Events

IAH is actively involved with programs that provide a valuable forum for scientists and engineers who have a broad interest in global perspectives on groundwater resources and hydrogeological issues.

USNC Meetings

The USNC is affiliated with the American Geosciences  Institute (AGI), Geological Society of America (GSA), and National Ground Water Association (NGWA),  as these organizations also have international groundwater science interests. The USNC holds meetings at annual events of these other organizations to encourage networking among USNC members and others who are interested in promoting international cooperation among hydrogeologists and others with an interest in groundwater. The USNC periodically meets in the fall at the GSA Annual Conference.

Check thenext  USNC newsletter for meeting day and time announcements. Alternatively, check the onsite conference program or contact Tim Parker, Chair, at tim@pg-tim.com for meeting information.
