International Association of Hydrogeologists

The International Association of Hydrogeologists (IAH) is a global organization dedicated to the science and practice of studying groundwater—the water stored beneath the Earth’s surface. It brings together scientists, engineers, and policymakers to share knowledge, promote sustainable management of groundwater resources, and address issues like water scarcity and contamination. IAH supports research, offers training, and develops standards to ensure safe and responsible use of underground water resources worldwide, helping communities and environments thrive through effective hydrogeological practices.
