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…

Citizen action to stop the disposal of taconite tailings into Lake Superior was unsuccessful when the courts settled in the favor of industry. Although citizen research revealed a form of asbestos, as well as other toxic chemicals in the discharged wastes, company representatives stated that there were no health hazards. (MA)

The techniques of thermal sterilization and sterilization by filtration and reverse osmosis are discussed. (BB)

Responses of two experts to questions concerning wastewater plant operation and maintenance are presented. The responses discuss the scarcity of good personnel, training education available, and examples of existing improvement projects. (MA)

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…

Papers are presented identifying fundamental research needs in water and wastewater treatment by industrial users of technology, industrial users of research, a municipal water department, a consulting engineer, Congress, and the EPA. Areas of research needs addressed include: (1) microbial, viral, and organic contaminants; (2) biological…

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

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)

This is an annotated bibliography of wastewater treatment manuals. Fourteen manuals are abstracted including: (1) A Planned Maintenance Management System for Municipal Wastewater Treatment Plants; (2) Anaerobic Sludge Digestion, Operations Manual; (3) Emergency Planning for Municipal Wastewater Treatment Facilities; (4) Estimating Laboratory Needs…

Describes over 30 guidelines and principles of effective grant writing. (MA)

Describes is an improvement program for the operation and maintenance of municipal wastewater treatment plants in Detroit, Michigan. Improvements included expansion and upgrading of the existing city plant and a training program for plant personnel. (MA)

This article describes procedures taken by the U.S. Navy to minimize the environmental import and pollution in harbors and coastal areas resulting from ships, aircraft and shore-based Navel operations. (SL)

The Second National Conference on Complete WateReuse stressed better planning, management, and use of water. The sessions covered: water reuse and its problems; water's interface with air and land, and modification of these interactions by the imposition of energy; and heavy metals in the environment and methods for their removal.

Plants found in marshlands and wetlands in many parts of the world may play an increasing part in a very new, yet very old approach to treatment of water and wastewater--the application of biological methods. Biological water pollution control methods being utilized around the world are examined. (BT)
