In 2002/2003 several Dutch organizations cooperated in a screening program on theoccurrence and significance of pharmaceuticals in Dutch drinking water and drinking watersources. Out of a screening set of 105 pharmaceuticals, 44 pharmaceuticals were detected insurface water, 3 in groundwater and 9 in drinking water. The amounts of the pharmaceuticalsfound in drinking water were far below the health guidelines. A result of the project was amore focussed screening on pharmaceuticals, Endocrine Disrupting Compounds (EDCs) andother organic micropollutants by water companies and water research organizations.Because regular analysis of drinking water for all emerging substances is not possible, it isnecessary to predict the removal of the substances through the drinking water treatment plant.Research is carried out to obtain fundamental insight in the removal of organic micropollutants.Using the Quantitative Structure-Activity Relationships (QSAR), the behavior oforganic micro-pollutants in drinking water treatment processes can be modelled, taking intoaccount the design and operation of the process and varying influent quality parameters. As afirst step to develop QSARs the occurring pharmaceuticals and EDCs in the Dutch surfacewaters are classified and indicator compounds are chosen. An inventory of the relationbetween the indicator compounds and their removal by coagulation, ozonation and granularactivated carbon filtration is made. Includes 34 references, tables, figures.
