The sources of halogenated hydrocarbons in the Passaic River basin have been investigated from several viewpoints. The distribution and concentration of both low and high boiling halogenated hydrocarbons and halogenated pesticides were determined in the following surveys: general stream survey; sewage treatment plant effluent survey; industrial waste treatment plant effluent survey; source, finished and delivered drinking water survey. This extensive portion of the survey - monitoring effort was performed through the grant period. Intensive sampling programs centered around the variation of halogenated material contained in both raw and finished drinking water processed at the Passaic Valley Treatment Plant, located in Little Falls, New Jersey. Several intensive studies were conducted using short and long sampling frequencies. It was observed that resulting halogenated hydrocarbon concentrations varied to a greater extent when a smaller sampling period was employed. Additional investigations of the trihalomethane formation potential and rate of trihalomethane production for stream samples were performed.
