摘要

LaiZhou domestic waste landfill is responsible for landfill domestic garbage of LaiZhou and surrounding towns. It has been put into operation more than 8 years. This investigation is focus on the landfill shallow groundwater quality status. According to hydrogeological conditions in the study area, emplaced 5 monitoring wells and 1 landfill leachate monitor point reasonably. Through analysis of 75 indicators of monitor , concluded that shallow groundwater of LaiZhou domestic waste landfill is polluted , especially Bromide and Benzopyrene which lead carcinogen to human indirectly is detected excessively in the diffusion of monitoring wells in the study area groundwater flow upsteam boundary monitoring wells and downstream 170m. The adverse impact can not be ignored to the local villagers.%莱州市生活垃圾填埋场承担着莱州市及周边乡镇生活垃圾的填埋处理，已投入运营8年多，填埋场浅层地下水水质状况是调查研究的重点。依据研究区水文地质条件，合理布设5个监测井点位和1个垃圾渗滤液点位，通过75项监测指标分析，莱州市生活垃圾填埋场浅层地下水出现了污染，特别是溴离子和苯并( a)芘2种间接导致人体致癌的物质在研究区地下水流场上游厂界的背景监测井和下游170 m的扩散监测井检出超标，给当地周围村民造成了不可忽视的不利影响。
