  • The oil spill accident near Goeje Island on April 3, 1997 was analyzed using two RADARSAT SAR images. The first scene was acquired 3 days after the accident as an extended low beam mode and the second scene was acquired 12 hours after the first scene as a standard beam mode. The two scenes showed slicks not only by oil spills but also by oil spill look-alikes caused by wind sheltering, low wind, natural film, and etc. These slicks were analyzed and classified, and natural films produced from aquaculture farms around Goeje Island were also suggested as a strong candidate for slicks on SAR images. The study with two SAR imags indicated the oil spill patterns which spreaded to the southwest immediately after the accident and switched the direction to the east. The spreading patterns shown in two SAR images also showed good agreement with in-situ observations.

  • Soils contaminated with hydrocarbons and residual metals can be effectively treated by soil washing. In developing the soil washing process several major effects for separating contaminants from coarse soils progressively improved upon combinations of mining and chemical processing approaches. The pilot-scale soils washing process consists of the four major parts : 1) abrasive scouring, 2) scrubbing action using a washwater that is sometimes augmented by surfactants or other agents, 3) rinsing, and 4) regenerating the contaminated washwater. The plant was designed based upon the treatment capacity > 5 ton/hr on site. The lumpy contaminated soil fractions first experience deagglomeration and desliming passing through a rolling mill pipe. In the second unit the attrition scrubbing module equipped with paddles uses high-energy to remove contaminants from the soils. And a final rinsing system is assembled to separate the washwater containing the contaminants and very fine soils from the washed coarse soils. For recycling the contaminated washwater passes through a washwater clarifier specifically designed for flocculation, sedimentation and gravity separation of fine as well as flotation and separation of oils from the washwater. In order to more rapidly assess the applicability of soil washing at a potential site while minimizing the expense of mobilization and operation, a mobile-type soil washing process which is self-contained upon a trailer will be further developed.

  • With the rapid development of oil and chemical industry in the late 20C, massive transportation of oil by oil tanker vessel has grown and it caused the big oil pollution accidents. When oil spill from the oil tanker, damages reach into the astronomical figures in economically and damages affect wide area and many people with break the balance of ecosystem. Recently in Korea, the oil pollution accidents has occurred frequently as growing of oil consumption and it caused large-scale damages to the victim. Oil pollution in Korean offshore takes not only korean fishermen from their life ground and break the ecosystem but it takes too much time and money to recover. To minimize oil pollution damages, it is necessary to make pre-caution effort as a ship owner and relevant government bodies should endeavor to prevent from more damages. But once oil pollution accidents occurs in territorial sea, compensation for victim fishermen is very important. But it is true that compensation is not paid to victim smoothly. So this study aims at the problems of oil pollution compensation to the Korean victim and find the best way to get reasonable compensation.

  • After the Sea Prince oil spill accident in 1995, the korean government has taken a measure to establish an emergency response system and equip clean-up capacity against large spill, major contents of which are as follows: First, Korea Marine Pollution Response Corporation has been established as a non-government organization for recovery of spilled oil in order to improve private response capabilities. Second, clean-up equipments, such as large clean-up vessels and oil fences for the open sea operation has been expanded. Third, a national contingency plan on the large spill accidents has been established compliance with the provisions of Article 6 of the OPRC 1990. However, there exist some problems in the national response system, such as clearly roles definition between government and private agencies; propel amendment of the Marine Pollution Prevention Act to incorporate major contents of the OPRC 1990; and training and exercises of clean-up personnel. With the above problems in mind, this paper reviews the current issues on the national oil pollution response system and recommends policy-making to tackle to those problems.

  • Soil contamination with petroleum oil around a military army was investigated. It showed that soils of a riverside highland, an entrance of the military army, and nearby roads were contaminated with total petroleum hydrocarbons (TPH) released from the military army to the depth of approximately 2 m. The measured concentrations were as high as 15,277 mg/kg. A wide range of soil in the riverside highland was contaminated by the movement of oil to the surface soil, which occurred with the vertical movement of groundwater table caused by the change of river water level and groundwater level. Spilled petroleum oil components were released into Wonju Stream by the increase of hydraulic conductivity and the groundwater flow.
