강원 유류오염지역의 수리지질 특성 연구

초록

Estimations of porosity and bulk density, particle size analysis of soli samples, tracer test and slug test were performed in a petroleum contaminated area of Kangwon for understanding characteristics of the aquifer. Porosities of the samples were estimated 0.158~0.257, and bulk densities were estimated as 1.73~2.10 g/cm³. Majority proportion of the soil samples was 0.5~1.0 mm size. In the soil texture triangle, all samples were distributed at sand area. Uniformity coefficients were estimated as 7.71~10.39, and thus all samples were poorly-sorted. In the tracer test, Darcy velocity was estimated to 4.8 × 10⁻⁶ cm/day, effective porosity was 0.175, and longitudinal dispersivity was 0.1 m. According to the slug test,hydraulic conductivities of the test wells were estimated as 2.243 × 10⁻²~ 1.634 × 10⁻²cm/sec. These hydrogeologic parameters can be used for efficient remediation design of the petroleum contaminated area.
