Abstract: This paper describes the performance of several types of water treatment plants in removing various molecular weight fractions of natural occurring aquatic organic matter, some of which functions as a precursor to trihalomethane formation. It was found that all plants studied preferentially removed molecular weight fractions of organic matter most reactive in forming THMs. The ability of water treatment plant to remove THM precursors is influenced by both process-related as well as source-related factors.
