Ground Water Levels
The location of the ground water level is essential for deep excavation, water-logged areas. The existing wells in the nearby vicinity of the proposed site 'md bore holes should be used for recording the ground water table. The chemical analysis of ground water is also suggested for the determination of chemical constituents. If ground water is contaminated, the borings should be plugged. Borings through clay layers into granular subsoils which contain ground water table should also be plugged since this state represents a confined aquifer.
