A Manganese Bioavailability Tool has been developed that simplifies the integrated Biotic Ligand Model but runs in MS Excel. It requires data input for site-specific dissolved organic carbon, pH and calcium.
A Copper Bioavailability Tool has been developed that simplifies the integrated Biotic Ligand Model but runs in MS Excel.
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
This paper sets out guidance on the delineation and characterisation of groundwater bodies as required under Article 5 of the Water Framework Directive (WFD) and detailed in Annex II of the WFD.
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.
