If aggressive laboratory NAPL mobility tests force NAPL to move out of test samples, that creates an opportunity to quantify key parameters for NAPL mobility assessment. Fundamental parameters governing fluid flow through porous media are hydraulic conductivity, Darcy flux, and average lineal seepage velocity. They are commonly estimated to evaluate groundwater flow. However, they also apply to non-aqueous phase liquid (NAPL) and can be estimated based on field NAPL recovery data or laboratory NAPL mobility test results using soil or sediment cores containing NAPL...read more.
