Water Quality Assesssment of Some Selected Well Waters of Yeregi in Katcha Local Government of Niger State

Abstract

Water quality assessment of some seleted well waters of Sabo Yeregi in Katcha Local Government Area of Niger state was carried out using standard analytical methods. Water is a valued natural resource for survival of all living things; the importance of assessing the quality of this valued resource cannot be overemphasized. In this study, the physical, chemical and microbial values were analyzed from six well water samples collected from Sabo Yeregi, Katcha Local Government Area of Niger State using standard methods. The pH ranges 6.30 ± 0.04 to 7.15 ± 0.07. Nitrite ranged from 0.03 ± 0.02 to 0.11± 0.01mg/L. Well 1(85.45 ± 0.64) has the highest total dissolved solids (TDS). Iron recorded 0.24 ± 0.02mg/L as the highest and 0.07 ± 0.00 mg/L as the lowest in well 5 and 6 respectively. The hardness for well 1, 2, 3, 4, 5 and 6 were 113.50 ± 0.71, 38.00 ±1.42, 63.00 ± 0.00, 27.50 ± 0.71, 31.50 ± 0.71 and38.00 ± 1.42mg/L respectively. The sulphate concentration is 64.68 ± 0.06, 89.22 ± 0.09, 92.74 ± 0.09 29.01 ± 0.09, 102.27 ± 0.41, and 77.25 ± 0.11mg/L for well 1, 2, 3, 4, 5 and 6 respectively. The highest temperature recorded was 29.06± 0.090C and the lowest was 27.92± 0.02 well 5 and 3 respectively. The turbidity was 4.42 ± 0.06, 0.50 ± 0.04, 0.36 ± 0.08, 2.06 ± 0.06, 2.37 ± 0.21 and 2.47 ± 0.05NTU for well 1, 2, 3, 4, 5, and 6. All the parameters were within the NSDWQ and WHO standard except pH in well 1, 2, 6, hardness, nitrate in (well 4) and manganese (in well 3). All the samples contain coliform with the exception of well 5 but there is no present of E.coli in any of the sample.
