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

A report by O. E. MEINZER, published as Appendix B of the annual report of the Committee for 1942–43 [Trans. Amer. Geophys. Union, Part II, pp. 418–420, 1943], describes in some detail the previous work of the United States Geological Survey and cooperating agencies on ground water for war purposes.

The geologists from the staff of the Geological Survey listed in that report and several other ground‐water geologists have served in the Army during the past year on water‐supply assignments. Only sketchy and unofficial information is as yet available concerning the activities of these geologists, but it is believed that they are now all engaged in overseas theaters of warfare and that their services in water‐supply and other technical work are of substantial value. In this service they have been supported by ground‐water maps and reports furnished by the Geological Survey for the different theaters.
