The site lies on the margin of the cover sand and a very small thickness of this deposit may be present above the Chalk. The borehole penetrates the New Pit Chalk Formation. The Chalk aquifer is unconfined at this site.
The borehole was drilled at 120 mm diameter. It is not recorded as having any casing, though there is likely to be at least a short section at the surface.
