A study was carried out to find out the biological contamination of beaches in Korea from May 16, to June 2, 1972. Turbidity was measured and coliform groups were examined by membrane filter method as well as general sanitary condition of beaches. Main findings were as follows: 1. The average coliform group count was 5.0 per 100 ml of tested water, and the range of coliform. group count was 0~120 out of 8 beaches, Chungmun beach was found to be the least contaminated while Daechun was the most contaminated (23. 3/100 ml), however, those beaches surveyed. were satisfactory as far as bacteriological contaminations were concerned. 2. The average coliform group count of water samples from rising tides was 2.8/100 ml. The range of coliform count from rising tide was 0~26/100 ml, and those from receding were 1~120/100 ml. 3. The average turbidity of the water in Korean western beaches was 5.0 ppm, while that of Chejudo was 2.0 ppm. of 8 beaches surveyed, the turbidity of Daechon beach was the highest (7.0 ppm). 4. Out of 8 beaches surveyed shower facilities existed at only 4 beaches (50%), however the drainages of showers and bath rooms were not sanitarily adequate.
