In May 2014, the National Ground Water Association (NGWA) held a conference on deep groundwater in association with the Ground Water Research and Education Foundation (GWREF). The purpose of the conference was to bring together investigators from different segments of the hydrogeological community and the oil, gas, and mineral industry that have an interest in characterizing deep groundwater resources, particularly areas underlain by sedimentary basins. The event provided a forum to share ideas on how to characterize deep groundwater, what we know today, and what we should be doing in the future. Discussions took place under two broad areas: (1) analysis of data and information to characterize hydrogeologic settings, water quality and flow in deep groundwater systems, and (2) tools and methods for collecting samples and in-situ hydrologic data for deep groundwater systems. This paper presents a summary of these discussions.

Michael Wireman is retired from the U.S. EPA where he served as a National Groundwater Expert. He has a master’s degree in hydrogeology from Western Michigan University. In his current position he provided technical and scientific support to several EPA programs, other federal agencies, international programs, and to state groundwater programs. Wireman has significant experience in the legal, scientific, and programmatic aspects of groundwater management. He is a member of the Colorado Ground Water Association, the National Ground Water Association, the Geological Society of America, and is the Chair of the North American Chapter of the International Association of Hydrogeologists.
Mary L. Musick, PG
Musick Groundwater Consulting, Wimberley, TX
Mary Musick has 30 years of experience in protecting groundwater quality. While working for the Texas Commission on Environmental Quality, she developed policies, rules, and guidance documents to prevent contamination of groundwater resources and chaired the Texas Ground Water Protection Committee. Her background also includes uranium exploration, mapping regional and statewide aquifer water quality, conducting contamination evaluations at hazardous waste sites, and developing various groundwater dependent endangered species policies and evaluations.
