As a cross sectional study the biological and chemical oxygen demand (BOD and COD), Dissolved Oxygen (DO), Nutrients(PO4, NO2-2-N, NO3--N, NH4+-N), Electrical conductivity(EC), total Hardness(TH) and total Alkalinity(Talk), pH, total Coliforms(TC) and total Fecal Coliforms(FC), water temperature and heavy metals using standard metiiods in eight sampling stations along the river were measured within one year and three times. Results were analyzed using SPSS software and descriptive statistics. Results have been shown that pH has not been many changes and were at 8.1-8.5 range, maximum and minimum of total Hardness, there was at D and G stations, respectively and amount of SO4 in all stations was in drinking standard level. Mean water temperature was at 8.5-13°C range and EC maximum and DO a minimum(3.1 mg/1) there were in B and C stations, respectively. Changing range of PO4 and NO3-N were (0.22-0.94mg/l) and (0.04-1.2mg/l), respectively and concentration of Barium and Iron heavy metals were more to other surveyed heavy metals. The results of water quality Aydughmush review showed that certain pollution along the river, no water quality substantially be affected. However, in addition to artificial sources, river water quality through erosion and deposition can also be negatively affected. Livestock waste is one of die factors affecting the river pollution (as non-point sources). © 2011 RASAYAN. All rights reserved.
