DISCLAIMER: In some locations, isolated intervals of principal and coarse aquifer materials separate
from the main extent of the interpreted principal aquifer materials may be present in the subsurface
that are not listed in the .kmz file attribute table. To determine if separate principal aquifer material
features are present at a location of interest, it is recommended that the user examines the interpreted
geologic cross sections provided in the associated files included with the .kmz at the specific location.
In some isolated locations, the interpolated 1995 CSD water table is above the ground elevation listing
in the attributes. This is an artifact of gridding a statewide, regionally-contoured water level surface that
does not have the resolution to account for local variations in topography, particularly in lowland areas
and in deeply incised valleys.
