ABSTRACT Since the water quality has been recognized as a big issue in drinking water sources, the Ministry of Environment, Korea, are designing the TMDL program for major large rivers. In order to settle the TMDL program successfully, nonpoint pollutants causing from various landuses should be controlled. Especially paved areas such as parking lots and bridges are stormwater intensive landuses because of high imperviousness and high pollutant mass emissions from vehicular activity. Vehicle emissions from these paved areas include different pollutants such as heavy metals, oil and grease and particulates. Therefore, this research has been conducted to understand the magnitude and nature of the stormwater emissions with the goal of quantifying stormwater pollutant concentrations and mass emission rates from a parking lot and a bridge. Two monitoring sites in Kongju city were equipped with an automatic rainfall gauge and an automatic flow meter for measuring rainfall, water quality and runoff flow. This manuscript will summarize the concentration changes during storm duration and EMCs in a parking lot and a bridge. The first flush criteria will be also suggested using dynamic EMCs. It is a new concept explaining the relationship of the EMC and first flush effect.
