The characterization of trihalomethane (THM) precursors and their eventual removal from water are elusive goals. Conflicting and highly variable results exist. Precursors of THMs were examined by sampling humic substances from three regions in Massachusetts with dissimilar geographic and geomorphic natures. Fulvic acid fractions from soil and water were analyzed for carbon and then chlorinated to produce THMs. Microwave emission detection showed little variation in THM production between sources but revealed differences between low and high molecular weight fractions. More dense chloroform fractions tended to contain greater amounts of carbon, suggesting that their removal will achieve the greatest THM reduction. Includes 14 references, tables, figures.
