摘要：

Biodegradation of contaminant plumes is limited by electron acceptor/donor availability and inhibition of bacterial activity due to the presence of toxic contaminant concentrations. Both of these limitations may be overcome, under certain conditions, through the use of hydraulic manipulation (HM), an in situ groundwater restoration concept to enhance contaminant dilution and mixing of electron acceptors with electron donors within the aquifer. MT3D99 and RT3D reactive transport modelling was undertaken to assess the feasibility of HM as a remediation scheme and to find the most effective well configurations for a variety of conditions. HM was found to be most effective for medium-scale biodegradable plumes, with relatively low contaminant concentrations, in heterogeneous porous media. Greatest contaminant mass loss was predicted using complex or adaptive pumping schemes involving repeated, alternating injection of clean groundwater with electron acceptors within the plume, combined with external pumping and natural groundwater flow to move the plume as required.
