Description
This article discusses the use of ultraviolet (UV) absorbance as a surrogate parameter for total organic carbon (TOC) and total trihalomethane (THM) formation potential. Two natural waters, both containing naturally occurring organic matter, were used in this study: the Grasse River and the Glenmore Reservoir. Testing was done on raw water samples; pilot plant studies took place at both sites; and existing full-scale plants at Canton, New York, and Oneida, New York were monitored. The study indicated that UV (254 nm) absorbance is a good surrogate parameter for nonpurgeable total organic carbon (NPTOC) 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 be measured rapidly, easily, and inexpensively. Includes 38 references, tables, figures.
