Relevance of Trace Organic Substances in the Stormwater Runoff of Berlin

Rain water runoff is the largest untreated source of potentially high loads of trace organic substances discharged to urban surface waters.

The project OgRe aimed to support Berlin’s strategy related to the reduction of trace organic contaminants by describing a first set of locally important substances occurring in stormwater runoff, estimating the annual loads of trace substances which are discharged via stormwater runoff into the receiving waters and comparing them with relevant pollution loads originating from other entry paths.
