A multiphase compositional model is applied to reproduce in detail, the dense nonaqueous phase liquid (DNAPL) saturations and aqueous-phase plume migration in a highly characterized, heterogeneous glaciofluvial aquifer and two alternate methods, novel transition probability/Markov chain approach (TP/MC) and the conventional variogram analysis by ordinary kriging are used to reconstruct the same. It was found that the TP/MC modeling method is more precise, powerful and preferable than the ordinary kriging for the reconstruction of DNAPL saturation patterns and dissolved-phase contaminant plumes.

Introduction Contamination of ground water by dense nonaqueous phase liquids (DNAPLs) is an environmental problem of major concern throughout the industrialized world. These nonaqueous phase chemicals are more dense than [...]
