Delineation of Rock Fractures, Faults, and Groundwater Flow in the Vicinity of Proposed Water Tunnels, New York City and Southeastern New York
Problem - The New York City Department of Environmental Protection (NYCDEP) is constructing or proposing water tunnels under New York City and areas of southeastern New York (Hudson River Basin). These tunnels can intersect faults and fractures that produce large amounts of ground water. For example, one tunnel excavation intersected fractures that produced over 200 gallons per minute of ground-water flow into the tunnel. Consequently, there is a need to determine the potential of intersecting ground-water producing fractures during tunnel excavation. The use of advanced borehole geophysical techniques by the USGS during tunnel excavations in northern Queens County demonstrated that geophysical techniques can...
