The European Union (EU) Water Framework Directive (WFD) adopted in 2000 requires EU Member States to adapt and to strengthen their monitoring of aquatic ecosystems. New monitoring strategies and practices have to be designed to monitor all polluting substances discharged into the aquatic environment, including priority substances or emerging pollutants that might be present at low concentrations. This requirement implies adapting monitoring locations and density, and monitoring frequency. It might also imply adapting monitoring techniques by integrating alternative screening methods and emerging tools for monitoring water quality to complement existing monitoring.We present the results of five European case studies that explored the potential uses of screening methods and emerging tools for responding to the new monitoring challenges of the WFD under different hydrological and environmental conditions. Combining their technical characteristics with the practical needs identified by monitoring experts and water stakeholders, we identified potential applications and opportunities for operational and investigative monitoring. Advantages of these methods include rapid delivery of results on-site, low-cost and capacity to acquire a larger number of observations within a given (short) time frame. © 2010 Elsevier Ltd.

In numerous river basins, the implementation of the Water Framework Directive challenges the administrative authorization delivered for agricultural withdrawals. In such a context, farmers demand public subsidies for building water reservoirs filled in winter for summer use (substitution reservoirs) in order to compensate the water quota reduction and prevent drop in income. We here present a financial and economic assessment method for such projects and highlight how it is possible to support the decision in assessing profitability thresholds. This method combines classical project economic analysis and microeconomic modelling. It is implemented in the Boutonne River basin, where an 84% agricultural water quota reduction is planned. Our calculation shows that this quota reduction could lead to a drop of 3.2Msin agricultural income at the basin scale and creation of a 15.5 Mm3 water reservoir could offset the 19.6 Mm3 quota reduction. However, this creation of a water reservoir for irrigation is not feasible without state aid. Economical and financial criteria alone do not make it possible to decide on creating the reservoir, but they are usable for determining the impacts of public subsidize rates.
