This technical memorandum was prepared to summarize results of drilling, construction, equipping, and testing at hydrologic test well DHRES-06. The well was installed to characterize hydrogeologic conditions in the deep groundwater system south of the South Boundary Fault and to provide a monitoring point for the deep groundwater system during dewatering of existing mine workings. Monitoring data obtained from DHRES-06 will be incorporated into the RCM hydrologic monitoring program.
