The monitoring of groundwater levels is important for the management of groundwater resources. Within the United Kingdom a selection of observation boreholes are monitored for periodic assessment of the groundwater resources. The measurement of groundwater levels is undertaken principally by the water companies, the National Rivers Authority (NRA) for England and Wales, the River Purification Boards (RPB) for Scotland and the Department of the Environment (DoE) for Northern Ireland. Weekly and monthly data are supplied to the British Geological Survey (BGS) and these data are entered into an ORACLE database where they are assimulated with historical records. Additionally, paper copies are archived. Data usage is facilitated by a number of computer retrievals including well hydrographs in graphic form. Access to the groundwater level information is made available to the public at a small operational cost. A number of publications are produced giving a review on groundwater, including an assessment of recharge to major aquifers and also a number of hydrographs are illustrated from the key boreholes. The database has proved to be an invaluable tool in predicting environmental change, such as droughts and rising groundwater levels.
