Water Table Contours in the Upper Glacial and Magothy Aquifers, April-May 2016
This polyline shapefile consists of digital contours that represent the water table altitude in the upper glacial and Magothy aquifer beneath Long Island, New York. The U.S. Geological Survey constructed a water table altitude map using ground-water levels measured in the upper glacial and Magothy aquifers during the spring of 2016. Contours were constructed at a scale of 1:125,000 from water-level data collected at 276 groundwater monitoring wells. The water table altitude contours were digitized and compared to 1997, 2006, 2010 and 2013 water table altitude maps . The variable contour interval ranges from 5 to 120 feet above the National Geodetic Vertical Datum of 1929 (NGVD29). This polyline shapefile is a digital representation of the potentiometric-surface contours presented in sheet 1 of Scientific Investigations Map 3398.
