Hydrogeological setting

This well measures water level in the North Downs Chalk. It penetrates the Newhaven and Seaford Chalk Formation, Lewes Nodular Chalk Formation and New Pit Chalk Formation.

Well or borehole construction

This is a dug well, which is 50.6 metres deep and was constructed before 1877 in the garden of the Well House Inn Pub. Monitoring has been carried out here since 1942.

A purpose built observation borehole was constructed 50 metres away (TQ 2584 5528) in 1999, but this original well is still used for long term monitoring, and it is this data that are held on the archive.

Hydrograph response

The water level in the well normally exhibits a 10 metre annual fluctuation, a relatively stable maxima develops in many years at around 30 metres below ground level, hinting at some degree of structual control, possibly a zone of enhanced porosity. The annual sinuosity is superimposed on a longer period response to significant drought episodes, typical of relatively poorly drained chalk blocks.

Data issues

Monthly data held until mid 2006 then weekly data. Added as an Index Well in 2006.
