Hydrologic Test Wells HRES-19, HRES-20, QV-5 Completion Report
At HRES-19 and HRES-20, the primary target drilling depth was the contact between the Tertiary Apache Leap Tuff and the underlying White Tail Conglomerate. During drilling operations, data was collected to better characterize the hydrogeologic conditions within the Apache Leap Tuff. The target depth was reached at HRES-19, although the depth to the White Tail Conglomerate was shallower than expected. The White Tail Conglomerate was not reached at HRES-20 due to technical issues encountered while drilling. The hydrologic test wells will eventually be used to further evaluate regional aquifer characteristics through long-term pumping tests and water quality sampling. At QV-5, the main objective was to install and test a well that would provide a reliable supply of fresh water while collecting pertinent lithologic and hydrogeologic data from the site.
