Abstract
TOC environmental standard was established to understand the pollution level accurately and to improve the water quality. It was found that the relationship between COD and TOC showed a significant coefficient($R^2$=0.639) in four lakes for drinking water located in Nakdong River basin. The relationship between COD and TOC($R^2$=0.774) was higher with respect to the elevated concentration level when the data was added. Resulting in the oxidation(C) was $62{\pm}8%$ regardless of COD concentrations. It was difficult to find a significant difference by lakes. The result showed the similar organic property in study lakes. It was necessary to evaluate the level of organic matters in consideration of characteristics and utilization of lakes to use COD data wisely until TOC data be accumulated sufficiently.
