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...

Background Borehole drilling and well-installation are costly procedures, and securing funding for new well installation for the sake of research is often difficult.The Suffolk County Water Authority (SCWA) maintains a large network of deep wells for public supply that is constantly being upgraded as water demands increase. During the drilling process, contractors record drillers’ logs and collect cores and, subsequently, often perform borehole geophysical logging for determination of aquifer properties. However, although these data may suffice for selecting a screen zone, they are lacking in more detailed hydrologic information necessary for a better understanding of Suffolk County’s hydrologic...

PROBLEM As part of an effort to sustain a viable water-supply system for 8 million residents in New York City, and 1 million other residents in upstate New York that rely on City water, the New York City Department of Environmental Protection (NYCDEP) has requested a multi-disciplinary study by the U.S. Geological Survey (USGS) to determine the source(s) of water to surface-water sites (springs and expressions) in areas adjacent to the Catskill Aqueduct. In the area near the Delaware Aqueduct, which has been determined by the USGS to have a water-tunnel contribution to flooding issues during periods of high precipitation, the NYCDEP plans to repair the leaks with a grouting procedure. However, without monitoring...

This geospatial data set contains groundwater level contours, well locations, and associated metadata that characterize the potentiometric surface near the Rondout pressure-tunnel in High Falls, New York during November 5–7, 2019, and January 21–22, 2020. The pressure tunnel was shut down and partially dewatered for 74 days from November 11, 2019, to January 23, 2020, for inspection and repairs.

Problem The New York City Department of Environmental Protection (NYCDEP) has asked the U.S. Geological Survey (USGS) to assist in two major studies: 1) delineation of the source(s) of shallow groundwater and the extent that the Delaware Aqueduct is contributing to local flooding issues, and 2) delineation of the structural, geologic, and hydrologic conditions along proposed tunnel construction paths using advanced surface and borehole geophysical methods. The NYCDEP needs to determine the source of groundwater and surface water and their possible relation to leakage from the Delaware Aqueduct in upstate New York. The Delaware Aqueduct, which supplies a significant portion of New York City's water supply, has...
