NAPL DISSOLUTION IN HETEROGENEOUS SYSTEMS : AN EXPERIMENTAL INVESTIGATION IN A SIMPLE HETEROGENEOUS SYSTEM

Description of experimental physical model consisting of a rectangular coarse sand lens surrounded by finer sand. Three different combinations of sand were used to determine the influence of the ratio of these sand grain sizes on napl distribution. Comparison of effluent concentration profiles for experiments with different initial napl saturations. Effect of distribution of heterogeneous packing with identical napl saturations.
