Abstract |
The purpose of this investigation was to obtain data to: (1) determine the oxygen relationships in the stream before and during ice coverage; (2) determine the rate of of oxygen depletion in the stream during ice coverage; (3) determine the suitability of relatively unpolluted streams for dilution purposes; and (4) determine the characteristics and quantities of the various wastes entering the river. It was found that the rate and extent of oxygen utilization by industrial wastes depends upon several variable factors, including the nature of the waste, temperature, extent of dilution, and the type of dilution water. |
