Register of Selected Groundwater Observation Wells
The 'Register' provides a list of the observation boreholes and wells which provide contemporary groundwater level data for the National Groundwater Level Archive (NGLA). The sites were selected so as to give a reasonably representative cover for aquifers throughout England and Wales; there are very few sites in Scotland and Northern Ireland. The wells are grouped according to the aquifer to which the water level variations in the wells are attributed. A generalised list of aquifers provides the conventional names of the major UK aquifers; their major outcrop areas are shown on the map of principal aquifers and representative borehole locations.
Explanatory Notes
The six columns of the register are:
Well Number
The well numbering system is based upon the National Grid. Each 100 kilometre square is designated by prefix characters, e.g. SE, and is divided into 100 squares of 10 kilometre sides designated by numbers 00 (in the south-west corner) to 99 (in the north-east corner). Thus, the site SE94/5 is located in the 10 kilometre square SE94 while the number after the solidus denotes that the site is the fifth accessed in this square in the National Well Record Collection. A suffix such as A, B, etc., defines the particular well when there are several at the same site. For Northern Ireland, which is on the Irish Grid, the first of the prefix characters is always "I".
Grid Reference
The eight-figure references given in the Register relate to the 100 kilometre National (or Irish) Grid square designated by the two-letter code appearing as the prefix characters in the Well Number.
Site
The name by which the well is normally referenced. All the monitoring sites featured in the Register are shown on the map of Principal aquifers and representative borehole locations.
Measuring Authority
An abbreviation referencing the organisation responsible for measuring the groundwater level. A full list of codes, together with the corresponding names and addresses appears in the Directory of Measuring Authorities.
Records Commence
The first year for which records are held on the National Groundwater Level Archive.

Note: Since the original selection of boreholes for incorporation in the national network, a number of changes have been made to the list of selected wells. At some locations, observations could no longer be continued, and new sites have been added from time to time.
