Title

Classification - 2008 River Cycle 1 phytobenthos water body level with confidence of class

Abstract

Survey results from 2007 showing the health of phytobenthos (algae that grows on rocks on the river bed, also known as diatoms) expressed against the Water Framework Directive status classes. This is for a national selection of English rivers. The dataset also contains statistical information on the confidence that the results have been correctly assigned to each status class, taking into account normal and naturally occurring errors associated with measuring the environment. The assessment method has since been improved. Attribution statement: © Environment Agency copyright and/or database right 2019. All rights reserved.

Quality and validity

Lineage

The Water Framework Directive classification system is risk based and focuses on where there is likely to be a problem. It uses a principle known as "one out, all out", which means the poorest individual results drive the overall classification for a water body. It reports on over 30 quality elements, grouped into ecological status and chemical status. Ecological status includes physico-chem (e.g. nutrients, pH, dissolved oxygen, ammonia) , biological elements (e.g. phytoplankton, macroalgae, fish, invertebrates) , specific pollutants (e.g. metals and compounds, organic compounds) , hydromorphology (e.g. depth, width, flow, structure). Chemical status is assessed using priority substances, priority hazardous substances and other pollutants that present a significant risk to the water environment.
