The Water Framework Directive (WFD) requires the "good status" for all water bodies by 2015 and the implementation of monitoring programmes to assess the quality of the water. In that purpose, an online monitoring station implemented on the Rhone river, downstream Lyon, comprises equipment for direct on-line measurement of parameters such as pH, temperature, dissolved oxygen, conductivity, turbidity, total organic carbon and nitrates, and indirect on-line estimation of priority substances listed in the WFD, in the range of pg/L. The added value of this approach, compared to the conventional one consisting in spot sampling and laboratory analyses, is to provide information on the quality of the water, on a real-time basis, allowing the detection of transient pollution events and compatibility with the spatial and temporal variability of the pollutants in the water bodies.

TheWater Framework Directive (WFD), adopted in 2000 by the European Community requires the good status for all water bodies by 2015. With the aim of assessing the water quality and the trends in this quality, an on-line monitoring station has been implemented on the Rhône river. Beyond the measurement of physicochemical parameters: pH, temperature, dissolved oxygen, conductivity, turbidity, total organic carbon and nitrates, this station detects, in a continuous mode and in the range of μg/L, the priority substances listed in the WFD, by means of spectrophotometric methods coupled to a SPE-like cartridge and by determination of the acute toxicity of the effluent. The first results confirm the good chemical status of the Rhône water. © 2010 Taylor & Francis Group, London.
