Palawai Basin From Lanaihale

This hydrogeochemical assessment will reveal Lāna‘i’s groundwater system, inform water conservation, and expand our understanding of groundwater systems within the caldera regions of the Hawaiian volcanoes.

Water wells within the Pālāwai Basin tap high-level brackish water at elevated temperatures. As the only location in Hawai‘i where brackish water flows above sea level, this caldera region of Lāna‘i volcano rise hundreds of feet above sea level. Where this high-level brackish water comes from is unknown. We plan to deepen two existing wells within Lāna‘i’s Pālāwai Basin by using core drilling technology (core will be less than 4 inches diameter).

We will provide project updates on our groundwater research on Lāna‘i Island, so welcome and stay tuned!
