This paper details the procedures for translating the definitions of good groundwater chemical status into an operational classification system.
The Water Framework Directive (2000/60/EC) and Groundwater Daughter Directive (2006/118/EC) (GDD) require Member States to prevent inputs of hazardous substances into groundwater subject to various exemptions. The documents below set out the list of standards that can be used to assess inputs of hazardous substances into groundwater.
Please note that this guidance is for information only; it should not to be used in the classification of ecological status until information is available on which of the species listed are considered ‘high impact'.
This method statement describes a system for assessing and classifying rivers in relation to passage of migratory fish across barriers in Scotland.
The alarm list contains species thought to pose a risk to surface waters and their ecological status under the EC Water Framework Directive, but whose presence has not yet been recorded in Great Britain.
Phytobenthos are good indicators of nutrient enrichment and can be used to assess lake water quality. Diatoms are the main plant groups that we use because their silica cell walls make them easy to identify under the microscope.
