|Jeju Island, the largest island located south of the Korean Peninsula, is famous for striking natural features created by volcanic activity. Jeju has gained international recognition as a treasure trove of environmental assets through achievement of UNESCO’s coveted triple crown “Biosphere Reserve,” “World Natural Heritage,” and “Global Geopark.” Among the various natural assets in Jeju, groundwater is the most valuable resource due to the distinctive hydrogeological features of the island. Even though Jeju Island receives the highest quantity of rainfall in Korea, there is no ephemeral stream that flows all year long on the island because of the highly permeable volcanic rock and soil. Due to the lack of surface water, Jeju is highly dependent upon groundwater. Owing to the hydrogeology of Jeju Island, which differs from the mainland, groundwater recharge and sustainable yield is of supreme importance. This is why groundwater is recognized as the “Water of Life” on Jeju.
