Suitability of Organic Matter Surrogates to Predict Trihalomethane Formation in Drinking Water Sources.

ABSTRACT: Broadly applicable disinfection by-product (DBP) precursor surrogate parameters could be leveraged at drinking water treatment plants (DWTPs) to curb formation of regulated DBPs, such as trihalomethanes (THMs). In this study, dissolved organic carbon (DOC), ultraviolet absorbance at 254 nm (UV₂₅₄), fluorescence excitation/emission wavelength pairs (I_Ex/Em), and the maximum fluorescence intensities (F_MAX) of components from parallel factor (PARAFAC) analysis were evaluated as total THM formation potential (TTHMFP) precursor surrogate parameters. A diverse set of source waters from eleven DWTPs located within watersheds underlain by six different soil orders were coagulated with alum at pH 6, 7, and 8, resulting in 44 sample waters.
