Attempts were made to increase an efficiency of soil contamination investigation systems (SCISs) including Soil Network 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 on 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 Network 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.

Constructing the national inventory that can be used as a tool to identify and assess existing or potential contamination is necessary for efficiently managing the soil and groundwater contamination. In order to start this construction, the first step is how we define and classify potential contamination sources of soil and groundwater. After selecting the basic classification model of contamination sources from developed countries, we suggested the classification and list of the potential contamination sources of soil and groundwater which are appropriate for specific conditions of South Korea. In addition, we investigated several databases to confirm the existence of available data sources and then examined established attribute data through chemical accident response information system (CARIS) and water information system (WIS) in National Institute of Environmental Research and mine geographic information system (MGIS) in Mine Reclamation Corporation. All sorts of attribute data in the existing databases can be utilized as significant assessment factors for determining the management priority of potential contamination sources in the future. Therefore, it is required the expanded investigation of additional database sources and the continual modification so that the classification system of potential contamination sources can be improved.

Objective: The purpose of this study was to create soil contamination maps using QGIS (Quantum Geographic Information System) and suggest selection methods for soil pollution sources for preferential investigation in a soil contamination survey. Method: Data from soil contamination surveys over five years in Gyeonggi-do Province, South Korea (2013-2017) were used for making soil contamination maps and analyzing the density of survey points. By analyzing points exceeding the concern level of soil contamination, soil pollutant sources for priority management were identified and selection methods for preferred survey points were suggested through a study of the model area. Results: A soil contamination survey was conducted at 1,478 points over five years, with the largest number of surveys conducted in industrial complex and factory areas. Soil contamination maps for copper, zinc, nickel, lead, arsenic, fluoride, and total petroleum hydrocarbons were made, and most of the survey points were found to be below concern level 1 for soil contamination. The density of the survey points is similar to that of densely populated areas and factory areas. The analysis results of points exceeding the criteria showed that soil pollutant sources for priority management were areas where ore and scrap metals were used and stored, traffic-related facilities areas, industrial complex and factory areas, and areas associated with waste and recycling. According to the study of the model area, the preferred survey points were traffic-related facilities with 15 years or more since their construction and factories with a score of 10 or more for soil contamination risk. Conclusion: Soil contamination surveys should use GIS for even regional distribution of survey points and for the effective selection of preferred survey points. This study may be used as guidelines to select points for a soil contamination survey.

Land contamination has emerged as a major environmental and land management issue over the last decade. Although the importance of contaminated land management was continuously increased and many developed countries tried to make advanced contaminated land register system, current Korea soil regulations and policies have not been considered yet. This study analyzed existing or developing contaminated land register system from various countries to suggest implications of environmental decision support. Through this study, the introduction of contaminated land management system as creating a new system in Korea needs to considerable review to the following in order to achieve the objective through a effective adoption and operation (1) we need to establish contaminated land register system by providing a proper legal basis before the imposition of data collection, investigation, and management, (2) sufficient examination is required to identify scope of information disclosure and criteria, contents, and subjects of items from contaminated land register system.

이 연구는 폐금·은광산 주변의 토양과 수계에서 비소(As), 카드뮴(Cd), 구리(Cu), 납(Pb), 안티모니(Sb), 아연(Zn)의 지구화학적 분산 특성을 확인하였다. 토양시료 내 각 원소의 지구화학적 오염도는 enrichment factor (EF), geoaccumulation index (Igeo), pollution load index (PLI)와 같은 지화학 지수를 이용해 평가하였다. 수계의 지구화학적 오염도는 광물찌꺼기 적치장에서부터 거리에 따른 중금속 및 황산염(SO₄^2-)의 농도 변화를 이용하여 평가하였다. 지화학 지수를 이용한 토양의 오염도 평가 결과 광산 및 광물찌꺼기 저장시설과 가까운 지역에서 As, Cd, Pb, Zn의 농축지수가 높게 나타났으며, Sb는 모든 토양시료에서 높은 농축지수를 보였다. 이러한 결과는 광산 활동으로 대표되는 인위적인 요인에 의해 주변의 토양으로 중금속의 분산이 진행되었음을 보여주는 결과이다. 수계에서 중금속 농도 및 SO₄^2-의 농도 변화를 확인한 결과 특정 지점에서 As, Cd, Zn, 그리고 SO₄^2- 농도의 이상점이 나타났으며, 거리에 따라 점차 각 원소의 농도가 감소하였다. 이는 수계의 오염이 광물찌꺼기 적치장과 그 인근의 황화광물의 풍화에 기인한 것을 의미한다. 조사를 수행한 지역에서는 과거에 중금속으로 오염된 토양의 복원사업이 진행되었지만, 그 이후에도 잠재적인 오염원인 광물찌꺼기 적치장 인근에서부터 오염이 다시 진행되고 있는 것으로 판단된다. 따라서 복원을 완료한 지역에서도 토양과 수질시료를 대상으로 지속적인 모니터링이 필요할 것으로 판단된다.

