Summary In the so-called BIMAS PROJECT area of East Java investigations concerning Thiodan residues were made in the waters of the main waterway Brantas. The samples were taken from the water system towards the end of the main campaign of treatment with the insecticide Thiodan. Rivers, canals, fish ponds in the coastal area and sea water were analysed. It was found that on the average a low Thiodan content resulting from quick degradation of Thiodan existed in the flowing water system. In the fish ponds filled with water from the canal system, the residue values were almost below the detection limit (0.00003 ppm). The water of the Madura Sea contained insignificant residues in the top layer of fresh water near the river deltas. The sea water was free from Thiodan.
