Abstract:

In May, 1982, as a condition for approval of plans for improvements to the Metropolitan District Commission (MDC) chlorination facility at Norumbega Reservoir, the Massachusetts Department of Environmental Quality Engineering (DEQE) required the MDC to perform a study and evaluation of its current disinfection practice. The intent of the DEQE request was to determine the effectiveness of disinfection by chloramines and to evaluate the impacts of increased chlorine dosage. The Metropolitan District Commission was also interested in the impact of increased chlorine dosage on trihalomethane formation and on tastes and odors in community distribution systems. The results of this study are presented and discussed.
