Dissolved mineral matter in surface‐waters

The only unpublished comprehensive Geological Survey records of dissolved matter in surface‐waters are the results obtained in the study of the Colorado River and its tributaries since 1930. The records are mainly analyses of 10‐day composites of daily samples, although there are several analyses of spot‐samples from some streams in the basin and about 4000 single determinations of chloride or sulphate in daily samples. The need for a large number of analyses is shown by the fact that during the period 1925–35 the quantity of dissolved solids in 10‐day composites from the Colorado River at Grand Canyon ranged from 226 parts per million for June 11–20, 1929, to 1889 parts per million for. September 21–30, 1934. A series of analyses covering a whole year might be misleading. The weighted averages for the different years ranged from 491 parts per million for the year ending September 30, 1928, to 960 for the year ending September 30, 1934.

Quality of water in Colorado River in 1925-1926

Most of the analyses given in this report represent composites of daily samples collected by the observers at United States Geological Survey gaging stations on Colorado River at Grand Canyon and Topock, Ariz. These stations are operated under the direction of W. E. Dickinson, district engineer of the Geological Survey at Tucson, Ariz., who personally collected some of the samples at other points and arranged for the collection of others.

Temperature of water available for industrial use in the United States: Chapter F in Contributions to the hydrology of the United States, 1923-1924

The importance of water supply as a limiting factor in industrial development is becoming more evident each year. The limitation in a particular instance may be the quantity of water available, the quality determined by the mineral matter in solution or in suspension or by organic pollution, or the temperature of the water. Generally it is a combination of two or more of these factors. Many publications of the Geological Survey give data in regard to the quantity of surface water and ground water obtainable at different points. Other publications of this Survey and of other organizations give data on the quality of waters available for industrial use. The temperature of these waters is discussed in the present report. Data in regard to ground water have been obtained from Geological Survey water-supply papers, from the publications indicated in footnotes, and from an unpublished compilation of temperature records prepared by C. E. Van Orstrand, of the Geological Survey, in connection with studies of deep earth temperature. Data on temperature of surface water have been obtained mainly from officials of waterworks, as noted in the accompanying table. Data on air temperature have been obtained from reports of the United States Weather Bureau. The maps showing temperature of ground water and surface water (Pls. VIII and IX) are taken directly from Weather Bureau charts of temperature distribution.
