NOTES:
a) All depths measured in metres below ground level at the time of the investigation.

No groundwater was encountered in any of the boreholes. However, seepage may occur along
the soil/rock interface during and after periods of wet weather.
In addition to the above, an Emerson Class test and a soil classification test were carried out to determine
the dispersivity and nature of the natural clay present on site for possible future use for a dam. The results of
this laboratory testing are provided in the table below.
