This layer of the map based index (GeoIndex) shows the location of waste sites within England and Wales. The information is taken from an index listing of some 3500 waste sites in England and Wales identified by BGS as part of a survey carried out on behalf of the Department of the Environment in 1973. The index has been corrected and updated to a limited extent, but the data itself has not been changed. The data was collected in 1972 and the information reflects the knowledge at that time. It does not reflect current interpretation. Not all authorities made returns and there are not records for all of the sites listed. However, the data is an invaluable source of information about pre-1974 sites. The records themselves contain interpretations of the geology, ground and surface water risk assessments and information about the quantities and types of waste. Data visible at all map scales.

This layer of the map based index (GeoIndex) shows the location and name of active mineral workings in the UK and is derived from the BGS BritPits (British Pits) database. The BritPits database of onshore mineral workings in the UK is based on the records of the BGS, the Coal Authority, industry sources and the Valuation Office Agency (Minerals) and is maintained by the BGS Onshore Minerals and Energy Resources Programme. The database describes individual workings, both currently active and formerly worked, in terms of name, location (including Mineral Planning Authority), ownership, basic geology, commodity produced and end-uses. Contact details including the operator name, address, postcode and telephone and fax numbers are held where known. The location of over 6000 workings are held, with about 2000 currently being worked. The data can be produced digitally, under licence, in formats to meet customer requirements, such as locations of workings or operator addresses, and is suitable for use in GIS applications using the British National Grid. Although the GeoIndex is updated at regular intervals more information may be available than is shown at any one time.
