Occurrence of Volatile Chlorinated Organic Compounds and Alteration of Chlorinated Products in the Well Waters of the Tama River Basin

Abstract

The well waters (sampling number 127) of the Tama area in Kawasaki City were analyzed for volatile chlorinated organic substances, such as trihalomethanes (THMs).
Small amounts of chloroform, I, I, I-trichloroethane, carbon tetrachloride, trichloroethylene and tetrachloroethylene are found in the well waters.
I, I, I-trichloroethane, tetrachloroethylene, carbon tetrachloride and chloropicrin, besides THMs, may be produced by chlorination of the well waters.
It is showed that volatile chlorinated organic substances formation potential by chlorination significantly correlated with KMnO4 consumption of the well waters, that is, KMnO4 consumption : TTHMs and KMnO4 consumption : chloroform.
