The Association of American State Geologists (AASG) represents the directors of the state geological surveys in the states and Puerto Rico. The responsibilities of each state survey varies, depending upon legislation and traditions. Most function as an information source for government and society. Some have regulatory roles for topics such as water, oil and gas, mining, and land reclamation.

The first state survey was established in 1823 in North Carolina. By 1840, there were at least 15 state surveys, most of which were charged with the discovery of mineral, energy, land, and water resources in their state or territory. The State Geologists began formal meetings with the U.S. Geological Survey in 1879, the year that organization was established. Since 1908, the Association has met regularly to discuss issues of common interest and to initiate united actions when warranted.

AASG History

The first state geological survey was established in North Carolina in 1823. By 1840, at least 15 state surveys had been established, many charged with identifying and understanding the mineral, energy, land, and water resources of their states and territories.

State Geologists began formal meetings with the U.S. Geological Survey in 1879, the year the USGS was established. In 1908, the Association of American State Geologists began meeting regularly, creating a national forum for State Geologists to address shared priorities, strengthen collaboration, and take collective action on issues of national importance.

Today, AASG represents the geological surveys of all 50 states and Puerto Rico. While the responsibilities of individual surveys vary by state, they share a common commitment to providing trusted geoscience in service to government, communities, and the public.
