Trihalomethane formation potential in the surface and ground water near Jakuševec landfill (Croatia): Impact of dissolved organic matter molecular size

Influence of molecular size of dissolved organic mat-ter on trihalomethane formation potential of surface and ground water nearby Jakuševec landfill (main landfill of the city of Zagreb, capital of Croatia) was examined. Water samples from the borehole at the landfill, outside from it and from the Sava River nearby the landfill. It has been shown that of all raw water samples that from borehole at the landfill site had the highest content of organic matter (28 mg NPOC/L). The dissolved organic matter was frac-tionated by ultrafiltration to the selected molecular mass ranges (<10000, 10000-50000 and 50000-500000). Trihalomethane formation potential was calculated in the raw water samples and the selected molecular size fractions after chlorination with sodium hypochlorite, with respect to the concentration of dissolved organic matter at pH 7+/-0.2, temperature of 25+/-1 &ordm ; C and 168 hours reaction. Trihalomethane concentrations in aqueous solution were determined after extraction by gas chromatography/ elec-tron capture detection. After chlorination, chloroform was the dominant trihalomethane (>90%), followed by bro-modichloromethane and dibromochloromethane. Fifty to sixty per cent of total trihalomethanes were developed with-in 24 hours, and each molecular size fraction indicated trihalomethane formation potential.
