The prioritisation process ranks substances based on their potential exposure in the aquatic environment and hazard to aquatic life.
This report presents a proposal for a set of revised phosphorus standards for protecting High and Good status under the Water Framework Directive.
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.
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'.
Groundwater dependent terrestrial ecosystems (GWDTE) are wetlands which critically depend on groundwater flows and /or chemistries.
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.
This note recommends what we should do about the Freshwater Fish Directive (FWF), the Shellfish Directive (SWD) and the Dangerous substances Directive (DSD) which will disappear on 22 December 2013 as part of the Water Framework Directive.
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.
