Permit applications may be received which propose to place hazardous waste land disposal facilities in a saturated zone of low permeability (low-K) soils. This report addresses only movement of the leachate after release from the facility and does not consider those factors relating to the containment afforded by the facility proper. Discussions include: (1) soil characteristics and the influence soil-forming mechanisms have on the types of heterogeneities and anisotropies to be expected in low-K soils; (2) the roles played by the tension-saturated zone, anisotropies, and heterogeneities in subsurface leachate movement; (3) the advantages and disadvantages of various available computer models to simulate leachate movement in the staturated, low-K anisotropic, and heterogeneous cases.
