Water quality of Young San river was examined for 3 months from April 12, 1989. to Jun 12, 1989. For checking the water quality 4 sampling position were selected.
The results we obtained are as follows.
1. The average for Young San river was 6.6¡7.4 of pH, 3.6¡8.7mg/§¤of Dissolved dxygen (DO), 18.67¡33.47mg/§¤of chemical oxygen demand (COD), 47.66¡250mg/§¤ of suspended solid (SS), 37.83¡114.66mg/§¤ of N-hexane abstraction maters, 5.16¡6.63mg/§¤ of BOD.
2. The monthly average for Young San river was 6.5¡7.5 pH,3.5¡10.4mg/§¤ of DO. 15.07¡48.90mg/§¤ COD, 6.2¡10.2 mg/§¤ of BOC, 2¡250mg/§¤ of SS. 2¡124mg/§¤ of N-hexane abstraction mater, in April, 6.2¡7.5 of pH, 3.5¡8.2mg/§¤ of DO, 2.4¡5.7mg/§¤ BOD, 18.21¡32mg/§¤ of COD, 16¡123mg/§¤ of SS, 9.5¡95mg/§¤ of N-hexane abstraction matter, in May 6.9¡7.5 of pH, 3.8¡7.50mg/§¤ of pH, 3.8¡7.50mg/§¤ of DO, 4.0¡5.8mg/§¤ of BOD, 18.23¡of COD, 123¡163mg/§¤ of SS, 102¡125mg/§¤ of N-hexane abstraction matter in Jun.
3. The sampling positions averag for Young San San river was 6.9¡7.5 of pH, 7.5¡10.4mg/§¤ of DO, 15.07¡22.8mg/§¤ of COD, 3.5¡6.2mg/§¤ of BOD, 2¡125mg/§¤ of ss, 2¡102mg/§¤ of N-hexane abstraction matter in posiction 1.7.3¡7.5 of pH, 6.0¡7.5mg/§¤ of DO, 46.25¡52.05mg/§¤ of COD, 2.4¡8.5mg/§¤ of BOD, 58¡123mg/§¤ of SS, 62¡120mg/§¤ of N-hexane abstration matter in position 2. 6.2¡7.3 of pH, of pH, 4.23¡6.7mg/§¤ of DO, 4.9¡7,9mg/§¤ of BOD, 18.23¡36.75mg/§¤ of COD, 89¡152mg/§¤ of SS, 75¡123mg/§¤ of N-hexane abstraction matter, in position 3, 6.5¡7.2 of pH, 4.0¡10.2mg/§¤ of BOD, 3.5¡3.82mg/§¤ of DO, 23.6¡52.32mg/§¤ of COD, 123¡250mg/§¤ of SS, 95¡125mg/§¤ of N-hexane abstraction matter in position 4.
