Evaluation of groundwater quality of selected boreholes in Ohaozara and Ivo Council Areas of Ebonyi State, Nigeria

Abstract

Groundwater quality in study areas was evaluated by measuring the physicochemical parameters including selected ions in water samples collected from 12 boreholes in Akaeze, Okposi and Uburu towns of Ebonyi State, Nigeria in April, 2013 and analysed using standard methods. Results obtained showed that, except for As5 content, all other parameters investigated fall within WHO standards for potable water. Regression analysis showed that conductivity, SO42- and As5+ levels are important variables in predicting the TDS values of the samples while NO3, Cl-, PO43- and TDS are important in predicting the As5+ content of the water samples. One-way ANOVA at P < 0.05 showed Fcal (1.862) > Ftab (0.619), implying a significant difference between the parameters for all locations.
