Detailed Description

 Groundwater in Storage on Long Island, New York: The figure above shows a simplified estimate of water stored in the Long Island aquifer system based on the total area of Long Island (~1,400 sq mi), average thickness of the aquifer above the Raritan confining unit (~700 ft), and an assumed specific yield value of 0.25.  Based on these assumptions, there is about 50 trillion gallons (Tgal) of water in storage. (Figure for illustrative purposed only, data subject to change.)
