Does Hawaii have a water problem?

Where does Oahu get its water from?
aquifer
The lens-shaped body of fresh water that exists within Oahu’s porous volcanic rock is called an aquifer, or fresh water lens. This water is among the cleanest anywhere, having been purified through years of percolating downward through soil and volcanic rock. It is the source of water for many wells and springs.
How deep is the water off of Hawaii?
Unlike on land where high elevations are relatively rare, much of the world ocean consists of very deep basins. On the Seafloor Map of Hawaiʻi, for example, the maximum depth is -5,795 meters and depths between -4,000 and -5,000 meters predominate.
How did Polynesians get drinking water?
Water was carried in gourds and sections of bamboo and stored along with drinking coconuts wherever space or ballast needs dictated.Slips, cuttings, tubers and young plants were first swathed in fresh water-moistened moss, then swaddled in dry ti-leaf, kapa (bark cloth), or skin from the banana tree.
How did Polynesians get fresh water?
Apart from stores of water in gourds, coconuts and fish or seabirds, they were also able to catch and store rain water as replenishment.
How do islands without rivers get fresh water?
How do islands without rivers get fresh water? – Quora. Because fresh water is not as dense as mineral laden salt water, a bubble or lens of fresh water occurs under and sometimes around the island. The heavier salt water acts like a wall holding the lens of fresh water from dispersing.
Are there shortages in Hawaii?
Shortages at mainland grocery stores are being seen to a lesser extent in Hawaii. Supply chain issues have left many mainland grocery shelves with uneven inventories as COVID-19 upended several agriculture and retail sectors.
