Experimental lycimeters investigating the vertical movement of heavy metals in the subsurface of a single UK site at Uffington, Berkshire.

Surface and borehole information for a nuclear waste site investigation programme at Altnabreac, Northern Scotland. Dataset includes geological mapping, surface geophysics, borehole information, borehole geophysics and spring survey geochemistry.

**Nothing Known About This**Grain size analysis and statistics of Jurassic-Cretaceous and Tertiary sands from East Dorset, the Hampshire Basin and Shaftesbury area. Analysis taken from selected sites therefore not complete cover of the area.

Data from projects that investigated the migration, transport and retardation processes of naturally occuring trace elements, as analogues the behaviour in the geosphere environment, of radionuclides from radioactive wastes. Study sites included: the Quaternary Broubster Peat Bog, near Thurso in Caithness (study of the migration behaviour and characteristics of U, Th, Ra, Pb, Cu, Zn, organic complexes such as fulvic and humic acids); the Needle's Eye site (Quaternary estuarine and marsh/mudflat sediments) on the Solway Coast of Dumfries and Galloway (study of the migration and retardation behaviour of U in Quaternary sediments and fractured Palaeozoic source rocks); Study of U geochemistry and transport behaviour from uranium-rich mine wastes at the South Terras Mine site, near St Austell, Cornwall; Study of the geochemistry of diffusion of Cl and I from marine source sediments into lacustrine sediments in Quaternary sediments from Loch Lomond. Data consists entirely of published reports of geological, geochemical, hydrochemical petrological and mineralogical information. The data includes descriptive and numerical data but is not digitally available in its present state.

Data related to contaminated land projects completed under commercial contract for local authorities (ConSEPT). The data held and used in the project included published BGS data (borehole, BGS Geology 50k and 10k, water well information), as well as third party data held on behalf of local authorities (including current and historical land use polygons and landfill sites) for the purposes of building the ConSEPT GIS. Consequently some data and the projects are strictly commercial in confidence and should not be shared.
