Proposed are various indexes of pollution which attempt to determine priorities in removing environmental stresses. (CP)

This class project led to a solution for homeowners' pollution. (Editor)

Considers reasons for water, air, and land pollution in the Soviet Union, incentives to pollute under socialism and the advantages socialism has for environmental management. Concludes that industrialization, not private enterprise, causes environmental disruption, and that strongly centralized planned economics do not necessarily avoid…

The shortage of trained manpower remains a troublesome problem that must be overcome if the national attack on water pollution succeeds. The total number of persons treating waste water in 1967 was 11,300 professionals, 10,300 technicians, 23,500 sewage treatment plant operators, and 50,000 maintenance workers. (BC)

The water shortage problem can only be met by creating a linkage among water supply, sewage disposal, and storm-water control. At present, these basic components of water management are typically handled separately, as if water were an unlimited resource the use of which does not require much foresight. (RM)

Listed are available control parameters including basic definitions and concepts and methods of measurement. The application of these parameters to the control of water and wastewater treatment plants is also outlined. (CS)

Turbidity problems which originate in water treatment plants and the use of control turbidimeters to reduce health hazards from water-borne diseases are considered. (CS)

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)

Demonstrates the mathematical nature of a pollution problem in a marine environment. Includes reproducible student worksheets. (11 references) (MKR)
