After 30 years of working for the USGS in various capacities, 5 years as Scientist Emeritus, Nathan is back -- as a rehired annuitant working through database issues and providing project advice and assistance.
Nathan received his B.S. degree in Geology from the University of Missouri, Rolla and his M.A. Degree in Geology (Antarctic Geoscience) from Rice University. Subsequently Nathan spent a short stint working for Amoco Production Co. in Houston before starting with the USGS in Lawrence KS (now the KS Water Science Center). Nathan worked for the KS office for 12 years before moving to New Mexico in 2000. Nathan's work in NM has included overseeing groundwater projects at military installations, groundwater-surface water investigations in the Hondo Basin, and development of a child model to evaluate potential impacts of a Kirtland Air Force Base fuel plume on municipal supply wells. Since retiring in 2018 Nathan has been very involved in updating the groundwater database for NM, coordinated and led a geohydrologic field trip of the Albuquerque basin, and has been active in the Tijeras Creek Collaborative group that is seeking to make watershed improvements. In 2022 Nathan published a statewide assessment of groundwater levels in New Mexico using a series of composite hydrographs to characterize water-level changes over the past 40 years.
