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 stand alone 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:

  • providing a marker of the current state of the environment for the measurement and monitoring of future change
  • assessing the condition, health and productivity of soils and sediments for agricultural and ecosystem functions
  • identifying and quantifying human impact on the environment, indicating elevated concentrations of potential harmful elements
  • identifying new possible sources of mineral potential

Applications are relevant to both human and ecological health, land use planning and development, contaminated land legislation, soil fertility, agricultural development, and mineral exploration.

Data from this project are available under license by contacting the BGS Enquiries team.

BGS offers expertise in all aspects of baseline geochemistry, including sampling and data visualisation and interpretation, and the applications of surface geochemistry data to human and ecological health studies. In particular, 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 the expertise is available. Alternatively contact Bob Lister or Joanna Wragg for additional information.
