영문 초록

The characteristics of drinking groundwater quality is analyzed by investigating 5.733 observed data during 1995. 1-1997. 7 in Taeion city. As the analysis of observed data. the 30.1% of them are over the drinking water quality standards in Taejon city and the unfit ratios of each region are 36.4% at Dong-Gu. 32.3% Taeduk-Gu. 312% Jung-Gu. 30.0% Seo-Gu and 25.2% at Yusoung-Gu. The mean concentrations of each item are as follow ; NH₃-N is 0.05mg/ℓ. N0₃-N 3.77mg/ℓ. hardness 95.77mg/ ℓ. KMn0₄ consumption 0.78mg/ℓ. CI¯ 17.24mg/ℓ. pH 723. evaporation remains 187.23mg/ℓ. Mn 0.07mg/ℓ. SO₄^2- 16.84mg/ℓ and F is 0.45mg/ℓ. All of them are found to be under the water quality standard. But that of Fe is 0.21mg/ℓ over the water quality at Taeduk-Gu. so that the cause of pollution must be examined closely. Recently the water quality concentration is found to be increasing rapidly. so that the cause of increase also must be examined closely. The rainfall and unfit ratio of E-coli and bacteria are found to have the hydrologic persistance. The correlation coefficient between them is 0.525. According to the result of fit test. the proper distribution type of NH₃-N. N0₃-N. hardness and Zn is found to be normal distribution. That of KMn0₄ consumption. Mn, Fe, Cl and Al is 2-parameter log-normal distribution and that of SO₄^2-, evaporation remains and F is type-I extremal distribution.
