云南省土壤污染重点监管单位地下水污染风险排查的问题分类及启示

Problem Classificationand Insights of Groundwater PollutionRisk Investigation for Key Soil Pollution Supervision Unitsin Yunnan Provinc

土壤污染重点监管单位地下水污染风险是当前备受公众关注的生态环境问题之一,但我国目前尚无专门针对该类单位开展地下水污染风险排查的典型案例.本文以云南省为例,对全省已公布的5批次146家土壤污染重点监管单位开展地下水污染风险现场排查,并对危险废物贮存间、有毒有害物质储罐、一般固废堆存区、污染治理设施、渣场、尾矿库、生产区等存在的地下水污染风险进行分析总结.在此基础上针对性地提出加强地下水污染防治监管,完善地下水污染防控措施,加快地下水监测井建设,开展地下水水质超标溯源等方面的地下水污染风险防治对策建议.本文研究结果可为国内其他省份开展土壤污染重点监管单位地下水污染风险防治工作提供借鉴和参考.

The groundwater pollution risk associated with key soil pollution supervision units is one of the ecological environmental issues that has recently garnered significant public attention.However,China currently lacks typical cases specifically targeting investigating groundwater pollution risks in such units.Using Yunnan Province as an example,this study conducts on-site investigations of groundwater pollution risks in 146 key soil pollution supervision units across five batches announced in the province.The analysis summarizes the groundwater pollution risks associated with hazardous waste storage areas,toxic and dangerous substance storage tanks,general solid waste storage areas,pollution control facilities,slag heaps,tailings ponds,and production areas.Based on this analysis,the study proposes targeted groundwater pollution risk prevention and control strategies,including strengthening the supervision of groundwater pollution prevention,improving groundwater pollution control measures,accelerating the construction of groundwater monitoring wells,and tracing the sources of groundwater quality exceedances.The results of this study can provide references and guidance for other provinces in China to conduct groundwater pollution risk prevention and control in key soil pollution supervision units.
