Groundwater-Storage Depletion 2010 Long Island, New York

Groundwater-Storage Depletion and Estimated Depth to the Water Table in 2010 on Long Island, New York: The figure above illustrates where groundwater-storage depletion in the aquifer system of Long Island, NY may have the greatest effect. The depth to the water table (or unsaturated-zone thickness) varies across Long Island and is less than 11 feet in the areas shown in dark red on the map; generally where groundwater discharges to lakes, streams, wetlands, and estuaries. Therefore, storage depletion of the aquifer system may have the greatest effect in these areas where the depth to water is small. (Figure for illustrative purposed only, data subject to change.)
