Abstract

After the implementation of the Water Framework Directive (WFD), there is an increasing need to monitor pollutant concentrations entering surfaces waters. This concerns all kinds of effluents, as well as urban waters (i.e., wastewater and stormwater). This study provides the first database on the occurrence of 88 individual substances in urban water and highlights direct discharges of these substances to the aquatic environment. Indeed, these hazardous pollutants, listed or not in the WFD, could be released without any treatment to watercourses during a storm. Keywords: dissolved phase, particulate phase, priority pollutants, occurrence, wastewater, stormwater, urban catchments, water framework directive. 1 Introduction Assessing concentrations of contaminants in domestic and industrial effluents has become an integral part of risk assessment and environmental regulation. Within this diverse research area there have been many works in the past on metals (Garnaud [1] and Gromaire-Mertz et al. [2]) and persistent organic chemicals, such as PAH (Gasperi et al. [3], Rocher et al. [4] and Grynkiewicz et al. [5]) and PCB (Chevreuil et al. [6]). More recently (Rule et al. [7, 8]), interest has been shown in priority pollutants of the Water Framework Directive (2000/60/CE), whose main objective is to achieve a \“good status” for all the
