目的了解常州市农村生活饮用水水质卫生状况,保障人民饮水安全,为农村生活饮用水卫生监管提供科学依据。方法对常州所辖两市的2010~2011年农村生活饮用水水质检测结果进行统计学分析。结果 304份水样检测合格率为82.24%。2010、2011年水样检测合格率分别为88.82%、75.66%,差异有统计学意义(χ2=9.01,P﹤0.01);丰水期、枯水期水样检测合格率分别为94.08%、70.39%,差异有统计学意义(χ2=29.18,P﹤0.01);出厂水、末梢水水样检测合格率分别为82.89%、81.58%,差异无统计学意义(χ2=0.09,P﹥0.05)。结论常州市农村饮用水水质总体较好,但仍需改进。
Objective To understand the sanitary conditions of drinking water quality in rural areas of Changzhou, ensure people’s drinking water safety and provide a scientific basis for sanitary supervision of drinking water in rural areas. Methods A statistical analysis was made on the test results of drinking water quality in rural areas from 2010 to 2011 in the two cities under the jurisdiction of Changzhou. Results 304 samples of water samples pass rate of 82.24%. The passing rates of water samples in 2010 and 2011 were 88.82% and 75.66%, respectively, with significant differences (χ2 = 9.01, P <0.01). The passing rates of water samples in wet season and dry season were 94.08% and 70.39% The difference was statistically significant (χ2 = 29.18, P <0.01). The passing rates of water samples from the factory and peripheral water were 82.89% and 81.58% respectively, with no significant difference (χ2 = 0.09, P> 0.05). Conclusion The water quality of rural drinking water in Changzhou is generally good, but it still needs improvement.
