Volcanic aquifers of Hawai‘i—Hydrogeology, water budgets, and conceptual models
Scot K. Izuka, John A. Engott, Kolja Rotzoll, Maoya Bassiouni, Adam G. Johnson, Lisa D. Miller, Alan Mair
2018, Scientific Investigations Report 2015-5164
Hawai‘i’s aquifers have limited capacity to store fresh groundwater because each island is small and surrounded by saltwater. Saltwater also underlies much of the fresh groundwater. Fresh groundwater resources are, therefore, particularly vulnerable to human activity, short-term climate cycles, and long-term climate change. Availability of fresh groundwater for human use...
