Abstract:
The present investigation was conducted to evaluate the ground water quality of Manjra River basin from Latur district. Total 100 water samples were collected and analyzed for pH, EC TDS, TH, cations (Na+, K+, Ca+2 and Mg+2), anions (SO4-2, Cl-, HCO3- and CO3- 2), SAR, RSC and RSBC. The pH and electrical conductivity of ground water samples were 7.01 to 8.35 and 0.35 to 1.8 dSm-1, respectively. Total dissolved solids and total hardness of water were ranged from 224 to 1152 mg L-1 and 145 to 450 mg L-1, respectively. The relative abundance of major ions for most of the water samples were Na+ > Mg+2 > Ca+2 > K+ for cations and SO4-2 > Cl- > HCO3- > CO3-2 for anions. Sodium adsorption ratio (SAR), residual sodium carbonate (RSC) and residual sodium bicarbonate (RSBC) varied from 2.6 to 6.36 (mmole/l1/2), nil to 3.5 me L-1 and 1.5 to 6.4 me L-1, respectively. According to AICRP classification, it was found that 93% water samples were good quality and 7% were marginal alkali in nature. On the basis of correlation studies it can be concluded that pH, EC, TDS, TH, Na+, K+, Ca+2, Mg+2, SO4-2, Cl-, HCO3-, CO3-2, SAR, RSC and RSBC showed good positive correlation with each other.
