The integrated solid waste management for Seoul Metropolitan city can be established on the basis of the following hierarchy of priorities: 1. Efforts for source reduction should be propelled by both government and citizens to achieve the effects of resource conservation. The adequate production and consumption which are environmentally amenable and sustainable can be induced by the reasonable imposition of deposit money for waste treatment to one-time use products. To accomplish source reduction effectively, the induction of legal and institutional regulation of producer and consumer participation is requisite. 2. For resource recovery, wastes generated should be recycled as far as practicable. Community residents are responsible to separate discharge, the authorities concerned have responsibility of separate collection, and recycling industry should be assissted through tax reduction and financing. Resource separation facilities can be constructed at Kimpo Metropolitan landfill site for wastes not separately collected due to some unavoidable circumstances. 3. Garbage should be composted. Garbage is uneconomical for incineration, because it has high moisture content and low calorie, thus there is no reason for the incineration of garbage even though garbage is classified into combustibles. Composting facilities can be located at sites which are not densely populated and easily accessible to transportation, for example, Kimpo Metropolitan landfill site. Compost produced can be managed by the authorities for the use of fertilizer to a green tract of suburban land and farms. 4. Nonhazardous combustible wastes not recyclable can be utilized for thermal recovery at the incinerators which are completely equipped with pollution control devices. According to the trend of local autonomy and the equity principle of local autonomous entities, incineration facilities of minimal capacity required can be constructed at each districts of Seoul Metropolitan city which have organized local assembly. In case of Yangcheon district, the economically combustible waste quantity is about 260 tons/day which exceeds 150 tons/day, the incineration capacity of existing facility. But, from now on, waste quantity can be reduced substantially by the intensive efforts of citizens for source reduction and recycling and the institutional support of administrative organizations. Especially, it is indispensable for the government to constitute institutional and technological bases that can recycle paper and plastics form 43% of waste generated. A good time for constructing of incineration facilities for municipal solid waste can be postponed to the time that pollution control technologies of domestic enterprises are fully developed to satisfy the standards of air pollution prevention, because the life expectancy of Kimpo Metropolitan landfill site is about 25 years. Within this period, institutional improvements and technological advancements can be attained, while the air qual. ity of Seoul Metropolitan city can be ameliorated to the level to afford incineration facilities. 5. For final disposal, incombustibles and ash are landfilled sanitarily at Kimpo Metropolitan landfill site.

Analysis of hydrological safety as well as the determination of many substance concentrations are necessary when bioreactor systems are introduced to landfill operations. Therefore, hydrological and substance balance model was developed since it can be applied to various bioreactor landfill operation systems. For the final evaluation of the model's effectiveness, four different methods of injections (leachate alone, leachate and organic waste water, leachate and reverse osmosis concentrate, and all the above three combination) was applied to 1st landfill site of Sudokwon landfill. As a result, the water content of the hypothetical cases for four different systematic bioreactors is projected to be increased up to 35.5% in next 10 years, and this indicated that there will be no problems in meeting the hydrological safety. Also, the final $Cl^-$ concentration after 10-yr time period was projected to be between from minimum 126 to maximum 3,238 mg/L, which could be still a decrease from the original value of 3,278 mg/L. According to the proposed model, whether the substance concentration becomes increased or decreased largely depends on the ratio of initial quantity of inner landfill leachate and the rate of injection.

부산 석대 생활폐기물 매립지는 1987년 6월부터 1993년 5월까지 만 6년간 사용된 중간규모의 매립장이다. 매립장에 분포하는 안산암질암과 유문암질암에는 절리와 단층이 발달되어 있다. 1996년 7월과 1997년 6월에 2차에 걸쳐 침출수, 하천수 및 지하수의 수질을 조사한 결과 침출수와 하천수의 수질은 농도가 약간 감소되었으나, 지하수 수질은 더 악화되었다. 석대매립지의 지하수 오염은 충적층에 개발된 천층지하수는 물론이고, 150m 심도의 암반지하수들도 오염이 심화되어 있다. 침출수에 의한 지하수 오염범위는 매립장 경계에서 서쪽으로 약 500 m 정도, 남쪽으로 약 1 km 정도 까지이다. 석대 매립지 주변 수질의 오염제어를 위해서는 매립지 일윈에 감시정 및 채수정의 개발, 침출수처리장 건설, 기존의 지하 차수벽시설 보완작업 등이 필요하다.

