Patent ID: 8596351

Claim:
A method for in situ remediation, comprising: identifying an aquifer to be remediated; determining site qualities of the aquifer, including average hydraulic conductivity and the rate and direction of flow of contaminated groundwater through the aquifer; drilling a plurality of boreholes from the ground surface into the aquifer; forming a plurality of wells by inserting a plurality of well pipes into the boreholes, wherein at least one part of one well pipe is disposed substantially horizontal to contaminated groundwater flow with respect to vertical and parallel to contaminated groundwater flow when viewed from the ground surface, wherein further at least one well pipe comprises a first section and a second section, wherein the first section comprises a first filter portion and a solid wall portion which is substantially permeable to groundwater flow, wherein the first filter portion is situated up-gradient of the flow of the contaminated groundwater; and the second section comprises a second filter portion and a solid wall portion which is substantially permeable to groundwater flow, wherein the second filter portion is situated down-gradient of the flow of the contaminated groundwater; and thereafter emplacing reactive media into the interior of the well pipes, wherein the hydraulic conductivity of the reactive media situated in the interior of the well pipes is greater than the average hydraulic conductivity of the aquifer, wherein a portion of the flowing contaminated groundwater funnels into the well pipes through the first filter of the first section, and exits through the second filter of the second section, and wherein further the contaminated groundwater is treated by the reactive media as it passes through the interior of the well pipes.
