摘要本文在对本市地下水监测数据的基础上，采用水质综合评价法和水质开发利用功能法评价了地下水污染现状，并在此基础上探讨了地下水污染预防措施与对策，得出主要结论有：地下水评价结果为优良的有1眼井，占监测井数的10%；评价结果为较差的有1眼井，占监测井数的10%；评价结果为极差的共8眼井，占监测井数的80%。符合饮用水标准的井仅占10%，大部分井符合农田灌溉水质标准。地下水污染整体比较严重，已经不适合作为饮用水水源。主要的污染因子为Hg、NO3-、NO2-和Mn。针对评价结果，提出来地下水污染防治措施建议，为遏制地下水污染趋势，改善地下水环境质量提供参考依据。关键词：地下水污染水质评价地下水污染预警污染防治1AbstractBasedonthegroundwatermonitoringdatainthecity,onthebasisofthecomprehensiveevaluationmethodofwaterqualityandwaterqualityevaluationmethodforthedevelopmentandutilizationoffunctionofthecurrentsituationofgroundwaterpollution,onthebasisofgroundwaterpollutionpreventionmeasuresandcountermeasuresarediscussed,themainconclusionsare:groundwaterevaluationresultforthefinewellin1eye,accountingfor10%ofthemonitoringwellnumber;Theevaluationresultsforthepoorhave1Wells,accountingfor10%ofthemonitoringwellnumber;Theevaluationresultsforthepoor,atotalof8Wells,accountingfor80%ofthemonitoringwellnumber.Uptothestandardofdrinkingwaterwellaccountedforonly10%,mostofthewellirrigationwaterqualitystandards.Groundwaterpollutionismoreseriouswhole,isnotsuitablefordrinkingwatersources.ThemainpollutionfactorforHg,NO3-andNO2-andMn.Accordingtotheevaluationresults,bringupgroundwaterpollutionpreventionandcontrolmeasuressuggested,tocurbtrendofgroundwaterpollution,improvethequalityofgroundwaterenvironment,provideareferencebasis.Keywords:waterqualityevaluationofthegroundwater.pollutionearlywarning.pollutionprevention.controlofgroundwaterpollution.2目录1引言..................................................................51.1研究背景............................................................51.2地下水污染概念......................................................51.3地下水污染源特征....................................................61.4地下水污染的途径....................................................61.5国内外研究现状......................................................71.5.1地下水质量评价研究历程............................................71.5.2地下水污染预警....................................................82水质监测.............................................................92.1地下水监测点网设计.................................................102.1.1监测点网布设原则.................................................102.1.2监测点网布设要求................................................102.1.3监测点（监测井）设置方法.........................................112.2地下水样品的采集...................................................122.2.1确定采样频次和采样时间的原则：..................................122.2.2采样频次和采样时间...............................................122.2.3采样技术、分析方法及质量控制.....................................123地下水水质评价.......................................................123.1评价指标的选取与评价方法...........................................133.2评价标准...........................................................133.3地下水污染综合评价.................................................143.4水质功能评价.......................................................154结论与建议...........................
