Abstract : This report focuses on the non-linearities involved between tracer/non-aqueous phase liquid (NAPL) pairs and their subsequent effects on subsurface contaminant characterization. Two computer models were utilized; one model predicted the extent of the non-linear behavior between selected tracer/NAPL pairs. The second model utilized Freundlich and linear isotherm data fits to the non-linearities and predicted effluent response curves based on model conditions. Accepted methods for NAPL quantification in the subsurface were applied to the linear and non-linear effluent response curves and the differences were compared. The analyzed tracers include methanol, 2-methyl-2-hexanol, and 3-methyl-2 -hexanol. Trichloroethylene (TCE) served as the NAPL for the computer simulations. The simulation results show that NAPL saturation calculations are systematically underestimated when linear tracer partitioning is assumed. The NAPL saturation was underestimated by as much as forty percent for the specific interactions and model conditions used during this investigation. p4
