淮河流域沙颍河段浅层地下水水质状况及污染特征

The Quality Condition and Pollution Characteristics of Shallow Groundwater in Huai River

众所周知,淮河流域地表水污染越来越严重,特别是沙颍河段(河南省域)污染最为严重,具有代表性,但地下水质污染情况不详。通过本次工作,采用地面调查、水土样化验分析等方法,系统的对淮河流域沙颍河段(河南省域)浅层地下水水质状况进行了调查分析评价。依据2003、2004年度环境水文地质调查及水质分析成果资料,对淮河流域沙颍河段(河南省域)浅层地下水质量现状、污染现状进行了评价;并对地下水污染特征进行了分析研究,发现了浅层地下水的面状污染特征、带状污染特征、垂向污染特征、居民地内外污染特征。对提高人民群众的饮水安全具有重要意义。

It is known that the pollution of the Huai river is more serious. However, the detailed groundwater pollution condition is not yet known, especially the Sha and Ying river （in Henan province）, which is the worst polluted and represents the water pollution in the Huai river. Ground investigation, water and soil analyses were adopted, which is the first time to investigate the quality of shallow groundwater. Based on the data of the investigation about environmental hydrological geology and the result of the water analysis in 2003 and 2004, the quality and pollution condition of shallow groundwater in Sha and Ying rivers have been evaluated. The pollution characteristics of groundwater has also been analyzed. The pollution characteristics for shallow groundwater is also discovered. It is also very important to improve the quality of drinking water for the people.
