Appendix B—The work of the Geological Survey and cooperating state agencies on ground water for war purposes

Abstract

The very large service which the geologists and engineers trained in ground‐water hydrology are rendering in this country in the prosecution of the war is due largely to the effective organization for this purpose. The Federal agency in which this service centers is the Water Resources Branch of the United States Geological Survey. The Ground Water Division of this branch has a technical personnel of nearly 100 geologists, engineers, and physicists, and its work is supported by the chemists of the Quality of Water Division and the engineers of the other Divisions of the Branch. It functions through a central office in Washington and 25 widely distributed field‐offices. Moreover, this service is effectively supported by the State Geological surveys, State Engineer offices, and other State agencies concerned with water‐resources, not only in the 34 States in which there is formal cooperation with the Federal Geological Survey in ground‐water investigations but also in those States in which there are no formal cooperative agreements. The magnitude of the civilian service rendered is indicated by the fact that to date about 1,600 reports on water‐supplies from wells have been made to the War and Navy Departments and other war agencies by the Geological Survey and cooperating State organizations.