본 연구에서는 매립완료후 6년 경과된 매립지 내 물리적 조성, 총고형물, 수분, Gas분석 등을 통하여 비위생 매립지의 안정성을 평가하였다. 폐기물의 물리적 성상을 조사한 결과, 가연성 물질은 23.64%, 불연성 물질 76.36%를 차지하며, TS, VS, FS는 각각 77.69%, 74.24%, 25.75%를 차지하고 있다. $CH_4$농도는 전체평균 4.5%로 매우 낮은 값을 나타내고 있는데 이는 매립된 쓰레기 중 $CH_4$ 가스 생성 원인이 되는 생분해성 유기성분들이 모두 분해되어 안정화되었기 때문인 것으로 판단된다. $CO_2$의 농도 또한 평균 15%로 낮아 이 역시 매립된 쓰레기가 매우 안정화되었음을 의미하며, 매립지에서 환경적인 영향을 미치지는 않을 것으로 예상된다.

바이오리액터형 매립지는 매립지 내부로 침출수나 폐수 같은 수분의 공급을 통하여 폐기물의 분해를 촉진하기 위하여 운영하며, 이러한 수분 공급은 매립가스를 증산하고 결국 매립지 조기안정화에 기여한다. 최근 바이오리액터형 매립지 운영을 위한 환경법이 제정되었으며 이에 따라 국내 최초로 수도권매립지에 도입하였다. 바이오리액터형 매립지의 안정적인 적용을 위하여는 매립지 내부의 수분분포 파악이 필수적이며 이를 통해 해당 구역에 적정하게 수분이 유지되도록 한다. 이를 위하여 매립지내부 수분분포 파악을 위하여 전기비저항탐사를 실시하였다. 본 연구에서는 수도권매립지 제2매립장 내에 침출수 재순환과 함께 장기간 전기비저항탐사를 수행하였다. 그 결과, 전기비저항값이 계절적 온도 변화에 큰 영향을 받고 있는 것을 확인할 수 있었다. 이에 따라 본 연구를 통해 조사된 온도와 전기비저항값의 상관관계를 통한 보정방법을 이용하여 바이오리액터형 매립지를 안정적으로 운영할 수 있도록 하였다.

A geophysical and geochemical study was performed to verify the depth of landfill as well as the horizontal/vertical distribution of leachate at the landfill site located in Gongju. The electrical resistivity, with dipole-dipole array and dipole spacing of 5m, was applied along the nine survey lines and electromagnetic induction survey was conducted along the perimeter traverse surrounding the landfill. Cations, anions and stable isotope ($\delta$D and $\delta$$^{18}$ O) analyses were performed on about 63 water and leachate samples collected in dry and rainy seasons at 31 sites. The result of electromagnetic induction survey make it possible to derive the potential route of leachate in the past or present. The imaging of processed resistivity field data show that the possible route of leachate doesn't exist except the survey line 7. The weak zone traversing the landfill, however, is revealed by the electrical resistivity imaging, which may be the potential route of leachate toward the deep ground. The geochemical data agree well with geophysical data for deducing possible route of leachate of the site.

For the purpose of saving the waste disposal cost a self-governing community on the whole reclamates the wetland and uses it as a landfill site. During the operation period of site, the environmental impact by the leachate is usually neglected. Therefore, to predict the environmental impact and dispersion of leachate, the wetland adjacent to the South Han River in Chungju is selected as a site of case study. The main content of this article is to apply the simulation model CONMIG to leachate transfer in the ground water and to derive the impact by the leachate. A kind of non-reacting conservative material, chloride ion is used as a tracer to quantify impacts by the leachate.

토양 및 지하수의 오염이 사회적으로 심각한 문제로 대두되면서, 복원대책을 위한 조사 방법으로서 물리탐사 기술이 도입되고 있다. 최근의 물리탐사 기술은 컴퓨터를 비롯한 디지털기술의 발달에 힘입어 측정 및 해석기술이 발전함에 따라 짧은 시간에 대량의 데이터를 취득할 수 있으며, 신뢰성이 높은 해석결과를 얻을 수 있게 되었다. 또한 지반 가시화 기술로 탐사결과를 보다 알기 쉽게 영상화할 수 있게 되어, 오염지반의 조사뿐만 아니라 정화과정의 모니터링 등에 널리 사용되고 있다. 본문은 쓰레기 매립지를 대상으로 전기비저항탐사 및 전자탐사를 실시하고, 탐사결과를 이용하여 매립지의 오염특성 평가를 위한 물리탐사의 적용성에 대해서 검토했다. 그 결과 전기비저항탐사 및 전자탐사를 통하여 매립장내의 오염분포 및 침출수의 유동경로 등에 유용한 정보를 얻을 수 있었다.

This paper estimates the long-term settlement of In-cheon unsanitary solid waste landfills. which is 20 years old. The unsanitary solid waste landfills was subjected to pre-loading system over a period of 1 year, and the settlement for 300 landfill monitors provided measured data. This landfill contain relatively small amount of organic component, therefore the initial stage of settlement was very small. The existing settlement models are examineed to compare with the observed behavior of this site and, also to estimate long-term settlement. The Hyperbolic, Bjarngard & Edgers, and Power Creep Law models showed good agreement well with the measured settlement of the In-cheon unsanitary solid waste landfills.
