Physico.hemical parameters o. surface water co.lected fro. six different po.nts (P1 to.P6) o. River So.o.o.were analysed during j.nuary (Dry Seaso.) and August (Rainy Seaso.), 2014 to.determine its water quality using standard metho.s. The highest temperature o. 25.6°C was reco.ded by P1 in dry seaso. while P5 reco.ded the highest value o. 29.2°C in rainy seaso.. All the water samples were alkaline in dry seaso. with the highest pH value o. 8.50 in P5 and the least value o. 8.02 in P6 whereas in rainy seaso., P1, P2 and P3 were slightly acidic while P5 and P6 were slightly neutral and P4 alkaline. The highest values o. 510 μS/cm and 850.3 mg/l were reco.ded fro. P4 fo. electrical co.ductance and hardness respectively in the rainy seaso. whereas in dry seaso., P5 and P4 had the highest values o. 321 μS/cm and 282.8 mg/l respectively. The highest Do.and Bo. levels in dry seaso. were 1.7 mg/l and 0.7 mg/l respectively in P1 and the least values were 0.7 mg/l and 0.2 mg/l respectively in P5. But in the rainy seaso., P6 reco.ded the highest Do.value o. 0.1 mg/l while P2 and P5 reco.ded the least value o. 0.07 mg/l. Fo. Bo., P5 had the highest value (2.13 mg/l) while P3 had the least value (0.20 mg/l). Fo. Co., the highest value (230 mg/l) was fo.nd in P4 and P6 and the least value (30 mg/l) was fo.nd in P1 in dry seaso. while in the rainy seaso., P2 had the highest Co. value (1008 mg/l) and P4 had the least value o. 32 mg/l. TDS and TSS values generally were higher in the rainy seaso. than in the dry seaso. due to.higher amo.nt o. flo.ting particles in the rainy seaso.. While P1 and P6 reco.ded the highest values (800 mg/l and 700 mg/l respectively) in the rainy seaso., P4 reco.ded the least value o. 100 mg/l in bo.h seaso.s. The highest Chlo.ide level was fo.nd in P4 in the dry (100 mg/l) and rainy (180 mg/l) seaso.s with the least level in P2 (35 mg/l) in dry seaso. and in P1 and P2 with the least level o. 60 mg/l in the rainy seaso.. The highest co.centratio.
