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…

Regional and supraregional treatment centers have been developed in Switzerland to cope with the problem of systematic toxic waste disposal. The process employed at the Fairtec Turgi plant is described beginning with delivery and storage and proceeding through treatment, reprecipitation, decontaminating cyanide, filtering sludge and ion-exchanger…

Discusses the roles of leading firms, consulting engineers and equipment manufacturers in the growing field of water pollution control. Reviews of individual companies are given. (BL)

Most waste treatment techniques conceived to meet the 1977 standards can be separated into three distinct phases: primary, secondary and tertiary treatment. An examination of the four heaviest industrial water users, pulp and paper, steel, plating, and food processing, demonstrates these treatments use proven technology to meet specific…

Industry is faced with handling, disposing and recovering vast amounts of waste, much of it as a result of present pollution control technology. Industry has found the technology available, expensive and, without regulation, easy to ignore. Many industries are therefore improperly managing their wastes. (BT)

Headquartered at Joliet, Illinois, the Army Ammunition Procurement and Supply Agency aims to mechanize and clean up its manufacturing facilities. Six go-co (government owned - contractor operated) plants involved in the modernization program are described. (BL)

A report on the increasing usage of chemicals in water treatment, particularly the use of coagulants and flocculants. (BB)

The test procedures used to evaluate the suitability of landfilled materials of varying stability and to determine the leachate from such materials are reviewed. A process for stabilizing a mixture of sulfur dioxide sludge, fly ash, and bottom ash with lime and other additives for deposition in landfills is detailed. (BT)

Increasing population and industrialization places heavy demands on water resources making recycling of wastewaters for domestic consumption inevitable. Eliminating human pathogenic viruses is a major problem of reclaiming wastewater. Present water treatment methods may not be sufficient to remove viruses. (MR)
