Abstract


The study in this research is to evaluate Obite and Ogbogu groundwater quality. Studentized range test were used to appraise the relationship between water parameters assessed of Obite and Ogbogu community and the results obtained indicates that there is significant difference between Obite and Ogbogu community water quality parameters investigated as the percentage point of studentized range at 5% level with 70 degrees of freedom, when compared with the calculated modified studentized range, which indicates that there is significant difference between Obite groundwater parameters and Ogbogu groundwater parameters assessed pointing that water quality parameters of a particular region varies due to geological formation, depth of well and hydraulic conductivity and others functional factors within aquifer zone. The water quality index of Obite and Ogbogu groundwater falls into the class of good water quality as values of 48 and 37 were determined respectively.

Keywords: Studentized range test, water quality index, mean, variance, groundwater, Obite, Ogbogu
