Sediment samples from the New Bedford Harbor Superfund Site, New Bedford, MA, were stabilized/solidified using the following binders: portland cement, Portland cement with a proprietary additive, and a proprietary binder system. Comparison of contaminant masses released during sequential batch leaching of stabilized/solidified sediment and untreated sediment showed that stabilization/solidification reduced the leachability of some but not all metals investigated. The amounts of metal leached from stabilized/solidified sediment relative to the mass leached from untreated sediment were reduced by factors of 10 to 37, 1.2 to 2.6, 4.3 to 28, and 9.0 to 14 for cadmium, chromium, lead, and zinc, respectively. Copper and nickel, however, were mobilized by stabilization/solidification. The amounts of copper and nickel leached from stabilized/solidified sediment relative to the mass leached from untreated sediment were increased by factors of 20 to 23 and 9.6 to 17 for copper and nickel, respectively. Desorption isotherm analysis of sequential batch leach data showed that solidification/stabilization processing of this sediment altered the mechanisms controlling metal leaching.

Contaminated sediments from the Puget Sound Naval Shipyard were evaluated using solidification/ stabilization technologies to determine if the material could have beneficial uses. Varying ratios of four binders (Portland cement, kiln dust, lime/fly ash, and Portland cement/fly ash) were evaluated on the material to determine if soil-like properties could be obtained from the sediment. Physical, chemical, and contaminant leaching tests were performed on the untreated and treated material to evaluate the potential of the treated material for use as a daily landfill cover or other beneficial use. The major focus of the study was to determine if any of the binders could produce a material that had soil-like properties and that reduced the leaching of contaminants from the product so that regulatory guidelines could be met for the use of the material.

This book is one out six IAEG XIII Congress and AEG 61st Annual Meeting proceeding volumes, and deals with topics related to the geotechnical and environmental site characterization. The theme of the IAEG/AEG Meeting, held in San Francisco from September 17-21, 2018, is Engineering Geology for a Sustainable World. The meeting proceedings analyze the dynamic role of engineering geology in our changing world. The meeting topics and subject areas of the six volumes are: Slope Stability: Case Histories, Landslide Mapping, Emerging Technologies; Geotechnical and Environmental Site Characterization; Mining, Aggregates, Karst; Dams, Tunnels, Groundwater Resources, Climate Change; Geologic Hazards: Earthquakes, Land Subsidence, Coastal Hazards, and Emergency Response; and Advances in Engineering Geology: Education, Soil and Rock Properties, Modeling.
