In this study, we evaluated the effect of inland pollution sources on seawater and shellfish(Ark shell) in the Yeoja bay after 20.5 and 83.3 mm rainfall events. We analyzed the sanitary indicator microorganism such as total coliform, fecal coliform Escherichia coli (E. coli) and Male-specific coliphage (MSC) in the discharge water of waste water treatment plant (WWTP), major inland pollution sources, seawater and shellfish for 4 days after rainfall events. The range of coliform group and fecal coliform was from < 1.8 to 1,600,000 and from <1.8 to 140,000 MPN/100 mL after rainfall of 20.5 mm and from < 1.8 to 330,000 and from < 1.8 to 230,000 MPN/100 mL after rainfall of 83.3 mm in the discharge water of 13 waste water treat plants. Also The range of fecal coliform and radius of impacted area of 4 contaminants (domestic waste water and stream water) was from 49 to 1,100,000 MPN/100 mL and from 4 to 1,870 m after rainfall of 20.5 mm and from 170 to 130,000 MPN/100 mL and from 58 to 1,794 m after rainfall of 83.3 mm. The fecal coliform of seawater at 21 stations ranged from < 1.8 to 540 MPN/100 mL. And the E. coli level of shellfish at 3 stations ranged from < 18 to 78 MPN/100 g.
