Understanding the process of mass transfer from source zones of aquifers contaminated
with organic chemicals in the form of dense non-aqueous phase liquids (DNAPL) is of
importance in site management and remediation. A series of intermediate-scale tank
experiments was conducted to examine the influence of aquifer heterogeneity on DNAPL
mass transfer contributing to dissolved mass emission from source zone into groundwater
under natural flow before and after remediation. A Tetrachloroethylene (PCE) spill was …
