Description
Variability has been examined in the speciation and concentration of disinfection byproducts(DBPs) at two drinking water treatment plants in the United States. The twoplants treat surface waters with sufficiently different bromide concentrations to impactDBP speciation. Although both plants utilize chloramination as the terminal disinfectant,there is a significant difference between the brominated DBP distributions at the twosites. Comparative analysis has been conducted to evaluate this variability inconcentration and speciation of halogenated DBPs at the two sites, specifically for totaltrihalomethanes (THM4) and total haloacetic acids (HAA9).The differing DBP speciation is not currently accounted for through the quarterly DBPmonitoring program mandated by the U.S. Environmental Protection Agency. Although it is suspected that the healthrisks associated with individual DBP species vary, the current regulatory approach doesnot account for the speciation within each byproduct group. The results presented in thispaper explore the individual constituent concentrations at two utilities and show how theyvary in relation to the byproduct group summations, THM4 and HAA9.
