Abstract

In determining the extent to which correlations exist among certain parameters (TOX, TTHM, TOC, UV absorbance, THM formation potential, and TOX formation potential), samples of raw water and treated water, including samples from the distribution systems, were collected from 12 full-scale systems in six states. The ratio of TTHM/TOX in surface waters treated by conventional coagulation, sedimentation, and filtration, at near neutral pH values (approximately 3:1), corresponds closely with the THMFP/TOXFP ratio in raw waters after a chlorine contact of 7 days at pH 7.
