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 a trichloroethene (TCE) DNAPL. Dramatic differences in DNAPL migration were observed between these simulations.
