3、le fraction)pollutants in surface and ground drinking water sources,(2)identification of the compounds,and(3)alerting analysts witha contaminant concentration prediction.This test methodfacilitates identification and quantification from 20 to 1000g/L of target contaminants,including:water-soluble fr
4、actionof aromatic compounds from the BTEX family(benzene,toluene,ethylbenzene,and xylenes)and naphthalene from thepolycyclic aromatic hydrocarbon(PAH)group,referred to asBTEXN in this test method,in water samples with up to 15mg/L of dissolved organic carbon(DOC).The main approachinvolves analyzing
5、and characterizing key water intake loca-tions before the treatment and developing the contaminantlibrary.The water-soluble(BTEXN)contaminants are associ-ated with,but not limited to petroleum oils and fuels includingcommercial diesel fuel,gasoline,kerosene,heavy oil,fuel oiland lubricate oil,etc.1.
6、2 The data sets are analyzed using multivariate methods totest contaminant identification and quantification.The multi-variate methods include classification and regression algo-rithms to analyze fluorescence EEM data acquired in thelaboratory.The common goal of these algorithms is to reducemultidim
