dc.description.abstract The objective of this work was to propose detailed methodologies for improving coherence between soil and groundwater standards. To achieve this objective, firstly, we reviewed existing soil and groundwater quality standards (including cleanup standards) of other countries and investigated detailed methodologies for relating soil standards to groundwater ones. We found that most countries set up soil cleanup standards in order to protect groundwater. So, they are taking into account simultaneous soil and groundwater contamination phenomenon. Since the USA and Netherlands are adopting a risk-based approach, called Soil Screening Guidance (SSG), to improve coherence between soil and groundwater standards. This approach seems reasonable to apply for Korea therefore, we adopted this methodology. After revising values of important parameters with Korean soil and hydrogeologic characteristics data, we applied the SSG methodology to identify coherence between soil and groundwater standards. We found that current soil quality (cleanup) standards were not coherent with groundwater quality (cleanup) standards or drinking water standards. Through the sensitivity analysis for soil screening levels, we found that a nationwide dilution-attenuation factor (DAF) value, which can explain reasonably the contamination phenomena in Korea, should be determined to calculate more realistic soil quality standards. Especially, the soil related parameters (e.g., organic carbon content, bulk density, and volumetric water content) affected greatly the soil screening levels (SSLs) for organic contaminants (not inorganic contaminants), indicating that we need to characterize the nationwide soil related parameter values. Furthermore, through several numerical simulations, we found that the DAF equation proposed by the U.S. EPA may not be appropriate for hydrogeologic characteristics of Korea, possibly due to very thin surficial aquifer depth in Korea. We believe that the following researches should be pursued further in order to develop the SSG procedure appropriate to Korea. Firstly, nationwide-, regional-, and local-scale DAF values (or maps) need to be determined through comprehensive surveys for hydrogeologic characteristics. Secondly, since groundwater pumped from rock aquifer is usually used in Korea, the DAF equation appropriate to rock aquifer needs to be developed. Lastly, parameters related to Korean soils need to be newly investigated or complied from existing data. These data are very important for setting up soil standards, especially for organic contaminants. -

dc.description.bibliographicalintroduction 본 연구는 우리나라 토양 및 지하수환경기준의 연계성을 강화하기 위한 구체적인 방법론을 제안하고자 하였다. 이를 위해 우선 외국에서는 어떻게 토양 및 지하수환경기준을 연계하고 있는지, 그리고 그 구체적인 방법론(들)이 무엇인지를 문헌조사를 통해 알아보았다. 대부분의 경우 토양 및 지하수의 동시오염현상을 고려하였고, 지하수를 보호하기 위해 토양정화기준을 설정하고 있었다. 미국과 네덜란드에서는 위해성에 근거를 둔 접근법(Soil Screening Guidance, SSG)을 이용하여 토양 및 지하수기준의 연계를 강화하고 있고 우리나라 상황에도 적용 가능하다고 판단되어, 본 연구에서는 SSG 방법론을 적용하였다. 우리나라 토양 및 수리지질학적 자료를 이용하여 SSG를 적용한 결과, 현재의 토양환경(정화)기준은 지하수환경(정화)기준 또는 먹는물수질기준과 연계되어 있지 않은 것으로 나타났다. Soil Screening Levels (SSLs)에 대해 민감도 분석을 실시한 결과, 토양환경기준을 좀 더 현실적으로 수립하기 위해서는 우리나라에 적합한 희석-감쇄인자(dilution-attenuation factor, DAF)를 설정하는 것이 필요하다고 판단되었다. 특히, 토양관련매개변수(예를 들면 유기탄소함량, 용적밀도, 수분함량 등)는 유기화합물 SSLs에 크게 영향을 미치는 것으로 나타나 이에 대한 전국적인 자료 조사 또는 특성화가 필요한 것으로 판단되었다. 수치모델링을 통해선, 미국환경청이 제안한 DAF공식은 우리나라의 수리지질학적 특성, 즉 깊이가 매우 얕은 표층 충적대수층에는 적용하기 힘들다는 것을 알아내었다. 따라서 우리나라에 적합한 SSG방법론을 개발하기 위해서는 아래와 같은 연구가 추후에 수행되어야 할 것으로 판단되었다. 우선 수리지질학적 특성에 대한 광범위한 조사를 통해 전국적/지역적/국지적인 규모의 DAF값(또는 도면)을 구할 필요가 있다. 또한 우리나라의 경우 암반대수층으로부터 지하수를 개발하는 경우가 많으므로 이에 적합한 DAF공식을 개발할 필요가 있다. 그리고 우리나라 토양특성에 대한 광범위한 조사를 새로이 실시하거나 기존 문헌으로부터 체계적으로 수집할 필요가 있다. 이는 (특히 유기화합물에 대한) 토양환경기준을 설정하는데 매우 중요하기 때문이다. -
