惠州市某化工园区地下水污染调查与原因分析

Investigation and Cause Analysis of Groundwater Pollution in a Chemical Industry Park in Huizhou

为摸清化工园区地下水环境状况,实现生态环境可持续发展,以化工园区浅层地下水为重点,优化地下水环境监测网络,通过钻孔采样和监测分析,进行地下水环境状况调查评估,以此为化工园区地下水污染防治和风险管控提供借鉴。调查结果显示,该园区不存在地下水环境污染及环境风险情况,但地下水水质中挥发酚、氨氮、铁、锰等指标背景值超标,超标原因可能与填海造陆、海水入侵等地质环境因素有关。

Through the work of hydrogeological survey,shallow groundwater level monitoring,sampling of characteristic monitoring points,the environmental quality assessment of the shallow groundwater in the study area is analyzed. The results shows that there is no groundwater environmental pollution and environmental risk in the assessment object. The reason for volatile phenol,ammonia nitrogen,iron,manganese and other index background value exceeding the standard is that of the natural poor water quality caused by the geological environment,including seawater intrusion and land reclamation from sea. Finally,some rational recommendations have been given concerning the protection and risk control of groundwater resources in the chemical industrial park in order to promote the sustainable development.
