This poster paper presents a study to better identify and quantify chloramine decay mechanisms and their relationship tosupporting nitrification in distribution systems. This objective will be obtained using the CDWQ distribution system water quality model, field datacollected from participating utilities, and data gathered from laboratory pilot studies.Chloramines participate in numerous reactions that diminish residual concentrations during distribution while releasingammonia in the distribution system, supporting nitrification. A reaction model for free chlorine and chloramines was developed as part of adistribution-system water-quality model, called the Comprehensive Disinfection and Water Quality (CDWQ) model. CDWQ was calibrated usingdata from a year-long distribution system sampling program conducted at United Water of New Jersey (Woolschlager 2000; Woolschlager et al., 2001). Includes figures.
