Groundwater Level Data (BGS)
The National Groundwater Level Archive held by the British Geological Survey records measurements of the depth below the ground surface of the water table, or its height above sea level across 181 sites in the UK.
Groundwater levels depend on aquifer properties, local geological conditions and a complex balance between recharge from rainfall, and discharges to rivers or pumped abstraction.
The data can be used to quantify resources, to understand the flow of groundwater and to measure the impacts of abstraction.
Available datasets -
Monthly updates of surface water flows and groundwater levels, with a hydrological report.
