Abstract

Abstract An Integrated Management Plan for Groundwater Resources in the Coastal areas of Korea (I) As the growth of industry and population has been concentrated in coastal areas that have good access to ports, groundwater development has been accelerated in order to meet the increased demand for water demand. Because of this, the groundwater level has declined and the intrusion of saltwater has expanded which poses a threat to the public water supply and deteriorates the quality of groundwater. Consequently, public concern has risen regarding saltwater intrusion and proper management has been requested. In the southwestern coastal area of Korea, public complaints have accelerated as their water supply system has been contaminated and closed by saltwater intrusion. In addition, a variety of development projects such as Enterprise Cities, Saemangeum Tideland Reclamation, and National Industrial Estates, further threaten the areas groundwater. This study aimed (1) to comprehend the current situation of groundwater development and its management in the southwestern coastal area of Korea, (2) to investigate the state-of-the-art techniques and the case studies from the U.S. and Europe and (3) to suggest policy recommendations. For the groundwater management of coastal areas, there are diverse efforts by governmental agencies and research institutes being carried out. A ’Saltwater Intrusion Monitoring Network System’ has been established by the Ministry of Agriculture and Forestry, and local governments have performed basic surveys of groundwater and prepared management plans based on guidelines from the Ministry of Construction and Transportation. While remarkable outcomes have been achieved by the various research groups, their efforts have resulted in incompatible policies and repeated investments. On the other hand, the management systems of the U.S and Europe were developed by integrating the available techniques for prevention and remediation, the current status of saltwater intrusion, and socio-economic situations. As each investigation and policy implementation was supervised by an integrated management system, their outcomes contributed to ensuring the supply and quality of groundwater. A similar integrated management system is required in Korea in order to provide consistent policies, increase the efficiency of collected data and information, and encourage relevant researches.
