Hydrogeological setting
This borehole measures water level in the Anglian Chalk. It is drilled through 26 metres of Till deposits into the Burnham Chalk Formation.
Well or borehole construction
The borehole was drilled as an observation well, and consists of a 152 mm diameter, pvc lined borehole to 24.0 metres and 110 mm diameter hole to 101.47 metres.
Hydrograph response
This hydrograph has an annual sinusoidal pattern, with only a minor direct response to winter rainfall episodes. The annual variation is normally between 7 and 10 metres, with levels fluctuating around 17 m AOD.
During the 1990s levels were distinctly lower in the early and late parts of the decade. This may reflect pumping during this period.
Data issues
Adopted as an index well to replace Keelby Grange (TA11/158), which exhibited an almost identical response, apart from a slightly more pronounced peak at the highest levels, and a geater influence from the presumed pumping in the 1990s.
Borehole has been telemetered by the EA since 1997, with supplementary manual dips.
Acknowledgements
At a national level, groundwater level monitoring data is collected and managed by the Environment Agency (England), the Scottish Environmental Protection Agency, Natural Resources Wales and the Department of the Environment (Northern Ireland). Access to the data they collect (which includes many monitoring sites beyond those highlighted on these pages) and curate is online in England (DEFRA) and Scotland (SEPA).
