1991—1998年湖北省农村饮水水质分析

目的：了解湖北省农村用水水质动态，方法：1991－1998年对全省6个县共71个供水点水质进行了监测和评价。结果：1991－1998年湖北省农村集中式供水单位水样合格率为46．4％－73．5％，分散式供水水样合格率为27．3％－56．5％，均无明显升高或下降趋势；集中式供水地面水源水样合格率高于地下水源（P＜0．05），地下水源合格率集中式供水与分布式供水无明显差异（P＞05），影响农村供水水质的主要因素是细菌学指标。结论：加强农村改水工程建成后的卫生管理是提高农村供水水质的关键，在条件相对较差的农村未改水地区，采用分散式地下供水仍是饮水改良的一种较好形式。

Analysis of Drinking Water in Rural areas of Hubei province (1991-1998)

Objective To monitor the quality of drinking water in rural areas of Hubei province. Methods From 1991 to 1998,monitoring and evaluation were done in 71 water supply sources in 6 counties. Result during this period,the qualitied rates of water samples are 46.4%-73.5% in rural centralized water supply sources,and 27.3%-56.5% in non centralized supply sources,the qualitied rate is higher in samples from centralized sources than the from underground source (P<0.05),what main factor for rural drinking water quality is the bacterium count. Conclusion strengthened hygiene control after completion of water supply projects is importance to improve quality of drinking water in rural areas.It is still a good method to improve drinking water by non-centralized water supply from underground sources in poor rural areas.
