摘要
四川省东部红层区赋存的地下水是当地居民重要的饮用水来源。由于以往环境意识薄弱,区域乡镇广泛分布非正规垃圾填埋场,对地下水潜在污染风险大,威胁饮水安全。基于源-径-受体思想,选取9个评估因素,运用赋分法搭建地下水污染风险评价体系,对调研的川东红层区非正规垃圾填埋场地下水污染风险进行评估。结果显示:71.1%的填埋场已造成不同程度的地下水污染,26.7%的填埋场地下水污染风险等级较高。
The groundwater in the red bed area in eastern Sichuan Province was an important source of drinking water for local residents.Due to the weak environmental awareness in the past,informal landfill sites were widely distributed in regional towns,which had a great potential pollution risk to groundwater and threatened people's drinking water safety.Based on the idea of source-diameter-acceptor,nine evaluation factors were selected to establish the groundwater pollution risk evaluation system by using the assignment method,and the groundwater pollution risk of the informal landfill in the red-bed area of eastern Sichuan was evaluated.The results showed that 71.1%of the landfills had caused groundwater pollution to different degrees,and 26.7%of the landfills had higher groundwater pollution risk.
