| Abstract |
| The purpose of this research is to quantify the pollutant concentrations from driveway sites. For this aim, the magnitude and nature of the emission of the runoff pollutants were investigated. A statistical summary for the concentration characteristics of driveway runoff was resulted from various analysis techniques. The 95 % confidence intervals of washed-off pollutant concentration were ranged 82.4-141.4 mgL-1 for TSS, 53.27-87.64 mgL-1 for Turbidity, 18.95-38.65 mgL-1 for BOD, 34.04-59.23 mgL-1 for COD, 16.39-27.39 mgL-1 for DOC, 4.27-5.58 mgL-1 for TN and 0.25-0.34 mgL-1 for TP, showing high values based on the surface or lake quality standards in Korea. The concentrations of water quality constituents in urban stormwater were often expressed in terms of probability statistics such as mean, standard deviation and selected quintiles. This study looks at the concentration changes and characteristics during storm occurrence in driveway site. The new concept explaining the relationship among the emission effects of runoff pollutants were suggested using statistical techniques. Based on the results of this and the related investigations, actions were taken to manage the driveway runoff. |
