A simulation of a buried contamination source consisting of barrels containing Dense Non-Aqueous Phase Liquids (DNAPL) and Light Non-Aqueous Phase Liquids (LNAPL). The simulation is a pseudo-physical simulation. Contaminant particles follow either gradients provided by the groundwater surface (LNAPL) or gravity and groundwater gradients (DNAPL). DNAPL particles on contact with an Aquitard tend to follow the slope of the aquitard and may move contrary to the groundwater flow direction. The simulation does not fully conceptualize dispersion or other limiting forces to contaminant transfer. The simulation was prepared by Eric Xanderson (Eric@lorefolk.com) and constructed primarily in Blender (http://Blender.org).
