  • Recently problems of soil and groundwater contamination occur in major construction sites of highway, dam and railways. Contaminants of oil fuels are also detected in the former fuel storage facilities of railroad station and army troops of transportation, etc. These facilities are planned as the sites of commercial infrastructures after restoration from pollutants by the law of soil environment conservation of Korea. In this manuscript, the contents of soil environment conservation law including soil assessment and restoration technology are introduced. Recent changes of soil environment area are also analyzed.

  • The statistics of monitoring on soil quality is a report statistics which is made on the basis of Article 15, Environment Strategy Basic Law and Article 5, Soil Environment Conservation Law. This study was conducted according to quality assessment of Korea National Statistical Office. The assessment of quality infrastructure advised that the authority bring up and increase completely responsible officer and secure the budget. The assessment of user satisfaction and reflection of request propose that the statistics is focused on soil background concentration, decrease soil sampling points and extend survey period. The assessment of error management system per processes of detailed preparation suggest change of the statistics objective, a reduction of sampling points and improvement of survey period and soil measurement properties. Accuracy assessment of data proposed cuts of sampling points, accessibility increment and build up of management system linking subordinates and Ministry of Environment. The substantiality assessment of data service demonstrated information environment improvement for users including reference expression and records of statistics table and figure contents.

  • Korea and other countries have made various efforts to preserve soil. During the past several decades, Korea has implemented various policies on soil conservation practices; however, those policies have often lacked consideration of human and ecosystem risk management. while other countries have practiced various policies closely related to risk-based management for contaminated sites. Therefore, there is a great need for a paradigm shift of policy to better manage contaminated sites in risk-based strategies, while applying different management plans for soil and groundwater. In addition, the new policies should be administered with provision to improve soil health and related functions in ecosystem. This study has reviewed the trend in relevant policies in Korea and foreign countries to suggest the future policy directions for contaminated site management in Korea. For better management of contaminated sites, coherent policy that could complement the law, system, and relevant technology is required.

  • Objectives of this research were to fractionate heavy metals in soil samples in the upper Okdong River basin and to assess the potential pollution index of each metal fraction. Soil samples were collected from cultivated land soils and analyzed for physical and chemical properties. pH of cultivated soils ranged from 5.2 to 7.6. Contents of total kelhaldal nitrogen and loss on ignition were in the ranges of 0.6∼2.5%, and 1.9∼12.9%, respectively. Heavy metals in the cultivated land soils were higher in the abandoned closed coal mine near field soils than those in the paddy soils. Total concentrations of metals in the cultivated land soils were in the orders of Zn > Pb > Ni > Cu > Cd, exceed the corrective action level of the Soil Environment Conservation Law and higher than the naturals were abundance levels reported from uncontaminated cultivated land soils. Mobile fractions of metals were relatively small compared to the total concentrations. Soil Pollution Assesment Index(SPAI) values of each fraction of metals were leveled from Non polluted to Moderately polluted based on total concentrations. SPAI values of mobil fractions were lower than those of immobile fractions. Results on metal fractions and SPAI values of the cultivated land soils indicate that field soils samples were contaminated with heavy metals and had potential to cause a detrimental effects on plants. A prompt countermeasure to prevent field soils in the abandoned closed coal mine near fields are urgently needed.

  • 본 연구는 중금속 오염지반의 정화를 목적으로, Electrokinetic(EK) 기법을 적용 할 때 지반 내에서 pH와 오염물 분포특성을 알아보았다. 시료 내에서의 EK 처리로 인한 납 제거 효과를 살펴본 결과 1V/cm의 전압경사 하에서 납은 음극으로 이동하여, 전극 간 시료의 80%정도 영역에서 제거율은 대략 75% 정도에 이르렀다. 그러나 이동된 납은 대부분이 음극영역에 침전되어 궁극적으로 음극수로 배출되어 제거되는 납의 양은 미미하였다. 이때, EK 정화처리는 시료의 대부분인 80% 정도에서 토양환경보전법 상의 규준치를 만족할 수 있으나, 음극쪽 20%지역은 별도의 향상기법을 적용하여 처리하는 기법이 필요하다.

