Geophysics Geophysics GEOPHYSICAL METHODS CAPABILITIES The New York Water Science Center (NY WSC) makes extensive use of geophysical methods in its hydrologic investigations and research in cooperation with local, State, and Federal partners. The NY WSC staff has many years of experience in collecting and interpreting surface and borehole geophysical data, and applying the results to provide a

Background and Problem Tully Valley is part of the Onondaga Trough, which extends from the Valley Heads Moraine in the south to Onondaga Lake in the north near Syracuse, New York (fig. 1). The Onondaga Trough is filled with a complex sequence of glacial and post-glacial sediments that overlie Devonian carbonate rock and shale and Silurian shale and salt (fig.2). Mudboils, volcano-like cones o

One of the most important concepts to understand is that volumes of water pumped from a groundwater system must come from somewhere and must cause a change in the groundwater system. Another important concept is that water table aquifers are hydraulically connected to the streams that drain them. Therefore, pumping water from aquifers that are hydraulically connected with surface-water bodies can...
