Screening Of Priority Pollutants In Urban
Stormwater: Innovative Methodology

Abstract
The implementation of the Water Framework Directive (WFD) 2000/60/CE
requires Member States to gain a better understanding of priority pollutants
entering surfaces waters. All kinds of effluents as well as urban water
(wastewater and stormwater) are concerned. So, studies have put the light on
direct discharges of these substances to the aquatic environment, since hazardous
pollutants, listed or not in the WFD, could be released to a watercourse by
stormwater. Moreover, data about priority substances in urban stormwater are
scarce so far worldwide. Till now, monitoring of priority pollutants usually
referred to analyses carried out on bulk samples without any discrimination
between dissolved and particulate phases. This paper describes an innovative
methodology which allows not only the determination of contamination level in
both the dissolved and particulate phases of hazardous pollutants, but also all the
precautions that must be taken from sampling to analysis. In order to include
specific urban pollutants, the WFD list of 33 priority pollutants was scientifically
extended to 88 individual substances. All samples will be collected, and
monitored for these urban pollutants, by automatic samplers from three storm
drainage systems in Paris and its suburb, whose watershed land use differs.
Keywords: dissolved phase, particulate phase, priority pollutants, runoff, urban
catchments, water framework directive, wastewater.
