본 연구는 묘역의 운영에 의한 지하수의 오염가능성을 조사하기 위하여 경기도 지역의 43개 묘역 중 28개를 대상으로 수행하였다. 이를 위하여 대상 묘역에 일곱가지의 수리지질학적 인자들(지하수위, 지하수 함양량, 대수층 매질, 토양 매질, 지형 구배, 비포 화대 구성물질, 대수층의 수리전도도)을 사용하여 지하수 오염 가능성을 평가하는 DRASTIC 모델을 적용하였다. 본 연구에서 연구대상지 DRASTIC 지표는 82 126범위였고 평균은 113.99(1.48)이었다. 연구대상지인 경기지역의 묘역의 DRASTIC 지표는 북부가 남부보 다 상대적으로 높은 값을 보였다. DRASTIC 지표는 동일한 매장률과 매장밀도를 가지는 지역들 간에는 비슷한 값을 보였다. 이 연구는 DRASTIC 모델을 이용하여 묘역의 지하수 오염가능성을 평가할 때 모델적용에 필요한 일곱 가지 기본 인자뿐 아니라 매장률과 매장밀도도 고려하는 것이 필요함을 보였다.
The purpose of this study was to investigate the vulnerability for groundwater contamination at the some cemeteries in Gyeonggi Province. Twenty-eight out of 43 cemeteries in Gyeonggi province were selected for this study. The DRASTIC model was applied to those cemeteries, and the reliance of the model was assessed using the water quality data of the target areas. The DRASTIC model was used for the assessment of the potential for groundwater contamination using hydrogeological factors. Seven factors including depth of water, net recharge, aquifer media, soil media, topography, impact of the vadose zone, hydraulic conductivity of the aquifer were assessed. The DRASTIC index of the study area ranged from 82 to 126 with an average value of $113.99(\pm11.48)$. The DRASTIC index was relatively greater in the northern Gyeonggi province than that in the southern area. The DRASTIC index was similar for the areas with the similar burial rate and burial density. This study demonstrated that burial rate and burial density should be considered along with the 7 basic factors for the evaluation of groundwater vulnerability of the cemeteries.
