Abstract:

The interactions between solutes found in leachates from uncontrolled landfills and components of a soil-bentonite SB slurry wall are capable of causing swelling or shrinking slurry wall. The effect of solutes in contaminated ground water from the Ninth Avenue Superfound Site in Gary, IN, on the hydraulic conductivity of two SB slurry wall backfill mixtures was evaluated using rigid- wall permeameters. Ground-water samples taken from three observation wells at the Ninth Avenue site contained solutes that could cause increases in the hydraulic conductivity of an SB slurry wall. One ground-water sampled contained salt concentrations as high as 20,000 mgl.
