The lens-shaped body of fresh water that exists within Oahu’s porous volcanic rock is called an aquifer, or fresh water lens.

Why is the water in Hawaii so salty?

Yes. On the mainland, salt in the soil has built up over time, mostly from sediment and from land that was once under seas or oceans. New volcanic rock is made from molten magma and contains little salt. Not only that, but what very little there is is locked in solid stone.

How does the water cycle work in the Hawaiian Islands?

In the Hawaiian Islands, where we are surrounded by water and have plentiful sunshine, most of the evaporation in our water cycle takes place offshore. Ocean water is warmed by the sun, then water molecules evaporate in the form of vapor, rising into the atmosphere. Aloft, the moisture is blown onshore by trade winds.
