This national digital GIS product produced by the British Geological Survey indicates the potential for leakage to have a negative effect on ground stability. It is largely derived from the digital geological map and expert knowledge. The GIS dataset contains seven fields. The first field is a summary map that gives an overview of where leakage may affect ground stability. The other six fields indicate the properties of the ground with respect to the extent to which hazards associated with soluble rocks, landslides, compressible ground, collapsible ground, swelling clays and running sands will be increased due to leakage. The data is useful to asset managers in water companies, local authorities and utility companies who would like to understand where. and to what extent, leaking underground pipes or other structures may initate or worsen ground stability.

This dataset is derived from six GIS products including GeoSure soluble rocks, landslide hazards, compressible ground, collapsible ground, swelling clays and running sands. These are products in their own right, and are derived from the 1:50000 scale Digital Geological Map (DiGMap-50) and other data. DiGMap-50 is a product of geological maps surveyed since 1835. To create the Affects of leakage on ground stability Map, all the above datasets were given new attributes and some of the original attributes were combined. The summary map was created by combining data from all of the individual datasets. The dataset has been checked and approved by BGS.
