Abstract:
Continuing expansion and intensification of urban and metropolitan development in semi-arid regions of the Southwest (like Tucson and Phoenix areas) are adding new dimensions to the problems associated with water supply and management. Continual decline in ground water levels and impairment of the ground water quality associated with it have now become a major concern. Urban storm runoff comprises a potentially useful water source for domestic, recreational or other uses. In the semi-arid Southwest, due to generally higher temperatures prevailing in that region and the intermittent nature of rainfall and runoff, a great portion of this source is lost in wetting the ground surface and sand in the channels and through subsequent evaporation before it can substantially contribute to ground water. Storage and utilization of this source will require knowledge about the quality of the water it contains. The present study represents an attempt to determine the quality of water that flows through the city drainageways from different types of areas such as domestic, commercial and industrial. The results of this study are based on the analysis of runoff samples collected during the summer and winter rainy seasons of the year 1969 from three different types of watersheds in Tucson selected by the Water Resources Research Center in association with the Department of Civil Engineering at The University of Arizona. The samples were analyzed for various parameters of pollution and also for usual mineral constituents. The results of the analyses have been discussed and compared with other studies. It was evident that some degree of treatment was needed for future utilization of these waters. This study also attempts to note the effects of simple treatment of aluminum sulphate (alum) on large samples collected from two watersheds. The effects of treatment on turbidity, chemical oxygen demand and densities of bacterial indicators of pollution have only been noted.
