Abstract

The reliance on groundwater for various activities ranging from domestic, agricultural and industrial activities is ever on the increase in developing countries. The groundwater sources will, therefore, need to be evaluated constantly and periodically to ensure its portability and fitness for use. There is little documentation about the quality of water sources in Omu-Aran. This study therefore, is to assess water quality of borehole present in the area. In order to carry out the purported objective of this project, twenty-four samples withdrawn from boreholes of eight different locations across Omu-Aran were taken into consideration. Precautions and standard procedures were taken in its collection, storage and transportation in order to preserve the sanctity of the water samples. The procedures, materials and equipment required to carry out the test for each parameter such as electrical conductivity, dissolved oxygen, pH, nitrate, sulphate, zinc, nickel, E. coli, total coliform etc. were all in line with laid down standards and procedures. Results from the research revealed that the value of analyzed parameters were within the acceptable limits for potable water recommended by World Health Organization and Standard Organization of Nigeria except for iron, nickel, E. coli and pH. Iron, E. coli and nickel were much to above the limit while pH did not fall within the minimum and maximum limit allowed. Water quality index and spatial analysis using ArcGIS highlight the significance of these parameters. Borehole water in this region can be considered safe and of good quality but face huge risk of contamination by heavy metals and raises the question of suitability and effect of the drinking in the long run.
