Hydrogeological setting

The borehole measures water level in the Carboniferous Limestone of the Peak District.

It is drilled into the Hopedale Limestone Formation, Peak Limestone Group. A north–south trending fault mapped immediately to the east of the site upthrows the Woodale Limestone Formation.

The relatively deep water level in the borehole reflects a regional water level controlled by drainage in the incised valley of the River Dove to the south of the borehole.

Although not noted in the borehole log, the village of Alstonfield had several low yielding shallow wells that may have tapped perched aquifers.

Well or borehole construction

The well consists of a 178 mm diameter borehole to 121.92 metres, the diameter is reduced to 140 mm from 121.92 metres to 137.3 metres.

Hydrograph response

The well hydrograph shows an open groundwater system very responsive to seasonal recharge, and as might be expected from a limestone aquifer responses to rainfall can be rapid and peaky, responding to individual rainfall episodes through the winter.

Data issues

Weekly data until 1983, then monthly data.
