Abstract :
The effects of pH and bromide ion concentration on the formation of nine haloacetic acids (HAAs) and total
organic halogens (TOX) in chlorinated drinking water have been evaluated. In an extensive study, the relationships
of nine HAAs with TOX have been investigated. Honesty Significant Differences test (HSD) and ANOVA tests were
used for the statistical analyses. The study determined the concentration range of nine HAAs as of a percentage of
TOX at varying experimental conditions. Statistical analyses showed that the parameters pH and Br had significant
effects on the formation of nine HAAs and TOX. This study also showed that brominated and mixed species of
HAAs would be dominant in the presence of high bromide ion concentration which contributes a high percentage
of the TOX. The results of this study could be used to set up a maximum contaminant level of TOX as a water
quality standard for chlorination by-products.
