Golf course community has always been concerned about water quality regarding to pesticide and fertilizer managements. This study conducted to investigate sorption and leaching behavior of common pesticides used for golf course in granular activated carbon I (GAC 1), granular activated carbon II(GAC II), and charcoal. We used batch study to investigate the influence of concentrations of Smithion and Folicur and particle sizes of GAC I, GAC II, and charcoal on sorption. Also, column study was used to investigate the leaching effect of Smithion in GAC I and charcoal. We found that sorption of Smithion and Folicur were higher in less $45{\mu}m$ of particle size for GAC I, GAC II, and charcoal compared to $1.7{\sim}2.0mm$ size, and the sorption of Smithion and Folicur in less $45{\mu}m$ of particle size ranged from 90 to 99%. In the column study, there was no difference in leaching effect between GAC I and charcoal. Overall, we found that charcoal might offer a cost effective adsorbent as a pesticides in leachate.
