D3 Geochemistry was founded by Drummond "Dusty" Earley III, Ph.D.  He has a B.A. in Geology from the University of Maine plus M.S. and Ph.D. degrees in Geology and Geochemistry from the University of Minnesota and is a registered Professional Geologist in the State of Utah.  After completing his published dissertation research and field work in Colorado, he joined the U.S. Bureau of Mines in 1988 and worked there as a researcher in the Advanced Mining, In Situ Systems Group until the Bureau was closed by Congress in 1996. During his tenure with the Bureau he worked on the Santa Cruz In Situ Copper Mining Project in Casa Grande Arizona and other mining technology development projects related to the Bureau's mission to ensure mine worker health and safety and security of critical and strategic minerals for the US.  In addition to analytical geochemistry and mineralogy, he became very interested in coupled geochemical reaction and groundwater flow modeling during that period as the computer and modeling software capabilities expanded tremendously making commercial applications practical.  He launched his next career as a geochemical consultant to the mining and environmental industries by applying his expertise in geochemistry, hydrology, and computer modeling to a large range of projects in North and South America involving geochemistry and hydrogeochemistry investigations.  Most of his project experience is in acid mine drainage characterization, prediction and prevention, surface and groundwater quality compliance, and mine influenced water treatment.  Other significant projects involve seepage characterization, groundwater and pit lake modeling, and vadose zone characterization and modeling.  He is actively engaged with the mining, environmental, and earth science community and has published a book and many articles in scientific and trade journals and conference proceedings.  Dr. Earley has dedicated his career to the sustainable development of mineral and water resources.  In addition, he has mentored many junior professionals starting their careers in Earth Sciences.
