Abstract

From 1998 to 2008, the bacteriological quality of seawater in Kamak Bay, Korea, was monitored. The total and fecal coliforms in seawater were monitored as bacterial indicators, and the level of fecal coliform contamination was used to evaluate seawater quality. In the southern shellfish growing area of Kamak Bay, the observed fecal coliform geometric mean (GM) and estimated 90th percentile did not exceed the quality standards for fecal coliforms in seawater in Korea and th USA (GM<14 MPN/100 mL, 90th percentile<43 MPN/100 mL). The GM and estimated 90th percentile of the fecal coliform levels in the adjacent northern area of Kamak Bay were higher than in the southern area. Stations near wastewater discharge sites and urban areas in the north had the lowest quality and did not meet the bacteriological seawater quality criteria. The high fecal coliform levels in the Seonso coastal region near wastewater discharges and northern urban areas declined significantly following dredging and operation of a sewage treatment plant.
