Abstract

Water quality of the Samsami and Dinaran rivers of Chaharmahal and Bakhtiari province were assessed in year 1393. For each river, 7 stations were determined. Water sampling has been done monthly (May to October) and samples, under standard situation, were sent to laboratory for assessing: Nitrite, Ammonium, Soluble Phosphate, BOD5, COD, TSS, TDS, Cu, Zn, Hg, Cl-, Organophosphate toxins, pH, Malachite green and EC. Soluble phosphate was higher than standard in studied rivers (p<0.05). There were increasing trend for all recorded parameters from first to last station. Except for the low number of stations, BOD5 and COD were equal or lower (p<0.0001) than its standards. There were some malachite green in studied rivers especially at their last station (p<0.002). Other parameters were lower than standard for two rivers (p<0.05). Generally, water quality of these two rivers was absolute, but, for development new trout culture farms, Nitrite, Phosphate and Malachite green must be controlled.
