It is therefore important to develop reliable engineering models that can analyze in-situ treatment options prior to field testing, and can diagnose problems in the field. Approach Two similar models have been developed.
Convective transport occurs in the mobile phase, with mass transfer between the two compartments.
Soil columns are then used to adjust remaining parameters and measure the axial distribution of contaminant. This site is primarily contaminated with PAHs. Consequently, naphthalene and phenanthrene are currently being used as model pollutants. Numerical solutions of the mathematical models have been obtained, and parameter sensitivity studies conducted. Soil columns have been prepared, and bench-scale experiments initiated.
