DENNIS R. MCGRANE <br />EDUCATION <br />B.A., 1985, Geology, Dartmouth College <br />REGISTRATION <br />Professional Engineer (Civil), Colorado (#33232) <br />Professional Geologist, Wyoming (PG-422) <br />Registered Geologist, Arizona (#26038) <br />A. I. P. G. Certified Professional Geologist (#9b21) <br />EXPERIENCE <br />Leonard Rice Engineers, Inc. <br />2004-Present -Project Manager <br />2000-2001 -Project Manager <br />1993-1999 -Project Hydrogeologist <br />1990-1992 -Staff Hydrogeologist <br />1989 -Assistant Geologist <br />Responsible for project management and technical performance on projects involving nearly <br />every aspect of evaluating hydrogeologic systems. <br />Evaluating the feasibility of artificial recharge projects in Colorado and Arizona. <br />Specialize in computer modeling of surface water and ground water interactions to evaluate <br />ground water development and water rights issues. Routinely interpret existing geologic and <br />geophysical logs, geologic and hydrologic maps and water quality data. Field activities include <br />geologic mapping, well installation, and aquifer testing. Significant projects include: <br />Evaluation of the aquifer life of the Coconino Aquifer (Arizona) as a 5,000 gpm industrial water <br />source using the U.S.G.S. MODFLOW computer model. Results were used to deepen existing <br />wells and forecast regional ground water impacts. <br />Utilized MODFLOW to evaluate stream depletions caused by ground water pumping for a lazge <br />hydroelectric facility in Arizona. <br />Evaluation of the South Platte alluvial aquifer in the vicinity of Brighton using MODFLOW for <br />the purpose of siting additional wells and determining the timing and location of stream <br />depletions. <br />Evaluation of the potential yield of a Montana ground water basin for a large industrial facility <br />using MODFLO W. <br />Creation of an analytical spreadsheet model of the Phoenix Basin that involves annual surface <br />waterfground water interactions from ] 859 - 1998. The mass balance is currently being used to <br />develop a MODFLOW ground water model that will be used to evaluate Arizona water rights <br />issues. <br />Representing a mountain municipality whose water supply was impacted by petroleum <br />hydrocarbons; evaluated corrective action plan using MODFLOW. <br />Designing and observing drilling and testing of several alluvial wells (yielding 150 to 3,000 gpm) <br />and numerous mountain bedrock wells. <br />Exhibit 4 <br />LEONARD RICE ENGINEERS.
