Research Impact

As water supply becomes more limited throughout the world, there is an interest in innovative approaches to water resources sustainability. One approach gaining popularity is household graywater reuse for residential landscape irrigation. While some states have begun to legalize and regulate graywater reuse, little guidance based on scientific data has been provided for the safe operation of graywater irrigation systems. The objective of this research was to examine the fate and occurrence of graywater constituents and their potential impacts on soil and groundwater quality and plant and human health as a result of its use for residential landscape irrigation.
