Dempsey, Brian; DeWolfe, James; Lunetta, Mark; Elias, Steven
Abstract: The effects of natural freeze/thawing on the chemical and physical characteristics of eight NJ water treatment residuals were investigated in relation to trace metal leaching. Field and laboratory studies indicate that leaching of metals from residuals which have undergone a freeze/thaw cycle is considerably less than raw residuals. Furthermore, freeze-thawed residuals mixed with NJ soils leached metals less than raw residuals mixed with soils. The freeze/thaw residuals-soil mixtures, in most cases, exhibited leaching characteristics similar to those of the soils alone.
