Technical report issued by the Bureau of Mines over the different uses of gypsum. The sources and uses of gypsum are presented and discussed. This report includes tables, photographs, and illustrations.

This research project is aimed at assessing the soil organic carbon (SOC) sequestration potential of reclaimed minesoils (RMS). The experimental sites, owned and maintained by the American Electrical Power, are located in Guernsey, Morgan, Noble, and Muskingum Counties of Ohio. These sites, characterized by age chronosequences, were reclaimed with and without topsoil application and are under continuous grass or forest cover. During this quarter, bulk and core soil samples were collected from all 13 experimental sites for 0-15 cm, 15-30 cm, and 30-50 cm depths. In addition, 54 experimental plots (4 x 4 m) were established at three separate locations on reclaimed minesites to assess the influence of compost application on SOC during project period 2. This report presents the results from two sites reclaimed during 1978. The first site is under grass and the other under forest cover. The soil bulk density ({rho}{sub b}), SOC, total nitrogen (TN) concentrations and stocks were determined for these two sites on a 20 x 20 m grid. The preliminary analysis showed that the {rho}{sub b} ranged from 0.88 Mg m{sup -3} to 1.16 Mg m{sup -3} for 0-15 cm, 0.91 Mg m{sup -3} to 1.32 Mg m{sup -3} for 15-30 cm, and …

From introduction: The purpose of this report is to describe the geology of the rocks in the different sedimentary basins in relation to problems of disposal of liquid radioactive wastes in the ground.

Report discussing the uranium content evaluation of coals and shales collected in eastern Ohio. Information regarding the scope of the investigation, stratigraphy of the areas of collection, results of the radioactivity evaluation, and conclusions are included.

The following report is a quarterly report by the Monsanto Chemical Company for liquid waste disposal research, covering the period between April 1 to June 30, 1949.

The following report is a quarterly report conducted by the Monsanto Chemical Company for liquid waste disposal research, covering the period April through June, 1950. This report discusses experiments that were carried out with both neutralized second-cycle wastes and pure isotope which show that, in general, the presence of fluoride ion does not interfere with the removal of fission products from waste solutions.
