The pollution of Han river at Seoul areas was investigated by coliform Number from 1969 to 1984. The results were as follows In 1984 coliform number in Guei was 3. 3 x 10³/100ml, and in Dookdo was 4. 3X 10³/100ml, in Bokwangdong was 3. 1 x 10⁴/100ml, in Noryangzin was 7. 0 X 10⁴/100ml, in youngdeungpo was 5. 2 x 10^5/100ml. The more river flows down the more contaminated. Annual distribution of coliform was irregalar but relation to annual precipitations was so most highly significant that the correlation coefficient was -0.83(p<0.01) and coliform numbers as pollution index was more valuable than BOD, COD and evaporated residue. The tendency of coliform contamination through 16 years was slightly down wards from 5.406 in 1969 to 4. 987 in 1984.

In order to investigate the bacteriological quality of in raw milk, we examined standard plate count, coliform bacteria, fecal Escherichia coli, mesophilic aerobic spores, psychrophilic bacteria, Pseudomonas aeruginosa and enterococci in raw milks collected from 58 farms in Choongcheongdo and Kangwondo Province according to spring and summer. In standard plate count, the I class(less than 100,000/ml) milks are 48(82.8%) in spring and 31(53.5%) in summer, II class(100,000~250,000/ml) milks are 2(3.5%) in spring and 4(6.9%), III class(250,000~500,000/ml) are 2(3.5%) in summer and 7(12.1%), IV class(500,000~1,000,000/ml) are 3(5.2%), 6(10.3%) and V class(over than 1,000,000/ml) are 6(10.3%) and 11(19.0%), respectively.
