摘要：Only small amount of freshwater is available to us. Industrial, domestic and agricultural wastes are drainedin surface water so the pollution of water increasing day by day. The present study area comes under semiarid climate zone. The physiography of study area is rugged and somewhere plain in central part. The areais covered by quaternary alluvial and underlain by Deccan basalt of cretaceous to eocene age. The area hasmajor irrigation networks and water is used continuously for various purposes. The chemical quality ofsurface water is of great importance in determining the suitability of water for specific use. Surface watersamples were collected from different irrigation projects for analysis and the parameters include pH, alkalinity,hardness, COD, BOD, TSS, chlorides, phosphate, nitrate, SAR, ESP, etc. It is observed that pH is significantlydecreased with the increasing pollution load. Pollution load increases organic matter which is turn decreasesDO and increases HCO 3 . From the evaluation of carbonate hazards, it is clear that the surface water is safefrom bicarbonate hazards and the water quality is suitable for Irrigation and domestic purposes.
