This layer of the Map based index (GeoIndex) shows where water wells exist with data available on transmissivity, storativity and discharge/drawdown. These parameters indicate the physical characteristics of the aquifer which can relate to factors such as possible storage capacities or rate of movement of water through the rock.

This layer of the map based index (GeoIndex) is a map based index of the National Well Record Archive. This index shows the location of water wells along with basic information such as well name, depth and date of drilling. The index is based on the collection of over 105,000 paper records of water wells, springs and water boreholes. Geological information, construction details, water quality data and hydrogeological data may also be available for some water wells. The amount of detail held on individual sites varies widely and certain fields will have an 'unknown' value where the paper records have yet to be checked for their content. The zero values for the depth represent those for which the depth has yet to be entered into the database from the paper records.

This layer of the Map based index (GeoIndex) shows the location of records of boreholes, shafts and wells from all forms of drilling and site investigation work. Some 850,000 records dating back over 200 years and ranging from one to several thousand metres deep. Currently some 50,000 new records are being added to the collection each year. The dataset available via the GeoIndex is a snapshot, taken at a particular date, of the Single Onshore Borehole Index. Although the GeoIndex is updated at regular intervals more information may be available than is shown.

This layer of the map based index (GeoIndex) shows sites where regularly monitored rest water level data are available, usually covering a long time period. The data shows seasonal fluctuations in the water table and responses to periods of high or low rainfall.

A collection of hydrogeological maps created by the British Geological Survey between 1967 and 1994. The maps in the collection cover aspects of groundwater availability, exploitation and quality, and were published at various scales from 1:25 000 to 1:625 000. A hydrogeological map is a specialized type of map that illustrates the distribution and characteristics of hydrogeological features in a particular area. Hydrogeological maps of the UK provide information on major aquifers, including geological and lithological information, surface drainage systems and water quality issues. The 23 maps show information on surface water features, the three dimensional geometry of aquifers, groundwater levels, abstractions and quality including saline intrusion in varying amounts of detail. They range in scale from 1:625 000, for the national map of the hydrogeology of England and Wales, down to 1:25 000 for some of the smaller regional maps. These maps are important tools for understanding and managing groundwater resources, as well as for addressing water-related environmental issues. These maps are hard-copy paper records stored in the National Geoscience Data Centre (NGDC), and are delivered as digital scans through the BGS website.

This sub-surface hydrology dataset complements 13 other datasets as part of a study that compared ancient settlement patterns with modern environmental conditions in the Jazira region of Syria. This study examined settlement distribution and density patterns over the past five millennia using archaeological survey reports and French 1930s 1:200,000 scale maps to locate and map archaeological sites. An archaeological site dataset was created and compared to and modelled with soil, geology, terrain (contour), surface and subsurface hydrology and normal and dry year precipitation pattern datasets; there are also three spreadsheet datasets providing 1963 precipitation and temperature readings collected at three locations in the region. The environmental datasets were created to account for ancient and modern population subsistence activities, which comprise barley and wheat farming and livestock grazing. These environmental datasets were subsequently modelled with the archaeological site dataset, as well as, land use and population density datasets for the Jazira region. Ancient trade routes were also mapped and factored into the model, and a comparison was made to ascertain if there was a correlation between ancient and modern settlement patterns and environmental conditions; the latter influencing subsistence activities. This dataset includes water quality index values for sub-surface hydrology and also maps surface and sub-surface irrigation zones in the Jazira region. Evidence suggests that wells have been dug over the millennia to extract potable groundwater for human and animal consumption. It is feasible that groundwater could also have been extracted to irrigate gardens and small fields?

Geochemistry (these are prepared on the basis of a large number of chemical analyzes of rocks, soil, streams- or lake sediments, streams- or lake water, peat and plant roots). Groundwater (provides access to data on wells and springs for purposes such as water supply, energy, research, monitoring of groundwater quality, level and temperature, reports on groundwater investigations and groundwater potential). marine geology (including sediments (grain size and formation), sedimentation environments, bottom conditions, pollution, and landscape and landforms). Minerals, including areas allocated for mineral permits at state owned ground. The data contains information on exploration and production rights and an overview of deposits of metals (ore), industrial minerals, and natural stone in Norway. Enginering geology (National database for ground investigations (NADAG) shows borehole (points) where ground surveys are carried out. NADAG includes geotechnical data (boreholes) and has a view service for this).
