摘要:

This annex, issued in April 1960 by the Office of Civil and Defense Mobilization, supports and amplifies the National Plan for Civil Defense and Defense Mobilization, particularly Part VI, Sec. F, “Management of Resources After Attack on the Continental United States.” It outlines responsibilities for providing, treating, and safeguarding water for all essential purposes during an emergency, together with procedures for the emergency operation of water resources facilities.

摘要:

To investigate the water solubility question more thoroughly, the US Army Engineer Research and Development Laboratories (ERDL), in cooperation with the Office of Civil and Defense Mobilization, conducted studies in the summer of 1957 at the Atomic Energy Commission's Nevada test site. The studies were part of “Operation Plumbbob” and were reported by ERDL. Radioactive bomb debris was collected at the Nevada test site from the nuclear‐shot “Priscilla” on June 24, 1957. The article discusses nine solubility experiments that were conducted on the radioactive bomb debris, along with experimental results and evaluation of data.

摘要:

Adequate service meeting the needs and desires of the customer must go hand in hand with improved customer relations. Criteria adopted for the sizing of residential services must take into account many technical considerations and the important factor of public relations. Besides the reaction of customers within the central city, the support of officials of suburban areas is of utmost importance. This is particularly true where acceptance and application of proposed or revised standards is involved. At the same time, an educational campaign must be conducted that will explain the increased costs that almost inevitably result from such service. Increasing the minimum size of residential services may well result in an increased cost of service, but it is believed that a fully informed public will support this action.

摘要:

Sizing a meter requires that the interests of both the customer and the supplier be equally considered. Determination of demand is predictable to a degree commensurate with the completeness of information about the service required. Selection of the correct type and size of meter for a demand of known type and magnitude can be made a matter of routine. Many of the problems of sizing meters can be eliminated by the adoption of general rules or policies governing the use of different types of meters. At Houston, the use of displacement meters in only the small sizes and the use of compound meters in all the larger sizes have, by routine policy, reduced the number of instances when meters have been either overworked, with consequent excessive wear, or oversized with resulting under‐registration.

摘要:

This article begins by discussing how major water supplies or systems in Peru have been financed and built in the past by direct grants from the national government. However, national financial support of this nature is not able to keep up with rapid growth in demand, and few water systems in Peru are self‐supporting in operating costs alone. The author describes his experience where, during the summer of 1960, he spent 5 weeks in Peru as a short‐term consultant to the International Cooperation Administration (ICA), activities of which are known as the Point Four program. The consultation was a part of the Community Water Supply Development Program of ICA. Under this program, and in collaboration with the World Health Organization and the Pan American Health Organization, ICA is assisting cooperating countries to develop or strengthen business‐type, self‐sustaining national institutions that will plan and aid financing, construction, and management of water supply systems at the community level.

摘要:

As a result of a request by a large industrial user for a water supply that meets quality standards considerably more stringent than those applied to public drinking water, a 6‐year program involving numerous studies, tests, and plant changes and additions was undertaken by the Old Dominion Water Corporation in Hopewell, Virginia. The high‐quality water requested was to be used in producing a premium grade of nitrocellulose. This article discusses the improvement in water quality from 1955 to 1960 that was brought about mainly by introducing free residual chlorination, pH correction before filtration, the use of activated silica, the development of laboratory control procedures, and the provision of laboratory and plant recording instruments.

摘要:

As waterborne bacterial diseases continue to decline and the bacteriologic quality of water supplies continues to improve, waterborne infectious hepatitis attracts more and more attention of public health and sanitary workers. Municipal water supplies are found to carry, not infrequently, live free‐living nematodes and amebic cysts. This study examines the literature and current research on these microbes to evaluate the public safeguards against municipally waterborne virus diseases and the provision of high quality public water supplies. The basic biologic characteristics of viruses, amebas, and nematodes are discussed, along with data on the number and extent of waterborne epidemics of infectious hepatitis reported in the U.S. and abroad.

摘要:

The Association of American Soap and Glycerine Producers (AASGP), New York, initiated a study in 1955 of traces of alkyl benzene sulfonate (ABS) found in rivers and public water supplies through the use of household detergents. ABS is the sodium salt of commercial sulfonated dodecylbenzene and is the most commonly used synthetic surface‐active agent in formulated household synthetic detergents. A technical subcommittee was formed in 1959 to establish quantitatively the concentrations of ABS that may be present in municipal drinking water supplies. With the use of recognized surveys, a study was prepared of the normal varieties of drinking water supplies in 32 cities throughout the United States. The selection of test cities was based on raw water source, location, treatment method, and population. The cities chosen represent roughly one‐eighth of the population of the United States.
