The report describes the priorities that have been selected in the Federal Marine Science program during 1969. The first chapter reviews the steps taken by the Federal Government during 1969 to advance and…

This book uses the 1962-66 Massachusetts drought data as a base of information to build a planning model of water resources that is of interest to students and professionals involved with water management. Using a demand-supply ratio to measure the relative inadequacy of a given water system, the authors then project demand into the drought period…

This report was prepared for the President of the United States by the Council of Environmental Quality. Location, quantities, composition, trends, pollution, and international aspects of ocean dumping are discussed. Also included are alternatives to dumping and legislative control. Recommendations are made dealing with policies, regulations, and…

Presented is information necessary to an electric utility company and electrical equipment manufacturer to ensure the proper combination of motor and starting equipment in a water-utility facility. (CS)

Discusses some of the physical processes involved in the freezing of water. Traces the work of a variety of researchers who have discovered numerous variables involved in the complexities of ice. (TW)

Describes a course designed to provide the necessary academic study prior to students engaging in the practice of irrigation engineering. Rationale for the course, course structure, and special features of the course are included. (JN)

The coastal waters of the Beaufort Sea are covered with ice three-fourths of the year. These waters (during winter) are discussed by considering: consolidation of coastal ice; under-ice water; brine circulation; biological energy; life under the ice (including kelp and larger animals); food chains; and ice break-up. (JN)

A recent conference of the National Environmental Development Association focused on the concepts of environment, energy and economy and underscored the necessity for balancing the critical needs embodied in these issues. Topics discussed included: nuclear energy and wastes, water pollution control, federal regulations, environmental technology…

A quantitative method for the determination of vinyl chloride in water is presented. Vinyl chloride is transfered to the gas phase by bubbling inert gas through the water. After concentration on silica gel or Carbosieve-B, determination is by gas chromatography. Confirmation of vinyl chloride is by gas chromatography-mass spectrometry. (Author/BT)

Automatic control of swimming pool chemical balance has saved the Arlington Heights, Illinois, school and park districts more than $5,000 a year since 1972. (Author)
