Abstract:

The purpose of this paper is to understand in part the dynamic impact of surfactants on hydraulic conductivity for designing enhanced pump and treat operations. This paper has two aims: to quantify and model the decreasing hydraulic conductivity of a natural sand due to the transport and deposition of clay, and to investigate the change in particle size distribution of clay and sand in solutions of varying surfactant concentrations.
