Abstract
Water quality assessment was carried out in University of Benin and environs in order to evaluate the impact of surface anthropogenic activities on the quality of ground water. Ten (10) water samples obtained from borehole ground water were analyzed for their physio-chemical and microbial parameters using standard techniques. The result of the analysis shows pH (5.32 - 5.88), Calcium (1.62 – 6.69), Magnesium (0.40 – 1.63), Sodium (4.3 – 17.83), Total dissolved solids (18.36 – 75.78), Potassium (1.80 – 13.24), Lead (0 – 0 – 0.9), Iron (0.11 – 0.45), Nickel (0.25 – 1.04), E coli (0 – 13). The result of the analysis shows a majority of the ions to be below the standard limits. The pH of the water is below standard limits and is said to be slightly acidic. The low concentration of Calcium, Magnesium, Potassium, sodium, suggests the water to be soft. But spikes in the concentration of the heavy metal content and the presence of feacal coliform suggest the water to be receiving elements of contamination via natural source or from surface anthropogenic activities.
