Abstract

Haloacetonitriles (HANs) are a class of nitrogenous disinfection byproducts that can form during disinfection of water with chlorine or monochloramine. HANs have been shown to be more cytotoxic and genotoxic than their regulated counterparts, trihalomethanes and haloacetic acids. The goal of this project is to determine the sources and types of HAN precursors, identify precursor structures and formation pathways, and evaluate HAN degradation behavior in order to provide guidance to utilities on controlling HANs in drinking water and potable reuse systems.
