On the leeward side of southeastern Oahu, Hawaii, near-vertical dikes have intruded the gently dipping and highly permeable lava flows of the Koolau mountain. These dikes bound the study area on the north and west and internally divide it into the Waialae and Wailupe-Hawaii Kai aquifers. Recharge to these aquifers, 6 and 9 million gallons per day respectively, has created Ghyben-Herzberg lenses that freely float on sea water and discharge to the sea through coastal sediments. -from Author
