The water quality of the Bandi river is under the stress of severe pollution due to discharge of effluents from more than 800 textile dyeing and printing industries located at Pali city. The river carries exclusively industrial effluents throughout the year except in monsoon period. The study revealed that the chemical parameters -COD(993 mg/L), suspended solids (800 mg/L),chloride (1702 mg/L), sulphate (943 mg/L), sodium (2163 mg/L) and Cr+6 (0.15 mg/L) have exceeded the maximum discharge limits laid down by Bureau of Indian Standards. A decrease in concentration of various pollutants downstream Pali during monsoon season was observed due to dilution of industrial waste waters by the flow of fresh water upstream of Pali city.
