Abstract: In this study, the relationship between the release characteristics of contaminants from soil and the biodegradability of the contaminants was evaluated. The soils used were from a large-scale field site. A batch rate of ...

Abstract: The long-term leaching of metals from concrete products made with spent abrasive media was investigated using a sequential extraction procedure employing both an acidic extraction fluid and seawater. By using seawater, ...

Abstract: Spent abrasive media from bridge repainting operations contain metals which may result in the media being classified as hazardous under the Environmental Protection Agency (EPA) Toxicity Characteristic (TC) criteria. The ...

Abstract: The hypothesis evaluated was that the extent to which a contaminated soil undergoes weathering prior to treatment affects the degree of chemical loss that occurs during bioremediation. The hypothesis was evaluated using ...

Abstract: Information about the loss and mobility of anthropogenic chemicals in soils over long periods of time—years to decades—was evaluated, with the purpose of providing a perspective on the extent to which such chemicals remain ...

Abstract: The objectives of this field study were to (1) remediate the contents of a pond containing petroleum refinery waste products, and 2) characterize the performance of the remediation effort in terms of changes in chemical ...
