These measurements are normally recorded on the paper well records.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Some boreholes may be selected for intensive monitoring, to build a detailed picture of groundwater behaviour. BGS hold data from national monitoring carried out prior to the 1970s. Since then, the UK&#8217;s monitoring networks have been run by the&nbsp;<a href=\"https:\/\/www.gov.uk\/government\/organisations\/environment-agency\" target=\"_blank\" rel=\"noreferrer noopener\">Environment Agency<\/a> and the&nbsp;<a href=\"http:\/\/www.sepa.org.uk\/\" target=\"_blank\" rel=\"noreferrer noopener\">Scottish Environment Protection Agency<\/a>, who hold their own data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">BGS operates several small-scale monitoring networks both as part of individual research projects and at our long-term environmental monitoring sites.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Contours of water table elevations in major aquifers have been drawn up for various aquifers as part of the production of hydrogeological maps and for research.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Digital information<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">BGS hold four distinct collections of digital water level data:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>digitised groundwater contours and model interpolations at regional and national scale<\/li>\n\n\n\n<li>measurements from borehole completion
