This technical memorandum was prepared to document results and analysis of a 90-day aquifer test conducted by RCM at well HRES-20 completed in the Apache Leap Tuff (ALT) aquifer.

This technical memorandum was prepared to document results and analysis of a 60-day pumping test conducted at hydrologic test well HRES-07.

This technical memorandum was prepared to provide an interim summary of data collected at wells DHRES-01 and DHRES-02. Deep hydrogeologic test wells DHRES-01 and DHRES-02 were drilled and constructed during the period May 2 to September 10, 2008. In order to measure hydraulic heads at specific elevations in the Apache Leap Tuff (Tal) and Whitetail Conglomerate (Tw), vibrating-wire pressure transducers were grouted in the annulus between the borehole wall and conductor casing at wells DHRES-01 and DHRES-02.

This technical memorandum was prepared to summarize the results of a long-term aquifer test conducted at Resolution Project hydrologic characterization well HRES-4. Well HRES-4 is completed in the Apache Leap Tuff aquifer near Oak Flat, in the upper Queen Creek drainage basin of eastern Pinal County, Arizona.

The final EIS and draft Record of Decision (ROD) presently are scheduled to be published in the Federal Register sometime in winter 2020.
