目的了解临安市农村自备井水水质卫生状况,为制定农村改水方案提供依据。方法对临安市16个行政村布点抽样和调查,结合送样进行分析。结果调查112口井,合格率为36.60%,饮用井水合格率为71.43%,浅井与深井合格率(28.40%与66.67%)差异有统计学意义(P<0.01)。消毒与未消毒井合格率(80.00%与32.35%)差异有统计学意义(P<0.01),周边有无污染源合格率(25.30%与68.97%)差异有统计学意义(P<0.01)。结论农村自备井水合格率不高,需要科学选址打井,普及饮水卫生知识,加强饮用井水监测。
Objective To understand the sanitary status of well water quality in rural areas of Lin’an City and provide the basis for formulating rural water diversion plan. Methods Sampling and investigation of 16 administrative villages in Lin’an City were carried out and analyzed in combination with samples sent. Results A total of 112 wells were surveyed with a pass rate of 36.60%, a well rate of drinking well of 71.43%, and a pass rate of 28.40% and 66.67% for shallow well and deep well (P <0.01). The pass rate of disinfection and non-disinfection wells was statistically significant (P <0.01). There was no significant difference between the qualified rate of contamination sources (25.30% and 68.97%) in surrounding areas (P <0.01). Conclusion The qualified rate of self-provided well water in rural areas is not high, which requires scientific selection of wells to popularize drinking water hygiene knowledge and strengthen the monitoring of drinking well water.
