Monitoring and classification

SEPA has introduced new water monitoring and classification systems that will provide the data to support the aim of the Water Framework Directive (WFD): that all water bodies are of good ecological status, or similar objective, by 2015.

SEPA has many years' experience in monitoring and protecting the aquatic environment. The WFD introduces a holistic approach to monitoring for a range of different pressures. The new monitoring network will enable us to identify further problems and resolve them, thereby improving the water environment.

The new classification system covers all rivers, lochs, transitional, coastal and groundwater bodies, and is based on a new ecological classification system with five quality classes. It has been devised following EU and UK guidance and is underpinned by a range of biological quality elements, supported by measurements of chemistry, hydrology (changes to levels and flows) and morphology (changes to the shape and function of water bodies). Some of the quality elements used in the new ecological classification system have not been monitored in Scotland before.

The classification scheme has been agreed across the UK, and gives us the best picture we have ever had of the quality of Scotland's aquatic environment.

Current classification information can be found in our web-based interactive map that has been developed for river basin management planning.

EU and UK work

SEPA has made a significant contribution to the EU and UK working groups directing the work on monitoring and classification. This work is taken forward through European CIS guidance and the UK Technical Advisory Group (UKTAG).
