inducing each business to make efforts for production process improvement by analyzing and managing water pollution levels. A reasonable and objective effluent charge is determined in order to improve policy credibility by identifying the exact pollution level for each period of time. Technical support and consultation for the establishment of control methods for the pollutants discharged by a business are provided, through the continuous assessment and analysis of the pollution level by the remote control of water quality. Soil Soil pollution is different from other environmental pollution in that it is almost impossible to detect soil contamination by eye. Such pollution cannot be recognized until it has progressed to a certain level, and there is a long time delay between the pollution activity and the onset of damage. In addition, the effect of soil pollution is very long-lasting. Once soil is polluted, it is hard to remove the pollution; it takes a great deal of time and expense. Soil goes through three phases: solid, liquid and gas. The solid phase consists of inorganic material from stone weathering, dead bodies of animals and plants, and organic materials of living organisms. The liquid phase refers to soil water. The gas phase refers to soil air. Though soil comes from stone weathering, it takes various forms such as clay, silt, sand, and gravel, depending on the mineral compositions of rocks and metamorphic processes. Soil performs numerous environmental functions, including flood prevention, water containment, water purification, landslide prevention, erosion prevention, pollutant filtering, regulation of surface temperature and humidity, and protection of living organisms and vegetation. Seventeen materials are designated as soil pollutants in Korea according to the Soil Environment Conservation Act, including cadmium, copper, arsenic, mercury, oil, and organic solvents. Each material is subject to two standards: one represents a pollution level that could negatively affect people's health and property and the growth of animals and plants; the other is for soil pollution countermeasures where pollution exceeds the standard and actually harms people's health and property and the growth of animals and plants. Soil pollution standards classify soil by its various uses in accordance with the Cadastral Act. That is, farms and woodlands that are less likely to be polluted are classified as 'Ga' areas; factory sites, roads and railway sites that are more likely to be polluted are classified as 'Na' areas. Soil is mainly polluted by human activities, production activities in agriculture
