ng with reclaimed water, there remain both real and perceived risks to human health and environmental quality stemming from residuals in the treated wastewater. Proactively addressing these risks requires automating the distributed observation and control of the irrigation water and the trace pollutants that it conveys, including suspended or dissolved solids (TDS), colloidal solids, pharmaceuticals, organic carbon, pounds, pathogenic anisms, and nutrients such as nitrogen or phosphorus. A water reuse site in Palmdale, California is being used as a testbed for a work with soil moisture, temperature, and nitrate sensors. work focuses on two things: first, ensuring that environmental regulations are being met, and second, providing feedback to a water control system in order to optimize water
