Patent ID: 8366350

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 with a boring device, the permeable reactive barrier being configured and disposed to intercept the migration of at least one groundwater contaminant in the groundwater plume, the installation of the permeable reactive barrier comprising the steps of: boring a first borehole with a first longitudinally extending portion in the groundwater; 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; retracting the boring device from the longitudinally extending portion of the first borehole and into the first borehole, without removing the boring device from the ground; boring a second longitudinally extending portion in the groundwater; and filling the longitudinally extending portion of the second borehole with the 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; passing at least a portion of 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.
