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).
