The Public Health Service has studied the Potomac River Basin water requirements for present and future water supply and quality control. The results are as follows 1 There is a need for development of water resources to provide storage for water supply and quality control 2 Adequate treatment of all wastes is required before returning treated effluents to the stream. 3 It is apparent that we do not have a technically practicable and economically feasible means of removing all pollutants. Even after adequate treatment of wastes, natural flows will be insufficient to assimilate the treated residual and attain desired water quality objectives in many stream reaches of the Potomac River Basin and 4 With present knowledge the most practical method of maintaining stream quality after adequate treatment of wastes is increased stream flow from stored water. No known conventional waste treatment method, by itself, exists which will provide stream conditions comparable to that obtained with conventional treatment supplemented by increased stream flow for control of dissolved oxygen, color and persistent waste substances.
