The paper documents that return irrigation water is a major factor affecting the quality of surface and ground waters. The report discussed the quantity and quality of the water required for irrigation, the disposition and use of this water, the factors influencing the quantity and quality of the water returned to surface or ground supplies, and the effects of this return flow on further use of the supplies in a complex of multiple uses. The investigation has shown that the potential water quality problems involve changes in salinity and hardness, temperature, turbidity, nutrients and aquatic growths, odor and taste, nitrates, and sanitary quality. Each of these factors is developed and documented and the actual and potential effects on water uses are analyzed. The major water uses considered are domestic and industrial water supply, fisheries, recreation and irrigation.
