  • Attempts were made to increase an efficiency of soil contamination investigation systems(SCISs) including Soil Contamination Fact-Finding Investigation Sites and Special Soil Contamination Management Facility Sites in Korea. In order to increase low efficiencies resulting from inappropriate SCISs, possible policy suggestions are driven based on the results from problem findings of Korean policy and comparisons of policies in industrialized countries including United States, United Kingdom, Germany, the Netherlands and Japan. First, functions of Soil Environment Conservation Act(SECA) on liability should be updated and reinforced to initiate a soil contamination investigation process for stakeholders including an owner(s) or a responsible party(ies) of the potentially soil contamination sites positively. Second, appropriate SCISs should be emerged for implementing the Soil Contamination Fact-Finding Investigation Sites and Special Soil Contamination Management Facility Sites properly. Stakeholders for the potentially contaminated sites should easily access and raise the soil contamination issues, and soil contamination investigation implemented by liable and profit environment (consulting) companies should be encouraged. Third, the soil contamination reporting system of SECA needs to change legally responsible. Further more, public announcement system showing soil quality of a site which exceeds a certain scale would be considerable. Fourth, liable environment (consulting) companies should legally execute Soil Environment Assessment of SECA.

  • 중금속으로 오염된 폐광산 주변부나 유류누출로 인한 토양오염 등과 같은 오염부지에 대한 환경조사는 그 결과를 토대로 환경계획이나 정책이 수립되므로 의사결정의 기초가 된다. 이때, 의사결정의 타당성은 오염부지 조사결과 오염도가 얼마나 정확하게 측정되었느냐에 따라 달리 평가되어 진다. 그러므로 이와 같은 환경조사는 측정결과의 불확실성이 감소되도록 정밀한 시료채취방법이나 분석방법을 고안하여 적용해야 한다. (중략)

  • 토양과 지하수 오염은 오염원이나 그 정화 방법에 있어서 서로 밀접한 관계를 가지고 있으며, 수질오염이나 대기오염과 달리 일단 한번 오염이 되면 오염 정화과정이 매우 복잡하고 어려우면서도 비용이 많이 드는 특성을 갖고 있기 때문에 오염원의 형태에 따른 통합된 관리 및 효율적 정화기술의 적용이 무엇보다 필요하다. 따라서 표준화된 오염조사 절차 (Environmental Site Assessment)를 통해 대상부지를 조사한 후, 확인된 오염원의 정화를 위한 기술을 선정함에 있어 필요한, 오염원·대상부지 특성 및 사업환경에 따른 정화기술에 대해 설명하고, 토양 및 지하수 통합 정화기술의 적용 예를 들어 토양과 지하수를 통합·관리함이 필요함을 살펴보고자 한다.

  • In order to decommission safely nuclear power plant, it is necessary for the procedure of residual radioactivity investigation in site to provide detailed guidance for planning, implementing, and evaluating environmental and facility radiological surveys conducted to demonstrate compliance with a dose or risk-based regulation. This study presents the procedure of residual radioactivity investigation in decommissioning site - Historical Site Assessment, Scoping Survey, characterization Survey, Remedial Action Support Survey, Final Status Survey - on the basis of MARSSIM(Multi-Agency Radiation Survey and Site Investigation Manual) and investigation cases of decommissioned or decommissioning nuclear power plant.

  • 오염부지 관리 기조가 매체 중심에서 수용체 중심으로 변화하면서 우리나라에 위해성평가 제도가 도입되었으나, 이를 오염현장에 충분히 활용하기 위한 체계와 관련 기술들은 아직 제대로 확립되어 있지 않다. 특히, 여러 가지 이유로 정화곤란부지로 분류가 되는 오염부지의 정화 및 관리와 그러한 부지에 적용될 수 있는 위해저감기술들에 대한 기술적, 사회적 논의와 합의도 부족한 실정이다. 본 연구에서는 그동안 오염토양의 정화에만 초점이 맞추어진 우리나라의 토양환경정책이 오염부지의 관점에서 그와 연결된 수용체를 보호하는 방향으로 나아가기 위해 필요한 위해성기반 오염 부지관리 의사결정체계를 제안하고, 그러한 관리체계가 현장에서 적절히 적용되도록 하기 위해 필요한 위해저감기술들을 조사, 분류하여 위해저감 방식에 따른 위해저감기술의 활용성 및 적용성을 평가하는 방안을 제안하였다.

