To investigate the influence of livestock farm's wastewater on the near stream, the water quality of 3 different streams are analysed after seasons. In summer, the minimum T-N in the upper stream was 0.005 ppm and the maximum T-N in the down stream was 5.005 ppm. The phosphate was detected only in down stream of S2 point and was 0.5 ppm. COD was varied from 8 ppm in upper stream to 20 ppm in down stream. In fall, the T-N and the phosphate had shown similar results as that of in summer, however COD was varied from 3 ppm in upper stream to 6 ppm in down stream. In winter, the minimum T-N in the upper stream was 0.053 ppm and the maximum T-N in the down stream was 0.51 ppm. The phosphate was detected only in down stream of S2 point and was 0.5 ppm. COD was varied from 3 ppm in upper stream to 6 ppm in down stream. To be becoming fall and winter, the water quality of streams showed better than that of summer, and the wastewater from the livestock farms had little influence on the near streams.
