北京西郊砂石坑蓄洪工程场地环境质量现状评价

摘要

Through historical research data ,on-site inspection and monitoring ,and correlation analysis ,engineers evaluate the situation of the groundwater pollution in the study area ,find out the distribution of groundwater pollutant characteris-tics,distribution characteristics of pollutants in soil ,and relationship between groundwater and soil composition ,besides , analyze the sources of pollutants ,which provide key support for the western suburbs of Beijing gravel pit flood control pro -ject.%通过调查研究区历史资料、现场检测与监测、相关性分析等地下水污染现状评价，查明地下水中污染物的分布特征、土壤中污染物的分布特征，以及地下水和土壤之间的污染物组分关系，分析污染物的来源，其主要来自上游受到污染的地下水、填埋坑大气降水淋滤和现有西侧坑内地表水入渗，为“北京西郊砂石坑蓄洪工程”成功立项提供关键支撑。
