Groundwater Impacts — Monitor Wells have been
installed along the perimeter of the property and
have been measured to define a baseline for the
existing water table depth surrounding the
property. Groundwater modeling has also been
completed.
The model shows that impacts will not be greater
than an increase of 18 inches near the slurry wall
down to 6 inches on the west and south and side
of the property and a decrease of 18 inches near
the slurry wall down to 6 inches on the east side of
the property.
