摘　　要：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。Based on hydrogeological investigation, there are three aquifers in unconformable stratum of Hengzhai region. Because No. 1 barium slag dump seeps, it results in the groundwater in the aquifers of fissure water in zone of weathering and pore water contain S2- and the water of 16 wells is undrinkable, but S2- is not found in the karst aquifers. It is supposed with the application of moderately weathered metamorphic sandstone stratum（ K≤ 10^-7cm/s）as natural anti-seepage layer, the pollution of groundwater can be controlled by using grouting curtain as the leakage treatment.
