Assessment of Borehole Water Quality in Nigeria Maritime University, Kurutie – Takeoff Campus and Environment

Abstract

The assessment of borehole water quality in NMU: Kurutie – Takeoff Campus and environment has been done. The water quality assessment, which is a compelling constituent of the grantee of the health and wellbeing of both students and staff of the university, has been appraised. The physicochemical analysis of the samples A and B are pH of 8.1: 7.0; DO of 3.5mg/L:2.9mg/L; BOD5 of 2.2mg/L:1.8mg/L; conductivity of 416 µs/cm: 340µs/cm; TDS of 207mg/L: 170mg/L; nitrate of 0.3mg/L:23mg/L; turbidity of 2. 0NTU:12NTU and hardness of 202.2mg/L: 121mg/L respectively. The results show some disagreements between the different sites. Site A recorded the highest pH of about 8.1confirming the total hardness of water at the site. And the same readings for the BOD5, which show a lower value of it depicting the cleanliness of organic matter. While the electrical conductivity – an estimate of total dissolved solids-depicts higher readings in Site B, which is lesser than the TDS 500mg/L set for drinkable water. It is recommended that quality assessment of the boreholes in order to improve the quality of water supply should be carried out to correct the disparities between sites.
