Based on a recemly wmpleted study, the <br />source of elevated temperatures of WEM's fault waters u the elevated geothermal <br />gradient of the region. <br />The critical issue here is whether the elevated temperature of fault discharge water is <br />evidence of hydraulic communication between aster stored in the NW Panels sealed <br />sump and thermal water discharging from the Edward Mme portal spring. <br />PiW Paadt Sealed Sump <br />The NW Panels sealed sump has received appreciable quantities of water from both the <br />BFM and 14 SEHG faults, az well as a minor amount of cooler temperature operations <br />water and wlluvial inflows. Maximum recorded discharge temperatures ofBEM and la <br />SEHG fault waters were 89°F and 84°F, respectively. However, most measured <br />
