Abstract

We hydrogeologically studied a mountainous area and its vulnerability to groundwater contamination. Groundwater flow and recharge occur mainly through a network of fractures in this areaTransmissivity and storativity obtained from slug, slug interference, and pumping tests range from 3.2$\times$10$^{-3}$ to 2.0$\times$10$^{-2}$$m^2$/min and 1.3$\times$10$^{-7}$ to 9.15$\times$10$^{-4}$, respectively. The groundwater was contaminated bylivestock activities in the upgradient. The groundwater in the downgradient residential area wasthreatened by the upgradient livestock activities.

강원도 흥호리 지역의 수리지질과 지하수의 오염취약성을 평가하였다. 연구지역의 주 대수층은 피압 단열암반 대수층으로 지하수 유동과 재충진이 주로 단열을 통해 이루어진다. 순간수위변화시험, 순간 간섭시험 그리고 양수시험을 통해 얻은 대상 대수층의 평균 투수량계수와 저유계수는 각각 3.2$\times$$10^{-3}$~2.0$\times$$10^{-2}$$m^2$/min, 1.3$\times$$10^{-7}$~9.15$\times$$10^{-4}$이다. 거주지역 상부에 위치한 축산단지의 오수로 인해 단열대의 지하수가 오염되었고 오염지하수가 단열대를 통해 이동함에 따라 하부 주민거주지역의 음용 지하수의 오염취약성을 드러내고 있다.
