매립장 인근 지하수질이 LPG 저장 공동의 수리지질학적 특성에 미치는 영향 Influence of Underground Water Quality Adjacent to Landfill Site on Hydrogeologic Characteristics of LPG Storage Cavern원문보기
석유 제품 지하 저장 공동의 지하수 수질은 공동 인근 매립지 수질의 영향을 받는다. 매립지 주변의 지하수 수질 분석 결과, 시료의 반 정도에서 지하공동 수질에 영향이 미미한 농도의 As, Cu 및 Pb가 검출되었으며, Cd, Hg, $Cr^{6+}$, $CN^-$, TCE, PCE 및 Pheno은 검출되지 않았다. $COD^{Mn}$의 농도는 모든 시료에서 $8.0mg/{\ell}$이하로 유기물질에 의한 지하수 오염은 거의 없는 것으로 분석되었다. 1차, 2차 미생물 분석결과 총박테리아는 각각 $94.84{\times}10^4cells/{\mu}g/m{\ell}$과 $146.26{\times}10^{-4}cells/{\mu}g/m{\ell}$이고 황산환원 박테리아는 $2cells/m{\ell}$이하로 분석되어 지하공동의 수질에 영향이 미미할 것으로 분석되었다. 저장 공동 인근 지역의 지하수 수질 분석은 공동의 수리 지질의 안정성을 향상시키기 위하여 지속적인 조사와 관리가 필요할 것으로 판단된다.

The underground water quality of petroleum products storage cavern is influenced by that of dumping and landfill sites adjacent to cavern. From the chemical analysis of underground water sampled from landfill site, insignificant amounts of As, Cu and Pb were detected in a half of test samples while Cd, Hg, $Cr^{6+}$, $CN^-$, TCE, PCE and Phenol were not detected in all samples. All measurements of $COD^{Mn}$ were below $8.0mg/{\ell}$ that can be negligible for the contamination by organic matters. The total bacteria counted from 1st and 2nd microbiological analysis were $94.84{\times}10^4cells/m{\ell}$ and $146.26{\times}10^{-4}cells/m{\ell}$, respectively, and all counts of the sulfate reducing bacteria were less than $2cells/m{\ell}$. It can be suggested that the water quality adjacent to storage cavern can also be studied to improve the reliability of hydrogeologic stability of storage cavern.

And the chemical and microbiological changes in porous spaces around the cavern can vary the amount of solid content in channels that may cause clogging, and can also damage underground facilities due to corrosion(Lim, 2001). Dissolved oxygen(DO), pH, electrical conductivity(EC), and oxidation-reduction potential(Eh) of groundwater those affecting the chemical environment of subsurface were measured at the sampling sites, and the other chemical and biological factors were analyzed in the laboratory. Total dissolved solid(TDS) was analyzed to determine concentration and extent of contamination.
The underground water quality of dumping and/or landfill sites adjacent to the cavern can affect the hydrogeologic characteristics of petroleum products storage cavern. In this study, the hydrogeologic interrelationship between landfill and cavern areas can be inferred by analyzing groundwater quality of landfill. And the chemical and microbiological changes in porous spaces around the cavern can vary the amount of solid content in channels that may cause clogging, and can also damage underground facilities due to corrosion(Lim, 2001).
The chemical and microbiological analysis of groundwater in the vicinity of cavern was carried out to study the influence of chemical elements and microorganism on hydrogeologic environment of the cavern. From the hazardous heavy metal analysis, As concentrations were determined 9 out of 30 samples, and Cu and Pb were detected from 6 samples.

, 1992), ions were analyzed ICP-OES(Vista-MPX, Varian) and IC(761, Metrohm), respectively. Total organic carbon(TOC) was determined using UV-Persulfate TOC Analyzer(Dohrmann, Phoenix 8000) according to Standard Methods 5310c(AWWA, 18th Ed., 1992). Alkalinity was determined under the regulation of Standard Methods 2320(AWWA, 18th Ed.
