State-of-the-art batch and column leach tests were conducted on anaerobic and aerobic New Bedford Harbor sediment. Batch testing included kinetic tests to determine the time required for dissolved contaminant concentrations to stabilize in batch tests, liquid-to-solids ratio tests to determine the appropriate liquid-to-solids ratio to use in batch tests, and sequential batch leach tess to obtain desorption isotherms and determine distribution coefficients. Column leach tests were conducted in divided-flow parameters designed to minimize wall effects. Desorption isotherms from sequential batch leach tests and elution curves from permeameter leach tests were used in an integrated approach to obtain information on contaminant release characteristics of New Bedford Harbor sediment.
