The NGWA Hydrogeophysics and Deep Groundwater Conference was co-located with the Symposium on the Application of Geophysics to Engineering and Environmental Problems (SAGEEP) March 20-21 in Denver, Colorado, where presentations shared the enhancements to existing tools and methods used to locate and assess groundwater resources as well as newly developed techniques. Several presentations focused on the rapidly advancing applications of airborne electromagnetic platforms.
Andrea Croskrey, PG, of the Texas Water Development Board, delivered the keynote address on mapping brackish aquifers for future water resources in Texas. Croskrey was followed by 2017 Darcy Lecturer Kamini Singha, Ph.D., of the Colorado School of Mines who provided insights into use of geophysics to explore the connections between plant water uptake and the vadose zone and streamflow.
Panelists Lorrie Council of the Texas Commission on Environmental Quality; Hal Demuth of Petrotek Engineering Corp.; and Lily Lee of Wyoming Department of Environmental Quality addressed “The Aquifer Exemption Process: Implementation for Groundwater Protection and Use.” The panelists provided an excellent overview of exempt aquifers and the role of states. Significant discussion included the U.S. Environmental Protection Agency’s final review and approval authority of exempt aquifer requests.
