Recently the water quality management policy gives priority to management the point source. Non-point pollution source is difficult to comprehend because those don't have certain outflow point and emission. There are many development and research about BMPs for manage the Non-point pollution source. Various methods of removal efficiency are presented for assessment of Best Management Practices (BMPs). In this study, retention time have effect on removal efficiency based on monitoring results of Grassed Swale is studied. Also, Compare a difference according to various methods of Grassed Swale removal efficiency. The result of removal efficiency analysis depending on retention time of Grassed Swale, removal efficiency is higher as retention time increases. To obtain a stable removal efficiency of Grassed Swale, retention time of Grassed Swale should be secure.
