MARC is an international organization designed to advance the understanding of environmental processes and aid in the design of monitoring systems for environmental management and research. This article reviews the work done by MARC in its first two years of existence and makes suggestions for expanding the program. (Author/MA)

Dispersion, chemical oxidation, and masking are reviewed as techniques primarily employed for odor control. Devices and systems, costs, and problems of measurement are considered in light of environmental agencies' efforts to curb smelly emissions. (BL)

Characteristics of ground water and aquifers are explained to facilitate understanding of their importance in domestic water supplies. Problems of over usage, contamination, and regulation are enumerated and a national protection policy is advocated. (BL)

Delegates of a working group on air pollution problems of the Economic Commission for Europe discussed the status of advanced technologies for controlling man-made emissions of sulfur dioxide. Technologies discussed included: coal washing, oil desulfurization, flue gas desulfurization, scrubbing, residual oil desulfurization, fluidized bed…

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…

The use of remote sensing to quickly detect and efficiently monitor environmental problems is discussed. Available technology, typical operations procedure, and film choice are detailed. (BT)

The Fossil Energy Program is attempting to develop and demonstrate, in conjunction with industry, the technology necessary for establishing a synthetic fuels-from coal industry. Technologies discussed include coal liquefaction, high and low BTU gasification, advanced power systems, direct combustion, Magnetohydrodynamics (MHD) and petroleum,…

Recent hearings have shed little light on how the federal government should restructure itself to deal with the mounting energy crisis. Individual viewpoints and personal observations are presented, showing a lack of consensus on the best way to accomplish this. Office of Science and Technology priorities toward a national energy policy are…

The instrumental method for detecting total organic carbon (TOC) in water samples is detailed. The method's limitations are discussed and certain precautions that must be taken are emphasized. The subject of TOC versus COD and BOD is investigated and TOC is determined to be a valid indication of biological demand. (BT)

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…
