The Geochemical Baseline Survey of the Environment (G-BASE) is a major BGS project that has surveyed the surface geochemistry of the entire UK.
Soil and stream-sediment geochemistry data are now available for south-west England as a standalone dataset, and are accessible through the BGS digital data team. The G-BASE geochemical data has been coupled with the Tellus South West collaborative environmental survey and research project funded by the Natural Environment Research Council (NERC). A number of geochemical maps are available for download and to view.
Mapping baseline soil and stream-sediment geochemistry on a regional scale provides important chemical information that can be used for a number of purposes including:
These applications are relevant to both human and ecological health, planning and development, contaminated land legislation, agricultural development, and mineral exploration.
The BGS offers expertise in all aspects of baseline geochemistry, including bespoke sampling and data visualisation and interpretation, and the application of surface geochemistry data to human and ecological health studies. In particular, the BGS has expertise to provide underpinning geochemical interpretation of the relationships between the long history of metal mining in south-west England and a legacy of elevated concentrations of metals in river sediments and floodplain soils, especially with respect to current UK and European legislation.
Additional information on our expertise is available.
