Abstract:
Free-phase DNAPL recovery operations are becoming increasingly prevalent at
creosote-contaminated aquifer sites. This paper illustrates the potential of both
classical and innovative recovery methods. The UTCHEM multiphase flow and transport
numerical simulator was used to predict the migration of creosote DNAPL during a
hypothetical spill event, during a long-term redistribution after the spill, and
for a variety of subsequent free-phase DNAPL recovery operations. The physical
parameters used for the DNAPL and the aquifer in the model are estimates for a
specific creosote DNAPL site. Other simulations were also conducted using physical
parameters that are typical of trichloroethene (TCE) DNAPL. Dramatic differences in
DNAPL migration were observed between these simulations.
