Dr. Jenson’s research encompasses both applied and fundamental aspects of island groundwater hydrology and related environmental science. Recent work on Guam’s groundwater resources includes assessments of sinkholes and other drainage features on new constructions sites, evaluation of newly-drilled and rehabilitated wells, evaluation of rehabilitation potential for long-out-of-service wells, and reconnaissance of promising sites for new production wells in Guam’s 120+ production-well system. Past applied work includes a comprehensive hydrogeological evaluation of the stormwater drainage potential of a large sinkhole on Andersen Air Force Base, adjacent to an aircraft parking facility. Recently completed work includes a hydrogeologic study of Santa Rita Spring to provide engineering design recommendations for rehabilitation, and a numerical modeling study to evaluate sustainable yield from the Northern Guam Lens Aquifer. Recent work also includes a hydrogeologic field study of the Finegayan Basin, northwest Guam; a field study of vadose percolation in the aquifer; and a long-term study of salinity patterns and trends in Guam’s production wells. Basic geological projects have included mapping the geology of the Northern Guam Lens Aquifer and updating the general geologic map of Guam. Previous regional work includes field and numerical modeling studies of atoll island aquifers in the Caroline Islands. From 1997 through 2013, Dr. Jenson collaborated with Dr. John Mylroie of Mississippi State University to develop and apply the Carbonate Island Karst Model to the region’s tectonically active limestone-capped islands: Guam, Saipan, Tinian, and Rota in the Mariana Islands, and Fais, the one raised limestone island in the Caroline Islands. Work on Fais also included a survey of water resource potential, water-use patterns, and recommendations for integrated use of groundwater wells and rainwater catchments for meeting routine and emergency needs. Dr. Jenson’s basic scientific research activities also include collaborative work with Dr. Jay Banner, University of Texas-Austin, to characterize Guam paleoclimate from speleothems and corals, along with related topics, including sea-level history, coastal speleogenesis and the hydrogeological evolution of the aquifer.
