Abstract

Dissolution rate depends on the molecular diffusion coefficient, the vertical dispersivity αv, the groundwater velocity v̄, the solubility, and the pool length. A value for αv for dissolution of trichloroethylene in a sand-filled physical model was found to be ~0.00023 m. This is consistent with vertical dispersivities reported from field experiments in heterogeneous media. With αv = 0.00023 m, at typical groundwater velocities, dissolution from CHC pools was found to be very slow; pools containing a few hundred to a few thousand kilograms of CHC solvent will persist for decades to centuries. Pool lifetimes can be shortened by increasing the groundwater velocity through pumping. However, lifetimes will not usually be reduced by more than a factor of 5. -from Authors
