Abstract: The report summarizes progress on geologic and hydrologic research related to the disposal of radioactive wastes. The research is described according to whether it is related most directly to (1) high-level and transuranic wastes; (2) low-level wastes, or (3) uranium mill tailings. Included is research applicable to the identification and geohydrologic characterization of waste-disposal sites, to investigations of specific sites where wastes have been stored, and to studies of regions or environments where waste-disposal sites might be located. A significant part of the activity is concerned with techniques and methods for characterizing disposal sites and studies of geologic and hydrologic processes related to the transport and (or) retention of waste radionuclides.

From Introduction: "Material for this report was gathered during the last quarter of 1928 and the first quarter of 1929, when the author visited the quick-silver-producing districts of California, Nevada, Texas, Oregon, Washington and Arizona to view the progress made in recent years and gather material for a comprehensive study of the present-day quicksilver industry of the United States."

From introduction: "In this paper are assembled and summarized many subjects relating to the copper industry in North America. Production of mines and districts, history of the industry in North America. Production of mines and districts, history of the industry, geology, of the principal deposits, and mining methods and costs are discussed."

Report issued by the U.S. Bureau of Mines discussing materials surveys conducted on mercury. As stated in the foreword, "the surveys dealing with metals and minerals summarize the demand-supply position in the United States and include information on production, imports, consumption, exports, substitutes, and pertinent history" (p. v). This report includes maps, tables, illustrations, and photographs.
