Hydrogeological setting
No superficial deposits are mapped as being present at the site, but 2.4 m of clay and stones (till) were encountered when drilling. Beneath this the borehole passes through 42.1 m of Eyam Limestone Formation and 75.3 m of Monsal Dale Limestone Formation. The borehole ends in about 27 m of volcanic rocks.
The water is unconfined with a large seasonal range of about 25 m. The water level fluctuates between the Eyam and Monsal Dale limestones. The borehole is likely to be fully penetrating, as it is probable that the Litton Tuff and Cressbrook Dale Lava form an effective base to the aquifer.
Well or borehole construction
The length of lining tubes installed in the borehole is unknown.
Hydrograph response
The hydrograph overall has an annual sinusoidal appearance, but more than one peak can occur in a year due to responses to rainfall events.
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).
