Informative note on progress with, and the status of, recent developments in river phytobenthos analysis methods and the classification tool (DARLEQ) for the third River Basin Planning Cycle.
UKTAG has sought views and comments on the scientific work that underpins the latest set of proposals for biological and environmental standards. The standards are designed for use in taking decisions under the Water Framework Directive (WFD).
This paper details the procedures for translating the definitions of good groundwater chemical status into an operational classification system.
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 how to determine the WFD class boundary values for the supporting element phosphorus in lakes.
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.

This method statement provides guidance on the use of the metal bioavailability assessment tool (M-BAT) for practitioners involved in monitoring, assessment and classification using the new EQSbioavailable that have been developed for a number of metals under the Water F
