每水洛場의 大陽菌汚染에 對한 調査硏究

A Study on the Coliform Contamination of Sea Water at Bathing Places in Korea

A study was carried out to find out the bioJogical contamination of beaches in Korea from May- 16, to June 2, 1972. Turbidity was measured and co1iform groups were examined by membrane filter method as well as generaJ sanitary condition of beaches. Main findings were as follows: 1. The average coliform group count was 5.0 per 100 ml of tested wateζ and the range 이 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 watcr samples from rising tides was 2.8/100 m!. The range of coliform count from rising tide was 0-26/100 ml, and those from receding were 1-120/100m!. 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. Qppm). 4. Out of 8 beaches surveyed shower facilities existed at only 4 beaches (50%), howcver the drainages of showers and bath rooms were not sanitarily adequate.
