This report provides estimates of ambient background concentrations (ABCs) for several metals and one metalloid in UK freshwaters.
The aquatic environment is sensitive to damage from a wide range of chemicals.
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 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.
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 report on the classification of surface waters is one of a series of reports by UKTAG to the UK administrations setting out UKTAG's recommendations and proposals on how waters should be classified for the purposes of the Water Framework Directive.
This paper describes the development of a typology for England, Wales and Scotland. It does not describe the rivers typology development for Northern Ireland, which is being undertaken by the North/South TAG for Ecoregion 17.
The paper sets out UKTAG’s guidance on the framework for the identification of, and assessments of ‘type-specific’ risk thresholds for deciding if a water body is likely to fail to achieve the ‘good status’ objectives in relation to existing biological classification schemes and monitoring data
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.
