Abstract: The City of San Diego, California has received Clean Water Grant funding to build and operate a 0.5 million gallon per day facility to demonstrate a wastewater treatment system, utilizing a unique combination of treatment methods, to treat wastewater to a quality which may be acceptable for human consumption. The study includes a comprehensive attempt to measure as many as possible of the parameters which may effect the risk associated with potable reuse of municipal wastewater, after treatment to a very high quality in a state-of-the-art advanced wastewater treatment system. The study also includes comparison of the risk relative to that associated with the City's present water supply. The purpose of this paper is to present the preliminary results and findings from the monitoring effort. The discussion includes monitoring results relative to bacterial, viral and parasitic disease agents, routine bacterial indicator organisms, chemical screening, and genetic toxicity testing.
