采用多指标综合评价方法对2012年淮安市二河饮用水源地水质状况的评价，结果表明其水质满足饮用水标准；同时利用美国环境保护署（U.S.EPA）的水环境健康风险评价模型，计算了该水源地水体中污染物由饮水途径对人体健康危害的风险度，结果表明，化学致癌物质的个人年风险度远大于非致癌物质，各污染物的风险度从大到小依次为As>Pb>氟化物>硝酸盐>Mn>Fe>氨氮。研究成果可为二河饮用水源地的水质管理提供技术参考。

In this paper, the multi-index comprehensive evaluation method was used to evaluate the water quality of Erhe drinking water source region of Huaian city in 2012, and the results showed that the current water quality meets the standards of drinking water. The risk scales of water pollutants on public health were assessed using the Water Environmental Health Risk Assessment Model of U.S.EPA, which indicated that the personal annual risk caused by the chemical carcinogens through drinking water is much greater than that by the non-carcinogenic substances, and the order of risk scales for all pollutants is As>Pb >Fluoride>Nitrate>Mn >Fe>NH3-N. The research results can provide technical support for the water quality management of Erhe drinking water source region.
