The borehole penetrates the Seaford Chalk Formation and the underlying Lewes Nodular Chalk Formation.
The site is located on the side of a small east-north-east trending dry valley just above where it joins the main dry valley. The ephemeral head of the River Anton is in Penton Grafton (SU 329 472), 2 km to the south-south-east at an elevation of about 73 m above OD. This is similar to the minimum water level (73.6 m AOD) recorded in the borehole.
The diameter of the borehole is unknown. There is probably some casing in the top of the borehole.
This site replaced a 35 m deep well and borehole nearby (SU 3215 4875) in 1976, this is located within a dry valley at a 9.62 m lower elevation.
The Chalk is unconfined and the hydrograph has an annual sinusoidal appearance with additional peaks in some years.
