This method has been designed primarily to detect the impact of toxic substances on the distribution of certain species of macroalgae (seaweeds belonging to the group known as 'wracks', and principally members of the genus 'Fucus''). This method monitors the upstream limit of
Benthic invertebrate communities are good indicators of organic pollution and are also sensitive to toxic pollutants. They are ideally suited to biological monitoring as they are sedentary and either feed upon sediment dwelling animals or the sediment .
Seagrass beds provide habitats for fish, prawns and other invertebrates and provide seafloor stability and are found in the littoral and sub-littoral zones along the coast and estuaries.
The Final Recommendations on Environmental Standards following phase 3 of the review have been published (November 2013). This report includes zinc standards.
Following a consultation that ended on 28th February 2013, UKTAG has finalised its recommendations on 1) biological standards for rivers, lakes, coastal and estuaries and 2) phosphorus standards for rivers.
The UK Technical Advisory Group (UKTAG) has commissioned a programme of work to derive Environmental Quality Standards (EQSs) for substances falling under Annex VIII of the Water Framework Directive (WFD).
A technical report on proposals for a first set of standards and conditions was published for review in 2006. The revised report was issued in August 2006 in the form of a recommendation to the UK governments. The UKTAG updated the report in November 2007.
This is a technical report that presents the first set of environmental standards and conditions proposed by the UKTAG to underpin the implementation of the Directive. Our report outlines the background to our proposals and describes the role they could play.
Operational monitoring will be undertaken in water bodies identified as ‘at risk’ or ‘probably at risk’ of not achieving good status (i.e. 1a and 1b water bodies).
The paper sets out UKTAG’s guidance on Coastal & Transitional Waters typology as required under Article 5 of the Directive. It identifies the methodology adopted in the UK and the Republic of Ireland and the results for the UK.
