A model for the resistivity structure of LNAPL plumes and their environs in sandy sediments

Geophysical site characterization investigations at fuel spill sites have been generally guided by a working hypothesis which assumes that the light non-aqueous phase liquids (LNAPL) are a fully saturating phase of intrinsically very high electrical resistivity. Using observations from other related sciences, and contrary geophysical observations, a different model is developed which treats these spills as dynamic, changing systems dominated by...
