BEDROCK GEOLOGIC MAPS OF NEW JERSEY
NEW STATE BEDROCK GEOLOGIC MAPS
FOR NEW JERSEY
The first state geologic maps since 1912 have been published
for New Jersey and are available to the public. The Bedrock
Geologic Map of Northern New Jersey, U.S. Geological Survey
Map I-2540-A (OUT-OF -PRINT) and The Bedrock Geologic Map of Central
and Southern New Jersey, U.S. Geological Survey Map I-2540-B
are available from the
and Publications or as GIS coverages and metadata as DGS 04-6.
Former Department of Environmental Protection Commissioner Bob Shinn
said, "This is one of the most detailed state geologic map in
the nation. It is invaluable for all ground-water contamination
and water supply projects, and for protecting aquifer recharge
areas and assisting land use planning and watershed initiatives.The
geology of the state is crucial because it serves as the basis
for other environmental maps, including characterization of watersheds,
ground water recharge, aquifers, radon and sink hole potential
as well as ecological habitat. The maps are also essential for
the evaluation of water supplies and the clean up of contaminated
A digital version of the
maps is now available on CD from Maps
and Publications for $30.00 or as a download as a Digital Data Series DGS04-6.
The bedrock maps were published under an agreement between the
Survey and the U.S. Geological Survey. The publications
include cross section maps of bedrock formations.
The cooperative mapping project began in 1984 to assess the
state's aquifers, using funding from the Water Supply Bond Act.
The first map was published in 1912 after many years of
laborious fieldwork, most of which was done on foot or horseback.
Over the past 85 years, many new geological concepts, thousands
of boring and wells, and other data have become available. Using
this data as a basis, geologists began a 10-year effort of detailed
field mapping to produce a map that was especially needed to protect
ground water for the most densely populated state in the USA.
Because of the detail (1 inch=1.6mi.), the new bedrock maps
have been printed in three, 41-inch by 57-inch sheets covering
northern, central and southern New Jersey. The previous map, which
has been out-of-print for many years, was at a much smaller scale
(1inch=4mi.) and lacked the detail provided in the new maps.
The full-color maps include accompanying text, plus a sheet
of cross sections showing the subsurfaceat the same scale.
The Bedrock Geologic Map of northern New Jersey is OUT-OF -PRINT. The Bedrock Geologic Maps of central and southern New
Jersey are sold together in one envelope for $25.
