Results of Drilling, Construction, Equipping, and Testing at Hydrologic Test Well HRES-16, HRES-17, and HRES-18

This technical memorandum has been prepared to summarize results of drilling, construction, and testing at hydrologic test wells HRES-16, HRES-17, and HRES-18. The wells were installed to characterize hydrogeologic conditions in the Apache Leap Tuff (ALT) on the east side of Devils Canyon near the JI Ranch Fault. HRES- 16 is a larger diameter well (nominal 8-inch) that was completed to provide a location for longterm aquifer testing in the ALT aquifer. Monitoring data obtained from HRES-16, HRES-17, and HRES-18 have been incorporated into the RCM hydrologic monitoring program.
