The test filter method was used to evaluate the waterworks relevant (non-biodegradable) and the drinking water relevant (non-biodegradable and non-adsorbable) organic substances in the River Rhine coming from the municipal sewage plants and the pulp industry in Germany. The results show that the test filter method is very suitable for the characterization of the different waste waters. An estimation based on the collected data shows that from 1987 to 1988 10% of the waterworks relevant AOX in the River Rhine has its source in municipal sewage water from Germany. In the same period about 30% was coming from the German pulp industry, but until today this value decreased strongly because the two most important pulp factories modified their bleachery. New investigations show that the dilution of the waste water in the River Rhine has to be taken into consideration.
