水文地质勘查表明,亨寨地区不整合地层系统赋存3个含水层,因1号钡渣堆场渗漏,致使基岩风化裂隙水和孔隙水含水层中的地下水出现了S2-污染,16口水井不能饮用,岩溶含水层未发现S2-。建议以中等风化变余砂岩地层(K≤10-7cm/s)作为堆场的天然防渗层,采用注浆帷幕进行渗漏治理,地下水污染是能够控制的。
Hydrogeological surveys show that the unconformity stratigraphic system in Hengzhai area contains 3 aquifers that cause S2-pollution of groundwater in the bedrock fissure water and pore water aquifers due to the seepage of No. 1 barium slag yard. 16 Mouth water wells can not drink, karst aquifer did not find S2-. It is suggested that the medium weathered ametrine sandstone stratum (K≤10-7cm / s) should be used as the natural seepage prevention layer of the yard, and the grouting curtain should be used for seepage treatment. The groundwater pollution can be controlled.
