  • Promote international activities which further the science and technology of hydrogeology and water resources.
  • Promote research, education, communication, and training in groundwater science.
  • Stimulate the interest of hydrogeologists in the U.S. in international hydrogeological activities and better acquaint hydrogeologists abroad with the concepts and techniques developed and applied in the U.S.
  • Coordinate interest and activities among hydrogeologists in the U.S. with IAH programs and activities.
  • Maintain liaisons with other groups concerned with international water-related activities in general and hydrogeology in particular.
  • Provide a link between the international groundwater community and hydrogeologists in the United States.
