Total Organic Halogen (TOX) and trihalomethanes (THMs) in tap water and other 22 indicators in raw water of 7 cities on the River Shinano were measured. Correlation coefficients between the tap water's TOX and the raw water's BOD, TOC or NH<SUB>4</SUB>-N were 0.857, 0.833 and 0.802, respectively. These results suggested that TOX in tap water is related closely to the contaminants in raw water which are produced from our human lives.<BR>Relationship between THMs formation and the retention time of tap water in a water distribution pipe system of a building was investigated. It was found that the amount of THMs increased with the retention time.
