Groundwater pollution has been concerned in the agricultural area due to release of fertilizer, pesticide, and veterinary antibiotics (VAs). Especially, emerging contaminants such as VAs can cause adverse effect not only on ecosystem but also on human health. Main objective of this research was to examine groundwater near at the animal feeding operation for evaluating occurrence of VAs. Groundwater sample was collected from five different province and three sulfonamides antibiotics (sulfamethazine: SMZ, sulfathiazole: STZ, sulfamethoxazole: SMX) were measured. Extraction of antibiotics was conducted with solid phase extraction and HPLC/MS/MS was used for quantification. Recovery of three antibiotics was ranged 88-126% and R2 value of external calibration curve was 0.99 for all three compounds. Among 3 VAs, only SMZ was detected at the range of 26.6-40.0 ng L-1. Comparing SMZ concentration between control (no animal feeding operation within 2 km radius) and sampling points (animal feeding operation within 0.5 km radius), no difference was observed. This result might indicated that occurrence of VAs in the groundwater can be originated from compost spread in the agricultural field and released into groundwater after rainfall as a nonpoint source. However, more detailed analysis is required for better understanding of VAs occurrence in the groundwater.
