Swimming Suitability and Management of Sea Water for Artificial created Swimming in the Southwestern Sea of Korea

This study aimed to determine the swimming suitability of sea and to suggest methods to address the problems on sea water color and green plants growing on sediment in the artificial created swimming in the beach of southwestern Korea. Sea water samples were collected from January to December of 2010 and analysis for SS, COD, , TP, MPN, sediment IL, ORP and plants on sediment. The results showed that the sea water under the swimming suitability "level of management" based on the relating high levels of SS and TP, but still suitable for swimming on the basis of MPN. Improving exchange seawater flow, dredging, coating and chemical treatment of polluted sediments in addition to removal of point sources and restriction of non point sources in the study area could improve the sea water quality and swimming suitability of the sea.
