摘要
通过对荆州市6个县(市、区)农村饮水随机抽样调查,结果表明,测定水样中除总硬度和浊度全部符合国家饮水标准GB5749-2006外,其他指标均有超标现象。地下水水质最差,且与自来水差异显著,与地表水差异极显著,自来水与地表水虽无明显差异,但总体水质优于后者。已建的集中供水工程水质不达标现象仍然严重,特别是以地表水为水源的自来水水质改善不明显,农村饮水安全形势十分严峻。
Random samples of 6 counties＇ drinking water in Jingzhou was tested;the results showed that,the indicators of all the samples exceeded the standard of regular indices in Drinking Water Quality（GB 5749-2006） except for hardness and turbidity.Underground water was the worst,as it was significantly different from tap water,and very significantly different from surface water.There was no distinct difference between tap water and surface water,but the quality of the former was better than the later in the mass.It was indicated that substandard water quality of the centralized water supply project remained serious,especially the part came from surface water,and safety situation of drinking water in Jingzhou rural was grim.
