To add to the understanding of, and clarify the issues surrounding the safe and effective use of household graywater, the Water Conservation Alliance of Southern Arizona conducted an in-depth study of residential graywater reuse in the greater Tucson area of the Southwest United States. The study, supported by the Arizona Department of Water Resources, the Arizona Department of Environmental Quality, and the Pima County Department of Environmental Quality, looked at two separate aspects of graywater usage in the region: survey of households currently using some portion of the graywater they generate; and, testing the water quality of the residential graywater being generated and how that water quality affects the soil that is irrigated with that water. This paper discusses the results of this study. Includes 16 references.
