Figure E3 – Groundwater levels in a Chalk observation borehole (TG32/760) to the north of Stalham (TG 3701 2681). Note the gap in data during 2001 is observed in many hydrographs and is due to the Foot & Mouth outbreak which prevented monitoring in many places during the period March – autumn 2001.
