Objectives of the industrial wastes program are: (1) to assemble basic information on those industrial wastes having national or regional significance; (2) to determine, in the light of stream uses, the physical, chemical, and biological effects and rates of recovery from effects of industrial wastes in the receiving waters; (3) to develop and improve analytical methods, techniques, and equipment for studying industrial wastes and their effects on receiving waters; and (4) to evaluate control methods and undertake miscellaneous activities. Coordinated efforts are required to achieve these goals. Data on pollution effects and stream recovery are gathered from literature reviews, research laboratory activities, stream surveys, analytical methods, bioassay techniques, and population enumeration methods. Specific areas in which the Technical Task Committee on Industrial Wastes can contribute are outlined.
