질산성질소 및 탁도로 오염된 지하수공에 대하여 환경성 복원을 위한 오염방지 시설을 시범 설치하였다. 지하수공에 대한 오염 정도를 조사한 결과 PS-1, CW-1, 그리고 CW-2 공이 질산성질소로 오염되어 먹는물 수질기준을 초과하였고, CW-3 공은 탁도가 먹는물 수질기준을 초과하였다. 오염원은 지하수공 개발시 수량 확보를 위하여 그라우팅을 제대로 하지 않은 불량시공으로 인한 오염된 지표수의 유입으로 기인되었다. 금번 연구는 오염된 지하수의 환경성 복원을 위한 것으로, 오염원과 지하수를 격리시켜 오염물질의 지하수 내 유입을 방지할 수 있도록 패커 그라우팅을 완벽하게 다시 실시하였으며, 오염방지시설을 설치하였다. 이 연구를 위하여 먼저 대수층의 분포 및 특성팍악, 지하수공내 지표수의 유입구간 규명, 지하수 오염원, 오염실태, 오염경로 등을 파악하였다 오염방지시설을 설치한 후, 설치 전,후의 질산성질소와 탁도의 함량을 비교하기 위하여 수질 분석을 실시하였다. PS-1의 경우, 오염방지시설 설치전의 질산성질소 함량은 16.1 mg/L 이었으나, 설치후에는 8.1 mg/L, 7.9 mg/L로써 설치전에 비하여 51% 감소되었으며, CW-1은 10.3 mg/L에서 6.3mg/L으로 39%, 그리고 CW-2는 14.9 mg/L에서 9.0 mg/L 으로 40% 감소되었다. CW-3 공의 탁도는 157 NTU에서 0.97 NTU로 완벽하게 복원되었다.

The purpose of this research is to select an appropriate location of water pollution prevention facilities(WPPF) through evaluating location decision factor using environmental geographic information system. To do that, this research reviewed the current location policies of WPPFs and its related researches. And this paper builds water pollutant statistical databases, integrated them with the geographic information system of the administrative areas where water pollutants are generated, and gears it with statistical programs such as correlation and regression analysis in order to figure out the pollution factors which influence on the location decision of WPPF on the real time base. The volume of discharge of industrial wastewater is one of the most important water pollutants on the location decision of WPPF. And the number of industrial facilities also was the most important location decision factor in constructing the WPPFs. In addition, this paper noted that the number of population in each area makes a role to restraint the construction of WPPF. It identified that the disposal facility in Nackdong river upper-middle watersheds was insufficient in treating the livestock pollutants. Therefore, Gyeongbuk should concentrate on the construction of disposal facilities of livestock pollutant in these areas. The results of this research will contribute to decide what kinds of WPPF should be constructed on which watershed in Nackdong River, and to forecast the future water quality of each watershed.

일반세균, 질산성질소, 탁도로 오염된 지하수 관정의 2개공에 대해 수질개선을 시행하였다. 그 결과 2개공 모두 음용수 기준에 적합한 수질개선 효과를 가질 수 있음으로 하여 수질오염 발생의 주요 요인 중의 하나가 지하수 지표하부 오염방지 시설인 그라우팅이 부실함으로써 기인함을 규명할 수 있었다. 따라서, 본 연구를 통해 수질이 오염된 지하수 관정의 수질개선이 가능하다는 확인은 물론 또한, 지하수 관정내 지표수의 유입을 방지하기 위해서 지하수 상부오염방지 시설의 설치가 적극적으로 추진되어야 할 것이다. 지하수 오염을 예방하기 위해서는 지하수 개발 단계에서부터 지하수 지표하부 오염방지 시설이 연암 암반층까지 견실하게 적용되어져야 한다는 것을 확인할 수 있었다.

최근 고속도로의 연장과 고속도로 이용객의 증가에 따라 휴게소 및 고속도로에서 발생하는 폐기물의 양이 점차 증가하고 있다. 고속도로 휴게소의 지리적 여건상 발생하는 폐기물을 매립하기가 어려워 재활용 폐기물을 제외한 나머지는 전부 소각에 의존하고 있는 실정이다. 또한 고속도로 휴게소나 지사는 대부분 소형 소각로가 설치되어있어 오염방지시설이 제대로 설치되지 않고 가동되고 있다. 과거 소형 소각로는 대기오염 규제대상에서 제외되었지만 법률이 개정되어 25kg/hr 이상 소각시설이 대기오염물질 배출시설로 규정됨에 따라 기존의 소형소각시설도 대기오염방지를 위한 대기오염방지 시설을 설비하여야 한다.

The practices of the construction and management of the petroleum and hazardous chemical compound storage facilities in Korea were investigated extensively, and the problems were identified. The advanced technologies in the U.S.A were comparatively studied. Considering the effectiveness of leak prevention and applicability, the following measures were suggested. To prevent corrosion of a tank, a clad tank, an interior lining tank, or a double-wall tank were thought to be the most cost effective. For piping. use of non-metalic materials was suggested. A catchment basin seemed to be effective for preventing spills. For monitoring of leaks, constructions of more than one of detection systems, such as an automatic leak detection device. a vapor detection system, a groundwater monitoring system, or a double-wall monitoring system, were recommended.

Marine pollution prevention manager system has been operated for the purpose of preventing marine pollution from ships and marine facilities in Korea. As a new "marine environment management act" replacing an old "marine pollution prevention act" had entered into force from January 20. 2008. the works and business of the education and training courses for marine pollution prevention manager are scheduled to transfer from KIMFT(Korea Institute of Maritime and Fisheries Technology) and FHRDI(Fisheries Human Resource Development Institute) to KOEM(Korea Marine Environment Management Corporation) on January 1. 2011. The present state of the education and training for marine pollution prevention managers of marine facilities was surveyed and analyzed in order to prospect trainee demands for the education and training and to provide KOEM with basic data for establishing a new system for the education and training. The existing education and training courses of FHRDI for marine pollution prevention manager of marine facilities have been conducted as a regular course of 21 classes for 3 days. The average annual number of trainees in FHRDI for 6 years from 2003 to 2008 was 187 persons and the annual number of trainee was 202 persons in 2008. The trained demands for the education and training are expected to increase sooner or later, depending major factors such as the extension of fields and ranges for marine facilities and marine environment management business due to the enforcement of new "marine environment management act".

The purpose of this study is to find the reality of environmental management cost in construction projects and to suggest some policies in order that owners appropriate the environmental management cost reasonably in the construction budget for reducing the environmental pollution at job sites. We surveyed the actual state of appropriating and expending the environmental management cost over 122 construction sites. According to the results of the survey, while the appropriated rate of the environmental management cost was 0.59% of the total construction cost. the expended rate reached at 0.94%. When examining the antipollution facilities which were operated in job sites, the investment for equipment against air-pollution such as tire washer, dust-proof device was relatively higher than other antipollution equipment. As the method appropriating the environmental management cost, we concluded that a quantity-per-unit costing method is more reasonable than appropriating at a fixed rate of total construction cost considering that there is little correlation between total construction cost and the environmental management cost. To do so, antipollution facilities that must be examined at a design or estimation stage of a construction project should be prescribed by the law. Moreover, referenced cost data for the quantity-per-unit costing should be prepared and officially published.
