This study monitored disinfection byproduct (DBP) concentrations in Philadelphia's finished waters to determine how they change as treated water is stored in, and travels through the distribution system. To date, most DBP research in the United States has focussed on treatment plant processes and concentrations of DBPs in water as it leaves the plant. Models have been developed to predict plant effluent DBP levels for a given set of influent water quality data, WTP process configurations, and chemical dosage parameters. Much less distribution system DBP data are available, and attempts to extend DBP formation models into the distribution system have had limited success. Most large data sets for distribution system DBPs are related to compliance trihalomethane (THM) measurements. Prior to this study, information about DBPs in Philadelphia's distribution system was limited to THM data. This study investigated the influence of detention time on DBP concentrations in the distribution system by sampling at plant effluents; at locations characteristic of short, medium, and long residence times; and at tanks, reservoirs, and suspected dead-ends. Water quality parameters and disinfectant residual levels were measured on all samples to examine their effects. The study design did not consider infrastructure materials and conditions. Includes tables.
