摘　　要：目的了解重庆市涪陵区"红层找水工程"农村生活饮用水的水质卫生状况。方法对2010-2014年涪陵地区修建的5 500口红层水井,进行数量不少于4%进行抽样检测,按照《生活饮用水标准检验方法》(GB/T5750-2006)进行检测,《生活饮用水卫生标准》(GB5749-2006)进行评价。结果共检测"红层找水工程"水样220份,一般化学指标中总硬度及锰的合格率分别为72.7%和71.0%、其它各项指标合格率均在90.0%以上;毒理指标合格率为95.0%以上;微生物指标的合格率相对较低,菌落总数的合格率为10.0%、总大肠菌群的检出合格率仅为5.45%。结论重庆市涪陵区"红层找水工程",农村居民的饮用井水的一般化学指标和毒理学指标的合格率均较高,只有微生物的合格率极低,提示在当地农村开展和普及饮用水健康知识教育,具有极其重要的意义。Objective To investigate rural drinking water quality ＂ red layer to find water project＂ in Fuling District of Chongqing. Methods Sampled 4% of 5500 lipstick layer wells built in Fuling District in 2010- 2014,testing according to ＂ drinking water standard test method＂（ GB / T5750- 2006）,evaluating according to ＂drinking water health standards＂（ GB5749- 2006）. Results 220 samples of ＂ red layer to find water project＂ Drinking water were detected. The rate of general chemical indicators of total hardness and manganese were 72. 7% and 71. 0% respectively,and other indicators qualified rate above 90%; 95% or more samples passed toxicological indicators; microbial indicators pass rate was the lowest with 10% of total bacterial count and 5. 45% of total coliform. Conclusion Except for the low microbial indicators pass rate,the general chemical indicators and toxicological indicators pass rate is high of resident drinking water in Fuling District of Chongqing ＂ red layer to find water project＂,and the drinking water health education should be strengthened in rural population to reduce excessive health hazards by microorganisms in drinking water.
