Abstract
UV absorbance at 254 nm is a good surrogate parameter for estimating the raw water concentrations of organic carbon (NPTOC--nonpurgeable total organic carbon) and THM precursors (TTHMFP--total trihalomethane formation potential). UV absorbance can be used to estimate the NPTOC and TTHMFP concentrations of raw waters, to monitor pilot-plant performance, and to monitor full-scale water treatment plant performance. It can also be measured rapidly, easily, and inexpensively.
