The environmental factors and the distribution of coliform group were investigated in Suyeong bay on the summer, 1989. The ranges of environmental factors were as follows : Dissolved oxygen $0.54{\sim}6.82m{\ell}/{\ell}$, COD(Chemical Oxygen Demand) 0.28~9.84ppm, Salinity 14.7~33.5%, Nitr...

The environmental factors and the distribution of coliform group were investigated in Suyeong bay on the summer, 1989. The ranges of environmental factors were as follows : Dissolved oxygen $0.54{\sim}6.82m{\ell}/{\ell}$, COD(Chemical Oxygen Demand) 0.28~9.84ppm, Salinity 14.7~33.5%, Nitrite $0.13{\sim}20.49{\mu}g-at/{\ell}$, Nitrate $0.89{\sim}62.77{\mu}g-at/{\ell}$, Ammonia $3.81{\sim}246.98{\mu}g-at/{\ell}$, Silicate $6.12{\sim}177.5{\mu}g-at/{\ell}$. The coliform group ranged $10^4{\sim}10^5/100m\ell$ in the mouth and it was decreased in the open sea. Among the composition of coliform group, E. coli I type was dominent at distance area. The correlation between coliform group and ammonia was r=0.629. There were negative correlation between salinity, dissolved oxygen and coliform group during study period.
