초록

본 연구의 목적은 금산 생활쓰레기 매립장을 대상으로 지하수의 수리지 화학적 특성과 통계분석을 통하여 침출수의 누출원인과 누출경로 및 영향범위를 파악하고, 매립지로부터 발생되는 오염물질인 침출수의 누출이 연구지역의 지하수환경에 미치는 위해요인에 대해 정량적으로 평가하는 것이다. 본 연구를 위해서 수질 검층, 침출수와 지하수 수질 분석 및 통계분석, 그리고 오염물질 이동모델링 기법 등을 이용하였다. 수질검층 결과 침출수 집수정 부근에서 침출수가 주변 대수층으로 누출되고 있었으며, 매립장과 인접한 하류부 관측정의 4-12m 깊이에서 지하수에 대한 침출수의 영향을 확인할 수 있었다. 침출수는 유출 범위는 매립장으로부터 70-100m 내외이며 오염된 지하수에서 전기전도도는 $400-750{\mu}S/cm$를 나타내었다. 주성분분석수행 결과 주성분 1과 2는 각각 침출수과 대수층의 매질 특성을 나타내었다. 주성분분석결과는 또한 침출수의 영향을 받는 지하수의 수질 변화에 의해 나타내어지는 양이온교환반응, 흡착 및 미생물 생분해 같은 자연저감과정을 나타내었다. 지하수 흐름 및 오염물 이동 모델링 결과 지하수는 매립장에서 서쪽으로 계곡을 따라 흐르며, 오염물질은 그에 따라 이동함을 알 수 있었다.

The purposes of this study are to investigate the hydrogeochemical characteristics of groundwaters around Keumsan municipal landfill, and to evaluate the contaminant dispersion from the landfill and its environmental impact. To achieve these goals, groundwater quality logging, hydrochemical analysis, multivariate statistical analysis, and contaminant transport modeling were performed. The water quality logging indicated a leaking from the landfill at the depth of 4-12m around a leachate sump. Electrical conductivity data indicated that groundwaters within 70-100m from landfill were affected by the landfill leakage. Principal components 1 and 2 obtained from principal components analysis (PCA) reflect the influence of leachate and the characteristics of aquifer media, respectively. The results of principal component analysis also indicated the natural attenuation processes such as cation exchange, sorption, and microbial biodegradation. The modeling results showed that groundwater flow westward along a valley from the landfill and contaminants transport accordingly.