To respond to rapidly changing water circumstances such as climate change, drought, etc., the korean government (MOE) established four advanced strategies for integrated groundwater management. The first strategy is watershed-based management of groundwater. The second strategy is total quantity management of groundwater including improvement of groundwater preservation area policy and procedure of investigation for groundwater influence area, additional construction of groundwater dam, installation of large-scale public wells, extention of spilled groundwater use. The third strategy is prevention of groundwater contamination including expansion of monitoring wells, introducing declaration of groundwater contamination. The last strategy is advancement of groundwater information management including integrated management of data, setting up a big-data based open platform. The above-mentioned four strategies will be reflected in the 4th National Groundwater Management Plan to secure implementation power, and it is expected to laid the foundation for advanced and rational groundwater management system.

Traditional investigation procedures of soil and groundwater contamination are followed by soil gas sampling, soil sampling, groundwater sampling, establishment of monitoring wells, and groundwater monitoring. It often takes several weeks to obtain the analysis reports, and sometimes, it needs supplemental sampling and analysis to delineate the polluted area. Laser induced fluorescence (LIF) system is designed for the detection of free-phase petroleum pollutants, and it is suitable for on-site real-time site investigation when coupling with a direct push testing tool. Petroleum products always contain polycyclic aromatic hydrocarbon (PAH) compounds possessing fluorescence characteristics that make them detectable through LIF detection. In this study, LIF spectroscopy of 5 major fuel products was conducted to establish the databank of LIF fluorescence characteristic spectra, including gasoline, diesel, jet fuel, marine fuel and low-sulfur fuel. Multivariate statistical tools were also applied to distinguish LIF fluorescence characteristic spectra among the mixtures of selected fuel products. This study successfully demonstrated the feasibility of identifying fuel species based on LIF characteristic fluorescence spectra, also LIF seemed to be uncovered its powerful ability of tracing underground petroleum leakages.

This study has researched the management status and the pollution level of water, soil, stream sediments of 11 abandoned coal mines out of a total of 12 within Obong-Dam area except Bukyung mine, which was submerged when constructing Obong-Dam, and selected areas which are in needs to have pollution control facilities in the first place. From the results of examination on the runoff at the waste rock pile and mineheads, the runoff from Sueun mine (pH, Fe, Al), Samwon mine (pH, Al), Wangdo mine (pH, Al), Mose mine (pH, Fe, Al) and Daeryeong mine (pH) exceeded the permissible discharge standards of the water quality, but the water at merging point with Obong-Dam after joined with Doma branch satisfied both Water Quality Standards and Drinking Water Quality Standards. In regard to groundwater contamination, it is found that areas where exceeded the Drinking Water Quality Standards are Wangdo mine (pH), Jangjae mine (pH, Zn), Daeryeong mine (pH) whereas all areas satisfied Soil Contamination Warning Standards of Soil Environmental Conservation Law. When comparing a research result on underwater sediments of branches of abandoned mines to the EPA Guidelines for classification of great lakes harbor sediments, Dongguk Gaerim (Fe), Jungwon mine (Fe), Daebo mine (Mn), Samwon mine (Mn) and Daeryeong mine (Mn) showed mid-level of contamination, whereas Sueun (Fe, Mn), Daebo mine (Fe), Woosung mine (Fe, Mn), Wangdo mine (Fe, Mn), Mose mine (Fe) and Daeryeong mine (Fe) showed high-level of contamination. In addition, contamination levels of underwater sediments in Wangsan and Doma branch where abandoned mine's branches merge together, Wangsan branch showed no contamination at all whereas Doma branch shows mid-level of contamination which reflect the Doma branch is affected by waste rock pile and minehead runoff of the abandoned mines in the Doma branch area. It is concluded that Mose mine and Sueun mine required treatment of acid mine drainage. and Wangdo, Jungwon, and Samwon mines were in need of mine tailing and erosion control work. The Samwon mine additionally required a control system for closed minehead runoff. Although the Samwon mine reached a high concentration of Al, Mn $Ca^{2+}$, $SO{_4}^{2-}$ in the runoff, the levels decreased after it was combined with a tributary. It has been concluded that after further monitoring of the cause of pollution, a preventive measure system may be needed to be built.
