Bromine Distribution Factors in THM Formation
Publication: Journal of Water Resources Planning and Management
Volume 120, Issue 1
Abstract
Trihalomethanes (THMs), a group of drinking water disinfection by‐products, are suspected carcinogens and are currently regulated by the U.S. Environmental Protection Agency. More stringent regulation of individual and total THM species is anticipated to meet the requirements of the 1986 Safe Drinking Water Act amendments. Because of this new focus on individual compounds, a set of statistical relationships called the bromine distribution factors were developed to characterize the impact of bromide ion on the distribution of THM formation potential (THMFP) species. A new derivation of these relationships is presented in this paper. Careful data analysis in combination with sound reasoning leads to a set of simultaneous equations that, when solved analytically, result in model coefficients that give both statistically sound and physically meaningful predictions for the distribution of THM compounds. Two independent data sets, including simulated distribution‐system THM data as well as THMFP data, were used to demonstrate the validity of the new formulation.
