Evaluation of Groundwater Quality of Selected Boreholes in Ohaozara and Ivo Council Areas of Ebonyi State, Nigeria
Groundwater Quality Evaluation in Nigeria
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, SO4 2- and As5+ levels are important variables in predicting
the TDS values of the samples while NO3-, Cl-, PO4 3- 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.
