골프장에서 발생하는 비점오염원 유출특성

초록

Activities on golf courses are believed to contribute to the degradation of water quality in receiving waters due to the excessive use of farm chemicals including fertilizers and pesticides. The objective of this study was to collect basic data that could explain the characteristics of non-point source (NPS) pollution discharged from a golf course. Twenty seven water quality monitoring was conducted at a golf course during the rainy season of 2008 and 2009. The results indicated that the ranges of the Event Mean Concentration (EMC) at the golf course were BOD_5 1.8~11.3 (ave. 5.6) mg/L, COD_(Mn) 19.2~51.4 (ave. 39.6) mg/L, TOC 11.0~31.0 (ave. 16.8) mg/L, TN 1.545~16.098 (ave. 5.623) mg/L, TP 0.230~4.528 (ave. 1.525) mg/L, and SS 2.2~57.3 (ave. 10.1) mg/L. The unit loads of the golf course estimated were BOD_5 3.35 kg/km^2/day, SS 6.43 kg/km^2/day, COD_(Mn) 30.00 kg/km^2/day, TN 4.04 kg/km^2/day, TP 1.14 kg/km^2/day, and TOC 12.16 kg/km^2/day. Golf courses are currently classified as a grass field in which the unit loads are different from golf courses. Therefore, it was recommended that golf courses need to be separated from the grass field when the surveys and modelings for Total Maximum Daily Load (TMDL) development and the evaluation of TMDL implementation were performed.
