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.
This revised paper provides the detailed procedures for the translation of the definitions of good groundwater quantitative status outlined in Annex V of the WFD into an operational classification system.
This classification method enables the assessment of invertebrates in rivers in relation to general degradation, including organic pollution.
The purpose of this report is to derive EQS for the substance emamectin benzoate for sediment and for water (protective of pelagic organisms).
This method statement describes how to determine the WFD class for the lake fish biological element.
This classification method enables the assessment of fish in rivers according to the requirements of the Water Framework Directive (WFD). It encompasses fish abundance, taxonomic composition and age structure.
Further to the UKTAG Biological and Environmental Standards consultation May 2019, the working paper outlining impact classification of alien
UKTAG has sought views and comments on the scientific work that underpins proposals for fish classification. This classification is designed for use in taking decisions under the Water Framework Directive (WFD).
A method statement describing how to determine the WFD class boundary values for the supporting element nitrogen in lakes. Environmental standards for total nitrogen have been developed for implementation in the third river basin planning cycle.
Phytobenthos are good indicators of nutrient enrichment and other pressures, and can be used to assess river water quality. Diatoms are the main plant groups that we use because their silica shells are easy to identify under the microscope.
