The solid waste incineration facilities which cause environmental pollution. And those are some kind of loathing facilities for residents who do not want it. This problem could be solved by location feasibility study. The purpose of location feasibility study was to determine one site out of three candidate sites. This study which was done by the law, environmental and economic factor was considered for optimum site selection. Comparative evaluation among the candidate sites was done by ordinal scale and thus the optimum site was selected.

LHR(Landfill Site Hazard Ranking Model) was developed for ranking the relative hazard of landfill sites by using the method of value-structured approach. LHR consists of combining a multiattribute decision-making method with a Qualitative risk assessment approach. A pairwise com parisian method was applied to determine weights of landfill site factors related. To determine the hazard of landfill site, hydrogeological factors, waste characteristics factors and receptors factors were evaluated by LHR. LHR can help decision-makers prioritization of remediation of landfill sites through the relatively convenient and concise evaluation method of landfill site features related. LHR focuses mainly on pathways of groundwater and surfacewater for evaluating landfill hazard to receptors including humans. To validiate the applicability of LHR, Nanjido Landfill site, Metropolitan Landfill site, and Hwasung Landfill site were evaluated.

Exposure assessment methodology for outdoor air inhalation pathways (i.e., inhalation of volatile compounds and fugitive dust in outdoor air) was investigated. Default values of several parameters currently used in Korea (e.g., Q/C; inverse value of concentration per unit flux, and frs; soil fraction in PM10) may not be suitable and lack site-specificity, as they have been adopted from the risk assessment guidance of the United States or the Netherlands. Such limitation can be addressed to a certain degree by incorporating the volatilization factor (VF) and the particulate emission factor (PEF) with Box model. This approach was applied to an exposure assessment of a site contaminated with petroleum hydrocarbons in Korea. The result indicated that the suggested methodology led to more accurate site-specific exposure assessment for outdoor inhalation pathways. Further work to establish methodology to determine site-specific Q/C values in Korea needs to be done to secure the reliability of the exposure assessment for outdoor air inhalation pathways.

The comparative evaluation is the most effective method for site selection because the selection of waste treatment facility is to determine the optimum site out of limited candidate sites. This study adopted the ordinal scale evaluation, one of methods of comparative evaluation. The ordinal scale evaluation aims to determine the investigating items referring to the character of sites, to determine the importance factors for investigating items, and to determine the optimum site according to the quantitative evaluation. As a result of this study, the defects of the former reports on the environmental characteristics, such as obscurity of meaning and subjective statement, were reduced by the ordinal scale evaluation which is one of the quantitative evaluation methods. This ordinal scale evaluation method has some valuable advantages, such as, to be able to consider the cost-effect efficiency, to consider the objectiveness and the clearness of the reports on the environmental characteristics. Therefore the reducement of social complications about site selection of the indisposed facilities could be expected by this study.

As the development of total management systems for sites along with site environmental information is becoming standard, the system known as the Site Information and Total Environmental database management System (SITES) has been developed over the last two years. The first result was a database management system for storing data obtained from facilities, and a site characterization in addition to an environmental assessment of a site. The SITES database is designed to be effective and practical for use with facility management and safety assessment in relation to Geographic Information Systems. SITES is a total management program, which includes its database, its data analysis system required for site characterization, a safety assessment modeling system and an environment monitoring system. It can contribute to the institutional management of the facility and to its safety reassessment. SITES is composed of two main modules: the SITES Database module (SDM) and the Monitoring & Assessment (M&A) module [1]. The M&A module is subdivided into two sub-modules: the Safety Assessment System (SAS) and the Site Environmental Monitoring System (SEMS). SAS controls the data (input and output) from the SITES DB for the site safety assessment, whereas SEMS controls the data obtained from the records of the measuring sensors and facilities. The on-line site and environmental monitoring data is managed in SEMS. The present paper introduces the procedure and function of the M&A modules.

