Abstract: This report describes the geological and lithological conditions in the
Newark area, and the occurrence, quantity, and quality of the available
ground-water supply. Newark is located on the Fall Line, the boundary
between the rolling hills of the Piedmont on the north and the gentle slopes
of the Coastal Plain on the south. Because the Piedmont is underlain by
dense crystalline rocks and their weathered clayey soils, which are of low
water-bearing capacity in contrast to the more permeable silts and sands
of the Coastal Plain, the exploration for ground water was confined to the
Coastal Plain south and southeast of Newark.
Description: The section on surface water resources was prepared under the supervision
of. Floyd F. LeFever, Surface Water Branch, U. S. Geological Survey.
The section on flow duration studies and figures 15-18 were done by Robert
O. R. Martin, hydraulic engineer, U. S. Geological Survey.
