目的:了解北碚区农村饮用水卫生状况,为改善和提高农村饮用水质量提供依据,促进农村改水事业的发展。方法:按照国家标准于2008年-2011年枯水期(4月)、丰水期(7月)进行水样的采集、检验和评价。结果:2008年-2011年共检测水样300件,合格105件,合格率35.0%。其中,水质合格率2011年最高,2008年最低,丰水期高于枯水期,差异均有统计学意义(P≤0.05)。在各项检验指标中,微生物指标、感官指标和消毒指标不合格率高,毒理学指标全部合格。结论:近4年来,我区农村饮水安全工程在水源保护、工程设计与管理上都有了长足进步,但总体合格率偏低。各相关单位应完善农村饮用水的监督管理,注重人员培训,强化饮用水消毒工作,以保障农村生活饮用水安全。

Results: From 2008 to 2011, a total of 300 water samples were tested, of which 105 were qualified with a pass rate of 35.0%. Among them, the water quality pass rate in 2011 the highest, lowest in 2008, wet season is higher than the dry season, the differences were statistically significant (P≤0.05). In the test indicators, microbial indicators, sensory indicators and disinfection indicators failed, toxicological indicators of all qualified. Conclusion: In the recent 4 years, the rural drinking water safety project in our district has made great progress in water source protection, engineering design and management, but the overall pass rate is low. Relevant units should improve the supervision and management of rural drinking water, pay attention to personnel training, and strengthen the disinfection of drinking water to ensure the safety of rural drinking water.
