Analytical parameters were NH₄+-N, NO₂？-N, NO₃--N, PO₄3？-P as nutrient index and COD as organic index by water test reagents in conjunction with spectrophotometric method. The result has been shown total inorganic nitrogen,phosphorus and COD were ranged 0.72~6.01 ppm, 0.01~0.49 ppm, 1.73~19.99 ppm respe ctively. Contamination degree of water quality was increased from Chunho Bridge to downstream.
