The Water Framework Directive 60/2000/EG (WFD) requires Environmental Quality Standards (EQS) for polluting substances. Member States have to set objectives for individual surface water bodies (Article 4 WFD). The transitional period for Directive 2006/11/EC ended in 2013. Therefore, revision, adoption and implementation of the EQS for the substances on the "Indicative list of main pollutants" (see Annex VIII WFD) is needed to assess the status of the surface waters. In this context, the Federal Environmental Agency (UBA) initiated a project to update the environmental quality standards (EQS) for 10 pollutants (pollutants specific for river basin according to Ordinance on the Protection of Surface Waters (OGewV)) and to compile suggestions for environmental quality standards for 20 new chemicals. The searched data were documented data sheets according to the "Guidance Document No. 27: Technical Guidance for Deriving Environmental Quality Standards" (EC, 2011). The derivation of EQS for the matrices to be considered was performed in accordance with the rules as laid down in the "Guidance Document No. 27". Within this project EQS proposals were derived for the following 30 substances: 2.4-D, arsenic, bezafibrate, carbamazepin, carbendazim, chloroacetic acid, chromium, dibutyltin, dimethoate, dimoxystrobin, epichlorhydrin, erythromycin, flufenacet, flurtamone, imidacloprid, copper, metoprolol, monobutyltin cation, monolinuron, nicosulfuron, omethoate, triphenyl phosphate, phoxim, roxithromycin, sulcotrione, sulfamethoxazole, tetrabutyltin, triclosan, uranium, zinc.
