Comparative analysis of sixteen (16) borehole water supply sources collected from Emohua and Ngor Okpala Local Government Areas (hereafter referred to as LGAs) were carried out in December 2017 to March 2018. Physicochemical parameters were analyzed using analytical techniques and instruments to study the level of pollutant concentration as index of mine exploitation. Coordinates were used to differentiate the boreholes by way of some physicochemical parameters, while multiply analyses of variance was applied. The results obtained showed mean values of pH (4.66 ±0.05), conductivity (82.100 ±0.05), alkalinity (0.056 ±0.05), chloride (1.146 ±0.05), total dissolved solids (45.140 ±0.05), total organic matter (0.024 ±0.05), sulphate (0.030 ±0.05) and iron (0.357 ±0.05). The realized pH values indicate that the boreholes are acidic. Moreover, the Fe levels in some boreholes were above the permissible limit of the water standard. From the results of the ANOVA, the null hypothesis (H0) revealed significant differences in pH, Cl¯, TDS, conductivity, whereas other factors such as alkalinity, SO42¯, total organic matter and Fe were not significant in both LGAs. The coordinate results also showed that chloride increases as sulphate decreases in both LGAs. Furthermore, total organic matter increases with increase in alkalinity and Fe increases with increase in TDS in the two LGAs as well. This concludes that there is pollution in the two study areas.
