Subsurface structural control of DNAPL migration
- ERM-Northeast, Syracuse, NY (United States)
The migration of dense nonaqueous phase liquid (DNAPL) in ground water is driven by gravity, and is controlled by subsurface stratigraphy and relief on the top of the underlying aquitard. Research models, conducted at the bench scale, have proposed that DNAPL can migrate against ground-water flow directions; however, it is rarely demonstrated at actual release sites. In this paper, the author presents the results of extensive soil and ground-water sampling at two inactive hazardous waste sites in New York state that demonstrate subsurface structural control of solvent migration. In both cases, initial migration routes were counter to ground-water flow directions, and migration was controlled by relief on the underlying aquitard.
