Notes:- 1) All depths in metres, below existing ground surface at time of investigation
2) Borehole BH2, effective “TC” auger refusal on boulder at termination depth.

 

 

§.1 Groundwater

Groundwater was only observed in borehole BH1 at a depth of 4.1m. The drilling methods
used (water circulation) prevented the observation of groundwater below the open hole

auger drilled sections in BH3.

The groundwater level is expected to fluctuate with climatic conditions and may show a
damped response to tidal variations due to the close proximity of the site to the beach.
Seepage should be expected through the upper granular material following periods of
prolonged rainfall. However, typically the standing groundwater level is expected to be at
about RL 0.5m with fluctuations of +0.5m under normal (non-flood) conditions.
