Abstract

This disclosure relates to systems for remediation of groundwater in geological formations and methods of groundwater remediation in geological formations. The system can include a wellbore within a geological formation comprising an aquifer, a casing, inner tubing, a water passage, outer tubing comprising a plurality of diffusion membranes, and a formation conduit in fluid communication with the aquifer. The method may include forming a dissolved remediation gas solution within a wellbore by: passing remediation gas through an inner tubing, passing an aqueous solution into the wellbore through a water passage and an outer tubing comprising a plurality of diffusion membranes, and passing the remediation gas through the diffusion membranes to be mixed with the aqueous solution in the outer tubing to produce the dissolved remediation gas solution; and transporting at least a portion of the dissolved remediation gas solution to an aquifer within the geological formation.
