  "description": "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.",
