Web1:625 000. This generalised digital geological dataset is based on the published ‘poster’ maps of the UK from BGS. This dataset covers all of Great Britain and includes additional map data from Northern Ireland. It provides an excellent national overview of the UK’s geology and is commonly used as a teaching resource. WebThe groundwater productivity map indicates what borehole yields can reasonably be expected in different hydrogeological units. The ranges indicate the approximate interquartile range of the yield of boreholes that have been sited and drilled using appropriate techniques.

The BGS used cored boreholes to obtain profiles of the unsaturated zone pore water nitrate concentration as a function of depth in work pioneered in the 1970s. Nitrate contamination of groundwater has long been recognised as an important public health issue. short term finance limited
