目的了解宜宾市翠屏区“红层找水工程”农村生活饮用水卫生质量状况,为解决农村安全饮用水问题提供科学依据。方法对2007-2008年翠屏区修建的9 612口红层水井进行数量不少于3%的抽样检测,按照GB/T5750-2006《生活饮用水标准检验方法》进行检测,(GB5749-2006)《生活饮用水卫生标准》进行评价。结果共检测“红层找水工程”生活饮用水水样409份,合格率为19.3%,各项指标中合格率最低的是总大肠菌群,合格率仅为32.5%。各乡镇红层水井合格率差异有统计学意义(χ2=45.0,P﹤0.05),菜坝镇合格率最低。结论宜宾市翠屏区“红层找水工程”井水的水样合格率较低,水质较差,农村饮水安全问题十分突出,影响水质的主要因素是以微生物污染为主。
Objective To understand the health quality of drinking water in rural areas in Cuiping District, Yibin City, and to provide a scientific basis for solving the problem of safe drinking water in rural areas. Methods A sampling test of not less than 3% of the 9 612 reddish wells constructed in 2007-2008 in Cuiping District was conducted according to GB / T5750-2006 “Standard Test Method for Domestic Drinking Water” (GB5749-2006) Drinking water health standards “for evaluation. Results A total of 409 samples of drinking water from the red beds were collected and the pass rate was 19.3%. Among the indicators, the lowest pass rate was total coliforms, with a pass rate of only 32.5%. The qualified rate of red beds in each township was statistically significant (χ2 = 45.0, P <0.05), and the lowest in the villages of Caiba. Conclusion The qualified rate of water sample in well screen of ”red layer water finding project" in Yibin City is lower, and the water quality is worse. The problem of drinking water safety in rural areas is very prominent. The main factor affecting water quality is microbial contamination.
