本文总结了一项健康影响研究（HES）的结果。HES代表了大量研究工作的成果，以评估与城市现有原水供应相关的再生水潜在健康风险。该研究包括识别、表征和量化传染病病原体和潜在有毒化学品的要素，以及筛选已处理废水和城市未处理饮用水供应中存在的化学混合物的致突变性和生物累积性的要素。未经处理的水源，以进入米拉玛水处理厂的原水为代表。该研究还包括一项可靠性分析，使用来自示范水回收厂单元工艺技术性能评估的数据。 此外，评估还包括进行流行病学研究，以收集圣地亚哥人口的基线数据，并对这两种水进行化学风险评估。每个研究要素的结果摘要如下。

This paper summarizes the results of a Health Effects Study (HES). The HES represents the product of a substantial research effort to estimate the potential health risk associated with reclaimed water relative to an existing raw water supply to the City. The study included elements for identifying, characterizing, and quantifying infectious disease agents and potentially-toxic chemicals, and for screening mutagenicity and bioaccumulation of the chemical mixtures present, in both the treated wastewater and the City's untreated potable water supply. The untreated water supply represented by raw water entering the Miramar water treatment plant. The study also included a reliability analysis, using data from the technical performance evaluation of unit processes in the demonstration water reclamation plant. Also, the evaluation included conducting an epidemiology study to collect baseline data of the San Diego population and conducting a chemical risk assessment on both water. A summary of the results from each of the study elements is presented.
