Surveillance monitoring has to be performed in a sufficient number of surface water bodies to provide an assessment of the overall surface water status within each... 

It is recommended to consider available monitoring data which has to be reported according to other European Directives, international river and seas conventions (e.g., 76/464/EWG, Nitrates Directive 91/676/EEC, OSPAR JAMP) for the purpose of surveillance monitoring where appropriate. 

The criteria for selecting sampling points for the surveillance monitoring are given in WFD Annex V 1.3.1. Water bodies probably at risk, probably not at risk and not at risk of failing the environmental objectives should be covered adequately. 

It is recommended to establish surveillance monitoring sites with fixed monitoring stations and automatic samplers allowing the collection of mixed samples. If not available, spot samples should be collected. Water level and flow should be recorded, as well as pH, conductivity and temperature. 

In case of transboundary waters, consultations about the proposed water body and surveillance monitoring sites should be held between the Member States involved. 

Representative approaches related to diffuse and widespread sources are often relevant in surveillance monitoring. In such cases, a sufficient number of monitoring points must be sampled within a selection of water bodies in order to assess the magnitude and impact of the pressures. 

Where surveillance monitoring indicates that the objectives set under Article 4 for a water body are not likely to be achieved and operational monitoring has not yet...
