摘　　要：某土壤污染状况调查项目中个别点位地下水pH值与重金属砷异常,但其他检测因子结果正常。通过现场补充资料收集、现场踏勘和对异常点位加密采样,得到结果:地下水pH异常是由地表水泥浆液汇聚及点位附近建筑垃圾堆放造成的,建井污染和洗井不充分导致了地下水重金属砷异常。研究结果对土壤污染状况调查中检测因子异常的原因探讨具有一定的借鉴意义。In a soil pollution investigation project,the value of pH and heavy metal arsenic of groundwater at individual points were abnormal,while the results of other detection factors were not.Through the collection of on-site supplementary data,on-site reconnaissance and intensified sampling of abnormal points,we found that the abnormality of pH of groundwater was caused by the convergence of cement slurry and stacked construction waste near the point.The pollution caused by well construction and insufficient well cleaning led to the abnormality of heavy metal arsenic in groundwater.The research results have certain reference significance for the discussion of the reasons for abnormal detection factors in soil pollution investigation projects.
