Compatibility of bentonite and DNAPLs
The compatibility of dense nonaqueous phase liquids (DNAPLs), trichloroethylene (TCE), methylene chloride (MC), and creosote with commercially available sodium bentonite pellets was evaluated using stainless steel, double ring, falling head permeameters. The hydraulic conductivity (K) of the bentonite clay was measured under three experimental conditions: (1) water soluble constituents of the DNAPLs were used to hydrate and permeate the bentonite; (2) bentonite pellets were submersed in DNAPL prior to hydration and permeation with water; and (3) DNAPLs were pooled on water-hydrated bentonite. Further, the effect of hydraulic head on water-hydrated bentonite permeated with TCE and the effects of TCE exposure time to mixtures of bentonite grout and sand were measured.
