Results of Drilling, Construction, Equipping, and Testing at Hydrologic Test Well DHRES-09

This technical memorandum was prepared to summarize results of drilling, construction, and testing at hydrologic test well DHRES-09. The well was installed to characterize hydrogeologic conditions in the deep groundwater system west of the Concentrator Fault and east of the Main Fault, and to provide a monitoring point for the deep groundwater system during on-going dewatering operations. Monitoring data obtained from DHRES-09 have been incorporated into the RCM hydrologic monitoring program.
