ASSESMENT OF GROUNDWATER QUALITY FROM BOREHOLES AND HAND-DUG WELLS AROUND OBAJANA CEMENT FACTORY AND ITS ENVIRONS IN LOKOJA, KOGI STATE, NIGERIA

📄 Project Abstract

The groundwater (hand dug wells and boreholes) qualities of Obajana in Kogi State were determined. The study consisted of the determination of some heavy metals and physicochemical properties in drinking water samples. Ten (10) samples each of groundwater were collected from the four sampling sites The samples were analysed for the following parameters iron, copper, manganese, zinc, lead, nitrates, sulphate, phosphate, colour, dissolved solids, electrical conductivity, pH, dissolved oxygen( DO), biological oxygen demand (BOD), chemical oxygen demand (COD), temperature, turbidity, total hardness and total alkalinity using standard method. The data showed the variation of the investigated parameters in samples as follows: temperature 26-30oC, pH 5.53-7.89, electrical conductivity (EC) 6.210-339.670 S/cm, total hardness 50.00- 424.20 mg/l, alkalinity 1.10-145.67mg/l, turbidity 0.00-34 FTU, colour 5-15TCU, phosphate 0.02-0.760 mg/l, nitrate 10.24-48.20mg/l, sulphate 24.70-222.13mg/l, disso...
