Darrel Dunn, Hydrogeologist - Geologist
I am an unaffiliated geologist and hydrologist with advanced education and extensive experience, including the sub-disciplines of hydrogeology, environmental geology, engineering geology, and petroleum geology. My office is located in the Colorado Springs - Denver area, USA. I am organized as a sole proprietor doing business as Darrel Dunn - Hydrogeologist (aka DunnHydroGeo). My office is equipped with a Windows PC and a Linux PC. I have a substantial professional library. I maintain a presence on the internet, and publish pages on this website dealing with hydrologic and geologic topics. I maintain Wyoming registration as a professional geologist. My office is 65 minutes from the Denver International Airport. I have done geologic and hydrologic work throughout the United States (see below), and foreign work in Canada and Africa. I use internet cloud services to share documents.
I have a Ph.D. from the University of Illinois, Urbana-Champaign, in geology/hydrogeology. My graduate level education includes courses in hydrogeology, engineering geology, petroleum reservoir engineering, stratigraphy, sedimentary petrology, sedimentation, and mathematics (advanced calculus, applied differential equations, advanced statistics). I have done independent consulting from offices in Colorado and Montana for engineering firms, mining companies, real estate developers, petroleum companies, agricultural firms, state and federal agencies, law firms, and private individuals. In addition to independent consulting, my experience includes (1) direct employment by universities (Montana State University and University of Toledo, Ohio) as a professor of geology and hydrogeology, (2) by two nationwide engineering firms working from offices in Colorado and Pennsylvania as a senior hydrogeologist and groundwater modeler, (3) by Broward County, Florida, as a senior hydrologist in water resource management including the development of a countywide integrated groundwater and surface water computer model, (4) by the Alberta Research Council Groundwater Division, and (5) by a major oil company as a petroleum geologist working on exploration and production in the Colorado, Wyoming, New Mexico, Nevada, Illinois, Saskatchewan, and Alberta .
I have been using computer applications throughout my career. I have developed programs in Fortran, Python, and other languages; and can operate from the command line of a Linux terminal. Computing proficiency supports the use of public and open-source applications, which may be more cost-effective and/or suitable than proprietary software. I have also developed original Fortran and Python code for special problems. I have extensive experience with groundwater and surface water modeling software, beginning with my Ph.D. Thesis and continuing to recent modeling.
Recent consulting topics include groundwater modeling, water resource assessment, slope stability, water well testing, water well construction, groundwater exploration, saltwater intrusion, springs, fractured aquifers, groundwater quality, and Colorado geology.
