Two-hundred years of hydrogeology in the United States

January 1, 1994

The Hydrogeology Division of the Geological Society of America (GSA) sponsored a symposium entitled ' Hydrogeology in the United States, 1776- 1976 ' at the annual meeting of the GSA on November 9, 1976. The symposium was organized to provide a forum for discussion of major eras in the history of American hydrogeology and to contribute to the bicentennial celebration of the founding of the United States. Presentations were broken down into 3 sections: The Early Era (with a tribute to Oscar E. Meinzer), 1776-1920; Meinzer Era, 1910-1940; and the Modern Era (including scientific advantages; the quantification of hydrogeology; geochemistry; surface and borehole geophysics; and hydrogeology, policy, and politics) 1940-1976.
