摘　　要：目的 :了解深层地下水水质化学监测指标的本底值及相关关系。方法 :采集生活饮用深井水样 2 40份 ,按 GB5 75 0- 85《生活饮用水标准检验法》进行水质分析。结果 :在第四系深层地下水中 ,一般化学监测指标的本底值明显低于 GB5 749- 85《生活饮用水卫生标准》规定的限值 ,且枯水期各指标的含量高于丰水期 ;各指标间有一定的相关关系。结论 :本底值表明了深层地下水中的基础含量。监测值超过本底值或相关关系的改变 。Objective:To explore the background values of chemical monitoring indexes about the deep underground water quality and their correlativity.Methods:Analysis on 240 water samples collected from the deep well for drinking water,according to GB5750-85 Standard Examination Methods for Drinking Water.Results:The background values of general chemical monitoring indexes in deep underground water(the quaternary system) were obviously lower than the values limited by GB5749-85 Sanitary Standard for Drinking Water,and it was higher in low water period than in planty water period.There was correlativity between those indexes.Conclusions:The background values showed the basic contents in deep underground water.That the determined values exceed the background values or their correlativity was alternation should predict the occurrence of early pollution.