최근 국내에서는 외국기업의 국내진출에 따른 M&A, 미국과의 자유무역협정에 따른 시장개방에 따라 부지환경평가 (토양환경평가)의 결과를 반영할 필요성이 점차 증가되어 왔다. 따라서 이 연구에서는 연안매립지역에 위치한 대규모 화학공장부지에 대한 실제적인 부지환경평가를 통하여 국내의 토양환경평가 지침의 문제점을 보완하고 효율적, 경제적 평가를 위한 복합적 조사기법들을 이용하였다. 이 연구는 기초조사, 부지현황조사, 시료채취와 분석, 관측정 설치와 수리지질 조사, 자료 분석의 6단계로 진행되었다. 각각의 조사단계에서는 기존자료조사, 선구조분석, 지표지질조사, 지구물리탐사, 시추조사, 수리전도도, 지하수의 유향유속측정, 시료채취 및 분석 결과를 조합하여 복합적으로 해석하였다. 연구결과, 부지환경평가를 위한 이러한 다양한 조사기법들의 적용은 부지의 오염현상, 지하매질에 대한 부지특성화에 매우 효과적이었다. 국내에서는 '토양환경평가 지침'에 의한 기초조사에 있어 기존자료의 이용, 가용한 자료의 보관상태, 평가를 위한 관계자 인터뷰 등에 있어 매우 열악한 여건을 가지고 있다. 따라서 '부지환경평가'를 수행하는데 있어 이러한 복합조사기법의 적용은 더욱 경제적이고 효율적이며, 토양과 지하수오염을 연계하여 평가하는데 있어서도 매우 유용할 것으로 기대된다.

Most of the solid waste has been land-filed as an ultimate disposal method in Korea, with might induce many environmental problems by generating odor, particulates and leachate. The landfill site should be considered as a kind of pleasant facility to neighboring residents. Currently, for a landfill site, while the environmental law requires to perform the EIA before the planning. EIA has been performed after the selection of the landfill-site. That might be controversal to the purpose of doing EIA. In this study, the weakness of the EIA for the landfill-site was analysed and was suggested for comprehensive EIA in Korea as well.

The Environmental Site Assessment System(ESAS) in Korea which became effective as of 2002 is very similar to the ASTM standard practice in United States. Unlike the United States, however, we do not have Phase I ESA, enough environmental professionals with approved training and practical experiences, and detailed guidelines for a governmental action. As a result of comparison the ESAS with the ASTM standard practice, the ASTM standard practice is focused on the Innocent Landowner Defense and has a difference in data search process as well as legal and methodological ways from the ESAS. Therefore, the Transaction Screen Process in ASTM E-1528 standard practice is suggested to reduce the risk potentially produced under on-site assessment and to achieve efficient on-site assessment. In addition, social and executive supports are discussed to more activate on-site assessment. In near future this study is expected to be standardized more in detail with activation of on-site assessment and it is also expected to increase the role and responsibility of environmental professionals considerably.

To assess preliminarily the contamination potential of water resources including groundwater owing to the hydrogeological characteristics of landfill site and the potential impact to humans and animals through contamination of water resources by leachate, "Landfill Site Preliminary Assessment Model(LASPAS)" was contrived. LASPAS could help them proritization of remediation of landfil sites by the convenient and relatively simple evaluation method of landfill site features. LASPAS was designd to aliot numerical ratings to landfill site related factors undermentioned; 1) hydrogeological factors such as hydraulic conductivity of aquifer, thickness of confining layer over aquifer, topographical slope, net recharge, and subsurface containment 2) water resources contamination factors of impacts on receptors such as proximity to drinking water supply, substitutability of drinking water supply, type of use of water resources, known impact on drinking water supply, and flood potential.

Analysis of carrying capacity and site suitability by the systematic application of environmental information an provide a basis for implementing environmentally sensitive and sustainable resource development policies. Based on the availability of public services and environmental and site-specific constraints, a Rural Residential Density Matrix was applied in Santa Cruz County, California, USA to assess the development potential of rural land parcels since 1980. In one case, the Matrix was applied to calculate the allowable development density on a site in Lompico planned for use as a Buddhist retreat center. These calculations revealed higher environmental sensitivity and lower carrying capacity than projected in the proposed plan. Under the constraints of the county's minimum acreage policies and insufficient developable land, the developer cancelled the proposed plan. This example suggests that application of the Matrix at the concept development stage would increase the effectiveness of the prior environmental review and environmental impact assessment (EIA) system in Korea.
