This is a Sniffer led project, the project funders were Scottish Environment Protection Agency, Environment Agency and Northern Ireland Environmental Agency, the work was done by APEM.
The assessment of compliance of surface waters with environmental quality standards (EQSs) for metals has to deal with a number of issues that do not apply to other substances.
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).
This report provides estimates of ambient background concentrations (ABCs) for several metals and one metalloid in UK freshwaters.
The environmental standards for lake levels were developed from work undertaken by SNIFFER project WFD48. A variation from the natural lake level regime has a number of ecological implications.These impacts include alterations to the underwater light climate and changes to the spatial distributio
The environmental standards for river flows were developed from work undertaken by SNIFFER profect WFD48 . The environmental standards were developed in order to assess the risk to ecological status posed by alterations in flows across the flow regime.
UKTAG requested Freshwater Task Team to develop acidification environmental standards based on new biological methods and additional evidence that has become available since the last round of standard setting in 2006.
In 2005, the Environment Agency performed an exercise on behalf of the UK Technical Advisory Group (UKTAG) to prioritise the Dangerous Substances Directive (DSD) 76/464/EEC Li
Following the publication of the first River Basin Management Plans and in response to queries about the differences in nitrate threshold values, the UKTAG Groundwater Task Team has re-evaluated the methodology for calculating threshold values.
