A Study on the Analysis of Well-water in a Suburban Area in Taegu City
대구시(大邱市) 일부지역(一部地域) 우물물의 위생학적(衛生學的) 고찰(考察)
Abstract
Wells are perticularly able to be a source of water-borne infections disease in the army society. Owing to untreated drinking water, high indidence of water-borne diseases are encounted in Korea. This study was carried out to evaluate the physicochemical and bacteriological states of 298 wells in army camps around Daegu city during a year from January to November, 1974. Main findings are summerized as follows: 1. Turbidity, Colorness & odor was within normal range in all samples. 2. Reaction of pH, cnsumption of KMnO4, total hardness and chlorine ion as over almost within normal range. 3. Free Ammonia was detected to 33.2% positive, and nitrite, 45.5% positive. 4. In the bacteriological test 40.3% of all samples were over the standard limit on E. Coli. 5. In comparison of nitrate and E. Coli detection, 60.1% of nitrite was over the standard limit out of the positive cases detected E. Coli. and all of E. Coli were over the standard limit out of the positive cases of nitrite. 6. The contamination was very remarkable in the spring and summer, and very diminished in the autumn and winter.
