Sagami River is a representational river of Kanagawa Prefecture and the important source of drinking water. To survey the water pollution of Sagami River, 95 samples were collected by many citizens every 500 m right and left side alternately from Sagami Lake to Sagami Bay at Dec-1991 and Dec-1992. Chlorinated organic pollutants such as freon 113, Chloroform, 1,1,1-trichloroethane, tetrachloromethane, trichloroethylene and tetrachloroethylenein water were analyzed by GC-ECD using a head-space method. It was found that serious pollution (74700ppt) by trichloroethylene area existed 2km above the collection point for drinking water at Dec-1991. After this result reported by mass media preventive measures were carried out, and the trichloroethylene concentration at the point decreased remarkably at Dec-1992.
