Bill’s professional accomplishments include conducting in-depth studies of the relationship between groundwater pumping and baseflow in many Arizona stream/river systems, including the Little Colorado, Verde, Salt, River, Gila, Santa Cruz, and San Pedro Rivers, as well as tributary creeks. Recently, he developed a groundwater flow model for the Big Chino Valley to support an application for modifying the City of Prescott’s Designation of Assured Water Supply (DAWS), successfully defend- ing the model in appeals court. He has also assisted several Native American tribes with water supply studies and water rights disputes. Among these cases are the Northern Arizona Indian Water Rights Settlement Agreement to resolve claims that the Navajo Nation and Hopi Tribe may have to the Little Colorado River and to surface water and groundwater in the LCR watershed. He has also provided testimony on ground/ surface water interrelationships in cen- tral Arizona alluvial basins for the Gila River adjudication proceedings.
Throughout his 28-year career with Dames and Moore, Bill served as both principal investigator and project man- ager. He directed and participated in more than 50 investigations at 18 nucle- ar power plant sites, which included evaluating the potential for contaminant transport, and participated in studies of environmental compliance, dewater- ing, stormwater diversion, and leachate collection systems for mines. He joined Southwest Groundwater Consultants (now Matrix New World Engineering Southwest Groundwater) in 1997, where he serves as Principal Hydrogeologist.
