John Shomaker and Associates, Inc., Water-Resource and Environmental Consultants (JSAI) specializes in hydrogeologic investigations, water-supply planning, siting and completing water-supply wells, environmental hydrogeology, and water rights investigations.  JSAI has been serving communities in New Mexico, Texas, Arizona, and Colorado for over 30 years.  JSAI offices are located in Albuquerque, New Mexico.
John Shomaker, Ph.D.
Principal Hydrogeologist John W. Shomaker, Ph.D.has over 37 years experience in hydrogeology, including 4 years with the U.S. Geological Survey Water Resources Division, in Albuquerque, 4 years with the New Mexico Bureau of Mines and Mineral Resources (part of which was devoted to coal-reserve studies), and over 27 years as a consultant in hydrogeology. Since formation of JSAI, he has administered the firm’s projects. These have included large-scale drilling projects, such as the Cherokee & Pittsburg Coal and Mining Co. (Santa Fe Industries) 1975-1980 exploration program in the San Juan Basin, which resulted in eight test-and-production wells ranging from 2,221 to 5,747 feet deep. John Shomaker organized and supervised all of the work on footage-and-daywork contracts, purchased and scheduled all third-party supplies and services, and provided project management and accounting. He has also administered all of the JSAI projects described elsewhere in this summary, including ground-water modeling studies, water-planning studies, and well-drilling projects.

His education includes B.S. and M.S. degrees in geology from University of New Mexico (1963 and 1965), a M.A. degree in the liberal arts from St. John’s College, Santa Fe (1984), and M.Sc. and Ph.D. degrees in hydrogeology from University of Birmingham, England (1985 and 1995). He completed the U.S. Geological Survey Training Program in Hydrology in 1966. He is a registered geologist in Arizona (No. 16,481), Arkansas (no. 482), and Wyoming (PG-182). Geologists are not registered in New Mexico. He is certified by the American Institute of Professional Geologists (CPG-2405), the American Institute of Hydrology (CPH No. 315), and the Association of Ground Water Scientists and Engineers (CGWP No. 414), and is a member of many other professional organizations.

His work has included collection of ground-water related information since 1965, during employment with the U.S. Geological Survey. He has prepared and supervised numerous ground-water modeling studies. He taught ground-water hydrology for several years as an adjunct faculty member in the Department of Earth and Planetary Sciences, and in the Master of Water Resources Administration program (MWRA), at the University of New Mexico, and continues as a member of the MWRA steering committee and member of several master’s thesis committees.
