Patent ID: 8210773

Claim:
A process for insitu treatment of at least one contaminant in a groundwater plume, the process comprises the steps of: installing a permeable reactive barrier in the flow path of the groundwater plume, wherein the installation of the permeable reactive barrier comprises the steps of: boring a first borehole with a portion longitudinally extending substantially parallel with an upper surface of the groundwater plume; filling the longitudinally extending portion of the first borehole with a reactive material comprising a solid reactant configured to react with the at least one contaminant in the groundwater plume to produce at least one product having less hazardous characteristics than the at least one contaminant; boring a second borehole with a portion substantially adjacent or overlapping the longitudinally extending portion of the first borehole; said first borehole and said second borehole having a common head; and filling the portion of the second borehole substantially adjacent the longitudinally extending portion of the first borehole with the reactive material; passing at least a portion of the groundwater plume having the at least one contaminant through a portion of the permeable reactive barrier; and reacting at least a portion of the at least one contaminant with a portion of the permeable reactive barrier to produce at least one product having less hazardous characteristics than the at least one contaminant.
