The European Water Framework Directive (WFD, 2000) provides the framework for the protection of ground- and surface waters whereby the different member states involved have to follow a tight time schedule to reach good ecological status for all water bodies. In 2002 the Water Directors endorsed a document called ‘Towards a guidance on establishment of the Intercalibration network and on the process of the Intercalibration exercise’ (Intercalibration Guidance). This intercalibration process is aimed at consistency and comparability of the classification results of the monitoring systems operated by each Member State for the different biological quality elements. The needs for the intercalibration exercise are given and some solutions are suggested.
