Bore 1 was drilled commencing 19th May 2008. Drilling was carried out using the rotary mud technique, the bore were installed as far into the forest as possible as the drill platform allowed. Drilling reached the watertable at ~10 m depth and bedrock at ~12 m depth. The drill hole was 200 mm diameter to 12m depth and then155 mm diameter to the bottom (14.2m). The casing used was UPVC PN12, 125 mm ID, from 0.30 m above ground to 14.2 m depth. Above ground the casing was enclosed in a steel tube (0.30m) with a lockable cap. The casing was slotted (1.2 mm) from 4.5 m to 14.2 m depth. There was no cap at the base (in rock). Filling: cement grout 0-2 m depth, drill cuttings 2-4 m depth, bentonite 4-4.5 m, gravel 4.5-12 m (rock), packer at 12m (top of rock), open hole 12-14.2 m. A water level logger was installed that logged data every 30 minutes during 2014.
