Characterization of the groundwater system of Jeju volcanic island, Korea, using environmental tracers: a review

A comprehensive review reveals that environmental tracers are pivotal in unraveling the groundwater dynamics of Jeju Island. These tracers have successfully categorized groundwater processes into six key areas: recharge, flow dynamics, age dating, nitrate sources, salinization, and submarine discharge. The study highlights the effectiveness of these methods while acknowledging their limitations, suggesting innovative approaches to overcome challenges and guide future research. This synthesis provides a robust framework for understanding and managing Jeju Island's critical freshwater resource.
