In situ recovery (ISR) uranium mining is a technique in which uranium is extracted by a series of injection and recovery wells developed in a permeable sandstone host rock. Chemical constituents (lixiviants) are added to groundwater injection wells to mobilize uranium into groundwater. Before mining, baseline water quality is measured by sampling groundwater from the aquifer intended to be mined and over and underlying units over a geographic area that reflects the proposed mine location. After mining, groundwater is restored using a variety of techniques intended to return groundwater quality to as close to baseline as practicable. After groundwater has been restored, groundwater quality is monitored to determine...
