Background In recent years, more and more people have become concerned about Long Island's supply of freshwater. Currently, there is no comprehensive, island-wide resource that summarizes recent U.S. Geological Survey (USGS) research related to the Island's aquifer system. A webpage will be developed by the USGS that will compile published data from the hydrologic-surveillance program, in place since the mid-1970’s, and various USGS sources, and supplement this information with more recent seasonal and annual hydrologic technical assistance will be provided to the Suffolk County Water Authority (SCWA) to help them produce an easy to understand annual report that will provide a snapshot of the state of Long Island's...

Water-management alternatives being considered for New York City involve aquifer storage and recovery, or ASR. An ASR system may store surplus water in an aquifer, then later recover this water in times of short supply. The success of an ASR system depends on the quantity and quality of water that can be withdrawn during recovery phases, which are influenced by hydrogeologic, microbiological, and geochemical factors. Mixing surface waters with ambient ground waters within a deep confined aquifer may cause freshwater/saltwater interface movement, clay swelling, mineral dissolution, new patterns of bacterial growth, and other hydrogeologic consequences. In 2005, data were collected at Tottenville, Staten Island,...

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...
