On the depth of the Barton Lane borehole, groundwater level and aquifers, this graphic borehole shows the borehole extending down to 5.4 m and that it penetrates approximately to the bottom of the Gravel aquifer. The borehole stops around the top of the Forest Marble clay & mudstone, with the top of the Great Oolite Limestone aquifer almost 12 metres below ground level. A borehole was drilled on the Bathurst Estate in 1871-72, which found that it had to penetrate to almost 28 m before significant groundwater was encountered in the Great Oolite Limestone aquifer. So, this means that there is no direct connection with the Great Oolite Limestone aquifer in the Barton Lane Allotment borehole.
This does means that the July groundwater depth measurement in the Barton Lane borehole was only 1.9 m above the bottom of the borehole.

Comment: When flow in the River Churn is below the trigger value (32 million litres per day) at this point Thames Water must stop abstraction from the Baunton groundwater source, unless there is an emergency. This latter ‘an emergency’ requiring an abstraction permission almost happended in September 2022 after the hot dry summer … but wasn’t necessary see: Click here Drought Permit
