Mr. Campbell is well-known nationally and internationally for his work as a technical leader, program manager, consultant and lecturer in hydrogeology, mining, and associated environmental and geotechnical fields. He has gained a wide range of interdisciplinary experience in business and technical management in the environmental (regulatory, geological and hydrogeological), mining, and financial fields spanning almost 30 years.

Mr. Campbell has published widely, most notably: Water Well Technology (McGraw-Hill) and Rural Water Systems Planning and Engineering Guide (Commission on Rural Water). In the mid to late 1970's, he served on the Editorial Board of the journal: Ground Water for eight years and served as cofounder and first Director of Research of the NWWA Research Facility at Rice University. In the late 1970's, he also produced Geology [and Environmental Considerations] of Alternate Energy Resources (Houston Geological Society) and many other publications and consulting reports over the years on a variety of applied hydrogeologic, geologic, and injection well and hazardous waste subjects. He maintains an extensive library of more than 300,000 citations on environmental and mining topics covering the U.S. and overseas.

Mr. Campbell interrupted his graduate studies after the master's degree (Ph.D. work at Rice University in 1976) to join a major engineering and environmental consulting company as Director, Alternate Energy, Mining and Environmental Programs. During the period, he also served as an invited technical expert and lecturer for UNESCO-sponsored water-supply projects conducted in many parts of the world. Mr. Campbell co-managed a mining project as operating financial officer (handling revenues/expenses of more than $8 million/year) and as technical officer for exploration, mining, processing/refining and environmental activities. Over the past 15 years, Mr. Campbell has provided senior technical guidance, review, training, litigation support and consultation on numerous hydrogeological, water supply, and hazardous waste projects involved in both RCRA and CERCLA programs for major law firms and consulting engineering and environmental companies as well as industry.
