摘　　要：目的了解梅县地下水水质状况,为科学开发利用地下水提供依据。方法以2011年-2012年水质委托检验中水样种类为井水、山泉水的样品为研究对象,依据《生活饮用水标准检验方法》（GB/T5750-2006）进行水质检测和结果评价分析。结果 2011年-2012年梅县地下水的合格率为63.47%,井水、山泉水的合格率分别为60.10%和67.59%。在检测指标中,菌落总数、总大肠菌群、耐热大肠菌群、pH值合格率较低,分别为62.22%、55.00%、55.00%和75.28%,其余各项指标合格率均在90%~100%之间。结论梅县地下水质总体情况良好,微生物指标超标为生物性污染,应引起注意。Objective To investigate the groundwater quality in Meixian,and provide the basis for scientific development and utilization of groundwater.Methods The well water and mountain spring water samples from water entrusted inspection center in2011 2012 were taken as the research objects.According to ＂standard examination methods for drinking water＂（GB/T5750-2006）,water quality was analyzed and evaluated.Results The qualified rate of groundwater in Meixian in 2011-2012 was63.47%,the qualified rates of well water,spring water were 60.10% and 67.59%,respectively.The qualified rates of total bacteria,total coliforms,thermotolerant coliforms and pH were low,with 62.22%,55.00%,55.00% and 75.28%,respectively.The qualified rates of ohter indexes were between 90%~100%.Conclusion The groundwater quality was good in Meixian in general.The microbial indexes exceeding the standard was caused by biological pollution,which should be paid attention.
