<p>through the ground in various areas at various depths, to get a better understanding of the sites geology. Boreholes must be spaced properly from one another and drilled deep enough to provide accurate information for the geological model. Samples from the borehole are investigated and factors such as rock type, degree of weathering, and types of discontinuities are all recorded.</p>
