|
Clean water supply is still remained as one of the most important problem for the prevention of water borne diseases in Korea as in other developing countries. Actually in Seoul, densely populated capital of Korea, about- ten percent (10 %) of inhabitants are using untreated well water as the drinking water source. A sanitary survey was carried out on 16 pump wells, 15 wells without lid, and 10 springs in Jungneung-dong area where a foot of Mt. Puk-Ak is located in. In this study, a special emphasis was given to the water temperature, acidity. consumption of KMnO4, hardness, Ammonia-nitrogen, coliform group bacilli, and chlorine demand of the sample waters to investigate potability.
The results obtained were as follow;
1) Average values of the water tested were 6.6(pH), 3.36ppm (KMnO4 consumed), 192. 7 (hardness of well waters), and 10. 1ppm (hardness of spring water) respectively.
2) The quantitative analyze for Ammonia-nitrogen revealed 75.6%, coliform group 73.17%, and chlorine demand 05. 1.Oppm in 50% of samples.
3) There was a significant relationship between the Ammonia-nitrogen positive rate and the coliform group positive rate, that is 68. 2% of total samples showed positive in both the coliform group bacilli detection and the Ammonia-Nitrogen detection.
