The analysis of chemical and biological factors of underground water surrounding LPG(Liquefied petroleum gas) storage cavern has significance in understanding of the hydrogeologic characteristics of rockmass. The in situ and laboratory analysis of underground water was carried out to investigate the influence of geochemical elements and activity of microorganism on the cavern. The results of chemical analysis both in situ and laboratory did not show noticeable influence on hydrogeologic environment. From the biological analysis, the factors has little influence on the permeability of subsurface in the vicinity of the cavern. Sea water intrusion to the base and some variations in measurements were noticed, but it is inferred to be little influence on hydrogeologic characteristics of the storage cavern. It can be remarked that the storage cavern investigated does not significantly influenced by the chemical and biological characteristics of underground water. And continuous study and monitoring will be required to maintain appropriate hydrogeologic environment and to secure storage base.
액화석유가스의 지하 저장 공동 주위의 지하수에 대한 화학적, 미생물학적 분석은 암반의 수리지질 특성을 이해하는데 중요하다. 지하수질이 저장기지 주위 암반 특성에 미치는 영향을 조사하기 위하여 화학적, 미생물학적 요소의 분석하였다. 현장과 실험실에서의 화학적, 미생물학적 분석 결과, 조사 지역의 지하수 수질이 공동 주위 암반의 지질 환경에 영향을 미치지 않는 것으로 조사되었다. 대수층을 통하여 기지 주위로 인접 바다의 해수 유입과 다소의 측정치의 변화가 있는 것으로 나타났으나, 저장 공동의 수리 지질 특성에 특별한 영향을 주지 않는 것으로 추정된다. 조사된 저장 공동은 지하수의 화학적, 미생물학적 특성에 크게 영향을 받지 않는 것으로 나타났으며, 앞으로 저장 기지의 적정한 수리 지질 환경을 유지하고 안정성을 확보하기 위하여 지속적인 조사와 관리가 필요할 것이다.
