Abstract

Sand tank experiments have been used to study a surfactant-enhanced aquifer remediation (SEAR) process during which downward migration of dense nonaqueous phase liquid (DNAPL) has been observed in some of these experiments. Through numerical simulation of one particular sand tank experiment conducted at Sandia National Laboratories we show in this paper that this downward migration of DNAPL can be anticipated and controlled even in a very difficult geosystem environment. The results indicate that design simulations play a significant role in the design of either laboratory column experiments or field SEAR application and that surfactant flooding can be accomplished without loss of hydraulic control of DNAPL under typical alluvial aquifer/aquitard conditions and with only minor vertical mobilization within the aquifer (i.e.,
