The goal of this research project is to assess the use of ozonation in pre-disinfection and the use of chloraminesin secondary disinfection as treatment alternatives for reducing chlorinated disinfection byproduct (DBP) formation in a small Quebecwater utility. The research comprises two steps. First, a portrait of the spatial and temporal occurrence ofTHMs and HAAs in the distribution system is drawn. Second, pilot studies and laboratory assays that simulatethe formation of THMs and HAAs in the distribution system are carried out. Pilot studies include variablealternatives of water treatment and disinfection, including ozone followed by slow sand filtration, chloraminesand/or chlorine. Includes 21 references, tables, figures.
