A monitoring-based prioritisation methodology as part of the approach for the review of Water Framework Directive Priority Substances list

Abstract : Within the implementation of the Water Framework Directive (2000/60/EC, WFD), the European Commission shall review at least every four years the list of priority substances. In this context, an overall prioritisation process has been defined by the Commission and its Working Group E on Priority Substances, which takes into account as agreed by the text of the Directive "the selection of substances of concern undertaken in the relevant Community legislation regarding hazardous substances or relevant international agreements" but also results of a modelling-based approach as well as results of a monitoring-based approach. As regards the monitoring-based approach, a two-step data collection has been put into place so as to gather as exhaustively as possible monitoring data of chemical substances in European member states. Data have been collected from 26 Member States, Norway and Switzerland, gathering 14.6 million analyses in three different matrices (water, sediment and biota). A tiered algorithm based on risk assessment principles was elaborated to prioritise substances. A list of 38 substances and 2 families of substances was defined in this sense. A first review of the results permitted to detect a number of false-negative and eliminate unfairly selected substances from the first list. Finally, the proposed list includes 19 individual substances, polychlorobiphenyls and dioxins. This outcome will be taken into account in the overall prioritisation process to review the list of WFD priority substances by 13th January 2011. This work has been funded by EC DG Environment but does not represent the opinion of DG Environment or the European Commission services.
