摘　　要：为了弄清马鞍山市某疑似钢渣堆场对地下水产生的影响,以便为保护或治理该区域水环境提供依据,进行了地下水调查研究。结果表明,126万m3左右的填埋钢渣对地下水能够产生不同程度的污染,填埋区内第一含水层的地下水pH值较高,分布在11.41~12.24,显著高于对照点水样的pH值(7.87);总硬度指标显著高于对照点,对比《地下水质量标准》(GB/T 14848—2017),从pH值和总硬度看,水样属Ⅴ类水质;其他指标基本满足Ⅲ类及以上水质标准。第二含水层中的钢渣区地下水流向下游的监测井,因而pH值高于背景值;其他指标基本满足Ⅱ类及以上水质标准。In order to understand the influence of a suspected steel slag yard on groundwater in Maanshan city and provide basis on the protection or treatment of the regional water environment,the groundwater investigation was carried out.The results showed that about 1.26 million m3 of dumping steel slag can pollute groundwater to different degrees.The pH value of groundwater in the first aquifer in the landfill area is high,ranging from 11.41 to 12.24,which is significantly higher than that of the comparison point water sample(7.87).The total hardness index is significantly higher than the comparison point.Compared with the Groundwater Quality Standard(GB/T 14848—2017),the water sample belongs to Class V in terms of pH value and total hardness.The other indexes basically meet ClassⅢand above water quality standards.The groundwater in the steel slag area of the second aquifer flows to downstream monitoring wells,so the pH value is higher than the background value.The other indexes basically meet ClassⅡand above water quality standards.
