The aquifer beneath a circular oceanic island has a mean hydraulic conductivity of 312 ft/day. The amount of recharge is 0.00831 ft/day. The density of fresh water is 1.000 g/cm³
and the density of underlying saline water is 1.024 g/cm³. If the island is 8715 ft in diameter, what is the depth to the salt-water interface in the center of the island?
