摘要
廊坊市地处京津之间,地理位置优越,地下水是其重要供水水源。为掌握其浅层地下水的水质现状及污染特征,对2005—2010年浅层地下水水质监测数据进行了分析评价。结果表明:主要污染因子有总硬度、溶解性总固体、氟化物(F)、氯化物(Cl)、铁(Fe)、锰(Mn),新增污染物为砷(As)、硫酸盐及硝酸盐;近五年来,北部地区浅层地下水水质总体有所改善,南部地区地下水污染趋势加重;地质因素和人为因素是导致廊坊市浅层地下水水质变化的主要原因;最后根据评价结果提出了相应的防治对策。
Located in the area between Beijing and Tianjin,Langfang possesses a preferable geographic location and its main water source is groundwater. To control the current water quality and polluted characteristics of shallow groundwater,it was analyzed and assessed the routine monitoring data on shallow groundwater quality for the period of 2006—2010. The results showed that the main pollutants were the total hardness,smelt total solid,fluoride,chloride,iron and manganese. New pollutants such as sulfate,arsenic and NO3-N were found in recent years. The shallow groundwater quality in the northern area was improved while in the southern area was worse. The main factors that affected shallow groundwater quality were human activities and geological origin. The prevention measures were proposed at last.
