This technical memorandum was prepared to summarize results of drilling, construction, equipping, and testing at hydrologic test wells HRES-10 and HRES-11. The wells were installed to characterize hydrogeologic conditions in the Apache Leap Tuff (Tal) in the southeast extent of the Tal outcrop area near Mineral Creek. Monitoring data obtained from HRES-10 and HRES-11 will be incorporated into the RCM hydrologic monitoring program.
