This study monitored natural organic matter (NOM) characteristics of treated water samples in terms of dissolved organic carbon (DOC),UVA254, SUVA, XAD 8/4 resin fractionation, HPSEC-DOC/UV, 3D-fluorescence excitationand emission matrix (EEM). There are a number of underlying hypotheses that relate NOMproperties to treatability. First, chlorination disinfection byproducts (DBPs), coagulatability, and ozone reactivity generallycorrelate with a higher SUVA, the magnitude of the SEC-DOC humic substances peak, thedominance of the EEM humic-like spectral maximum, and a higher HPO fraction. Themagnitude of the SEC-DOC polysaccharide peak correlates with membrane fouling while themagnitude of the low MW acids peak inversely correlates with biostability. There is someevidence that haloacetic acid (HAA) precursors are more polar than trihalomethanes (THM)precursors and that lower SUVA and higher TPI and/or HPI fractions are more influential informing HAAs than THMs. The magnitude of the EEM protein-like spectral maximum can becorrelated with nitrogenous DBPs (N-DBPs; e.g., haloacetonitriles (HAAs). While Br- is theprimary determinant of bromate (BrO3-) formation, the character of NOM also plays a role, withhigher SUVA (HPO fraction) promoting BrO3- formation. Includes tables, figures.