  • Enormous volumes of mining wastes from the abandoned and closed mines are disposed without a proper treatment at Southeastern part of Kangwon Province. Erosion of these wastes contaminates soil, surface water, and sediments with heavy metals. Objectives of this research were to fractionate heavy metals in the mine waste and to assess the potential S. P. A. G.(Soil Pollution Assesment Guidance) of each metal fraction. Mine wastes analyzed for physical and chemical properties. pH of wastes ranged from 3.3 to 8.0. Contents of total N and loss on ignition matter were in the ranges of 0.2~5.6%, and 0.8~15.3%, respectively. Heavy metals in the wastes were higher in the coal mines than those in the other mine wastes. Total concentrations of metals in the wastes were in the orders of Pb > Zn > Cu > Cd, exceeded the corrective action level of the Soil Environment Conservation Law and higher than the natural abundance levels reported from uncontaminated soils. Relative distribution of heavy metal fractions was residual > organic > reducible > carbonate > adsorbed, reversing the degree of metal bioavailability. Mobile fractions of metals were relatively small compared to the total concentrations. Soil Pollution Assesment Guidance(SPAG) values were ranged from 0.08 to 9.14 based on labile fraction of metal concentrations. SPAG values of labile concentration were lower than those of total concentration.

  • 지하수의 보전 보호를 위한 정책 중 가장 중요한 것이 지역적으로 지하수 보전구역을 지정하여 관리하는 것이며, 지하수 보전구역은 지하수법(제12조)에 의하여 지하수 보전지구와 개발제한지구로 분류되어 관리하도록 규정되어 있다. 금번연구에서는 GIS(지리정보시스템)을 이용하여 서울시 지하수 분류도를 먼저 작성한 후 가장 수질이 양호한 1급 및 2급 지하수 대창지역(상류의 지하수 함양지역이나 유일 대수층지역 등)을 지하수 보전지구의 우선 대상지역으로 선정하였으며, 지하수분류는 건설교통부(2000)에서 제시한 지하수의 현재 수질상태, 음용수원으로서의 현재 및 장래 이용성, 기초 수리지질특성, 각종 지하수오염유발행위.시설 소재여부 등에 따라 4등급 분류방법을 기본으로 하였다. 작성된 지하수 분류도에서 1차 선정된 서울시 지하수 보전지구 우선 대상지는 약 57,1$\textrm{km}^2$(서울시 전체면적의 약 9.4%)로 나타났으며, 보전지구의 최종 지정을 위해서는 대상지역에 대한 지하수 정밀조사가 필요하다. 또한 지하수 보전지구의 관리방안도 제주도(2000)와 건설교통부(2000)의 지하수 보전관리계획을 참조하여 서울시에 적합한 안이 마련되었다.

  • For 63 soil series distributed in Jeju Island, natural uncultivated soils in each soil series were collected, and their physicochemical properties and their concentrations of 19 heavy metals including 8 heavy metals which are regulated by Korean Soil Environment Conservation Law, were analyzed. Moreover, the correlations between physicochemical properties and heavy metal concentrations, and between heavy metal concentrations were analyzed. The heavy metals distributed in the higher concentrations and the lower concentrations with arithmetric mean value, were Mn(730 mg/kg) and Ba(493 mg/kg), and Hg(0.146 mg/kg) and Tl(0.096 mg/kg), respectively. The correlations between pH($H_2O$) and heavy metals(Hg, Ni, Co, Se), between pH(NaF) and heavy metals(Hg, Ba, Se, Tl), and between organic matter content and heavy metals(Hg, Tl) were significant at the 0.01 level. From the correlations between heavy metal concentrations, there were 22 where there were significant at the 0.01 level and they showed positive correlation. Among those, the heavy metals showing the correlation higher than r=0.5, were Sb-V(0.878), Mo-Sn(0.867), Co-V(0.654), Co-Sb(0.648), Be-Sn(0.546), and Sn-Tl(0.528).
