甘肃某冶金废渣回收项目地下水资源及环境影响评价

Impact assessment of groundwater resources and environment on a metallurgical slag recovery project in Gansu

项目建设场地断裂构造不发育,地层出露有三叠系、新近系及第四系,地下水以第四系松散岩类孔隙水为主,主要分布在永宁河支流的西沟河河沟中部,靠近河沟地表水流的地段具有一定的富水性,地下水资源开发利用量小。本项目的建设对下游柳林镇、永宁镇乡镇集中供水水源地无影响,项目建设可以满足地下水环境质量标准的要求。

The fault structure of the project construction site is undeveloped.Triassic,Neogene,and Quaternary systems expose in the stratum.Groundwater is mainly composed of Quaternary loose-rock pore water,which is mainly distributed in the middle of the Xigou River Gully,a tributary of the Yongning River.The area near the surface of the river ditch has a certain amount of water richness,and the development and utilization of groundwater resources is small.The construction of this project had no impact on the centralized water supply sources of Liulin Town and Yongning Township in the downstream.The project construction can meet the requirements of groundwater environmental quality standards.
