Participants in the D-19 symposium on aquatic sampling and measurement for water pollution assessment were informed that determining the extent of waste water stream pollution is not a cut and dry procedure. Topics discussed include field sampling, representative sampling from storm sewers, suggested sampler features and application of improved…

Several aspects and policy implications of the generation and collection of residential solid waste are investigated. The effects resulting from the imposition of user charges, improvements in the quality of service, and changes in the type of collector are examined. (Author/RLV)

Our present sewage disposal systems are ecologically unsound because they risk transmitting diseases, waste water, cost too much, increase lake eutrophication, and build up sludge. Sewerless toilets are being developed which can solve these problems. (MR)

This circular provides current information for homeowners who must repair or replace existing on-lot sewage disposal systems. Site requirements, characteristics and preparation are outlined for a variety of alternatives such as elevated sand mounds, sand-lined beds and trenches, and oversized absorption area. Diagrams indicating construction…

In 1972, a water quality survey of the eastern end of Majuro Atoll, Marshall Islands was conducted to determine the water quality of selected lagoon and open ocean sites and provide guidance for the construction of a sewerage system. This study revealed that lagoon waters were moderately to severely contaminated. (BT)

This report contains 568 selected abstracts concerned with the land application of sewage effluents and sludges. The abstracts are arranged in chronological groupings of ten-year periods from the l940's to the mid-l970's. The report also includes an author index and a subject matter index to facilitate reference to specific abstracts or narrower…

This publication contains information relating to waste prevention, treatment and disposal, and waste product utilization. Its primary purpose is to provide information that will help the food industry executive recognize waste problems and make wise management decisions. The discussion of the methods, techniques, and the state-of-the-art is…

This circular provides current information for homeowners who must repair or replace existing on-lot sewage disposal systems. Several alternatives such as elevated sand mounds, sand-lined beds and trenches and oversized absorption areas are discussed. Site characteristics and preparation are outlined. Each alternative is accompanied by a diagram…

This publication is a compiled and indexed bibliography of solid waste management documents produced in the last ten years. This U.S. Environmental Protection Agency (EPA) publication is compiled from the Office of Solid Waste Management Programs (OSWMP) publications and the National Technical Information Service (NTIS) reports. Included are…

The City of Washington, D.C., with federal funding, declared war on one of the city's most pressing problems--rats. The War on Rats Program, in conjunction with Operation Clean Sweep, made a city-wide survey of rat infestations and recorded the areas of heavy rat infestation. After the problem areas had been identified, community organizations…

Aerospace technology may have led to a unique basic unit for processing solid wastes and controlling pollution. The Combustion Power Unit--400 (CPU-400) is designed as a turboelectric generator plant that will use municipal solid wastes as fuel. The baseline configuration is a modular unit that is designed to utilize 400 tons of refuse per day…

A primary responsibility of field environmental health workers is evaluation of individual sewage disposal system sites. The authors of this article developed a practical, accurate, and inexpensive measurement device for obtaining reliable percolation test results. Directions for the construction and use of the device are detailed. Drawings…

For more than a decade, the Chinese have been using biogas digesters to produce fuel for homes in rural areas. This article discusses the design, operation, and benefits of these digesters. This means of waste treatment helps improve sanitation, produce fertilizer, and save fossil fuels. (MA)
