Abstract

In this study, the efficiency of natural attenuation was evaluated through the hydrogeological characteristics such as monitoring and analyses, tracer tests, chemical composition analysis of the groundwater at a military site contaminated by petroleum hydrocarbon in korea. Also, based on the results, the natural attenuation rate by distance and the expressed biodegradation capacity(EBC) was evaluated. The regression slope of -0.0248($K/V_x$) and bulk attenuation rate of $1.7{\times}10^{-3}/day$ were calculated respectively. The range of total expressed biodegradation capacity(EBC) of BTEX was shown from 9.1 mg/L to 10.0 mg/L(average 9.7 mg/L). It was confirmed that the denitrification which was expressed about 63.6% in the total EBC is the largest influence redox process. Consequently, the biodegradation capacity is considered to be sufficient for remediation in the BTEX average concentration of 1.326 mg/L.

본 연구에서는 유류오염 지역인 유류보급 군부대 일대의 지하수에 대한 수질 측정 및 분석, 추적자시험, 지하수유형분석 등 수리지질학적 특성을 통하여 오염부지에서 나타나는 자연저감의 효과를 파악하였다. 또한 이 결과를 반영하여 최종적으로 거리별 자연 저감율 및 발현된 생분해능 등을 평가하였다. 거리에 따른 자연저감율을 평가한 결과, 선형기울기($K/V_x$)는 -0.0248로 계산되었으며 산정된 체적저감율은 $1.7{\times}10^{-3}/day$로 나타났다. 연구지역의 발현된 BTEX 총 생분해능은 9.1~10.0 mg/L의 범위(평균 9.7 mg/L)에 있으며 탈질화 과정이 약 63.6%로 가장 큰 영향을 주는 redox 과정임을 확인하였다. 본 유류오염지역의 지하수 BTEX 오염농도 평균 1.326 mg/L임을 고려할 때 생분해능은 충분할 것으로 판단된다.
