Abstract
This study assessed water quality in Karanga River, Kilimanjaro Region, Tanzania. It employed quantitative and qualitative purposive effluents water sampling from two selected points along Karanga River stations, one from point source and to the consumer level at Shirimatunda Ward for comparisons. The water samples were analyzed for Turbidity, Temperature, TDS and EC, Color, pH, DO and TSS and Total Coliforms. The results of Turbidity, Temperature, TDS, TSS, pH and DO collect in February and April were within TBS, & WHO permissible standards with no restrictions to use. Color (81.88 ± 2.59 TCUs) & Total Coliforms 712.5 CFU/100 mL collected in February-dry and April-wet seasons were above the TBS (2016) range from (1-50 TCUs, and 500 CFU/100 mL) permissible limits indicated more polluted in wet season due to runoff. It is recommended to treat the wastewater influent from domestic and industrial sources before discharging it into Karanga River.