  • Purpose : The subject site selected in this study was a place that was prepared through the reclamation of foreshore completed in 1973. Since then, the site has been occupied by the industry of ship repair for over 30 years. Method : The results of a precise soil examination conducted in 2013 showed that the site was seriously contaminated with TPH over an area of $10,000m^2$ and GL(-)3.0m in depth, with an expanding coverage of contamination. Results : The soil contamination by refined petroleum products often results in adverse effects to human health and ecological systems, thus the contamination should be purified as soon as possible. Conclusion : Hydrogeological investigation can be employed to assess the groundwater movement and propagation of contamination to determine the potential agents or contaminants in the soil contaminated with high concentration TPH.

  • The risk of the soil and groundwater that contaminated with petroleum is well known. The behaviour of petroleum in subsurface is governed by combined mechanism of several processes such as volatilization, adsorption, dissolution, biodegradation, etc. Large number of methods of remedial investigation and plan, therefore, have been developed and practiced. In application of the method, it is required engineer understands the mechanism of fate of petroleum in subsurface. So sampling procedures is very important for investigating the type of contaminants and their concentration as well as the selection of items that must be tested. For designing the remedial method, it is also required engineers to verify the structural formation of geology and the locational conditions of a land in detail, to familiar with the regulation, and to investigate the problems that can be happened after the performance was begun. In this paper it is shown that the investigation methods of contaminated land and the proper selection procedure of remedial method using the case history.

  • Investigations on the contaminated lands due to heavy metals from mining activities or hydrocarbons from oil spillage for example, should be planned based on specific fitness-for-purpose criteria(FFP criteria). A FFP criterion is site specific or varies with situation, based on which not only the data quality but also the decision quality can be determined. The limiting factors on the qualities can be, for example, the total budget for the investigation, regulatory guidance or expert's subjective fitness-for-purpose criterion. This paper deals with planning of investigation methods that can satisfy each suggested FFP criterion based on economic factors and the data quality. To this aim, a probabilistic loss function was applied to derive the cost effective investigation method that balances the measurement uncertainty, which estimates the degree of the data quality, with the decision quality. In addition, investigation planning methods when the objectives of investigations do not lie in the classification of the land but simply in producing the estimation of the mean concentration of the contaminant at the site(e.g. for the use in risk assessment), were also suggested. Furthermore, the efficient allocation of resources between sampling and analysis was also devised. These methods were applied to the two contaminated sites in the UK to test the validity of each method.

  • Recently, the branch-out of foreign companies into domestic markets through M&A and the opened followed by the Free Trade Agreement(FTA) with America have made the environmental site assessments of specific site more necessary. In this study, through case study of conducting actual environmental site assessment by use of a toolbox approach at a large scale of chemical plant with various contaminants located in a coastal area, the problems of guideline of domestic environmental assessment of soil were complemented. And an efficient and economical assessment was achieved. All six steps such as basic investigation, environmental site history survey, sampling and analysis, installation of monitoring wells and hydrogeological survey, and data interpretation were conducted in this study. All results of document survey, geological lineament analysis, field geology survey of surrounding area, geophysical prospecting of the site, hydraulic conductivity, measurement of groundwater flow rate and direction, sampling and analysis at each step were associated and estimated as an integrated tool box approach. As a consequence of this study, toolbox approaches were very useful techniques for contamination level and site characterization of subsurface media. The given conditions to conduct a basic survey for domestic soil environment assessment of site by use of existing documents, as well as interviews with the owner/manager/user of all adjacent properties and thorough review of all practically reviewable records pertaining to the property and surrounding properties within "Guideline for Soil Environment Assessment" radii are very poor. As a result, the application of toolbox approach in the environment site assessment of site is not only more efficient and economical, but also could be very useful assessment to integrate the soil and groundwater contamination.
