The Chemical prediction of groundwater quality in parts of Owerri in Imo State was carried out. The chemical parameters of groundwater samples from Nekede, Ihiagwa, Eziobodo, Obinze and Avu were subjected to chemical analysis using standard laboratory techniques . In the study, an equation was formulated that will predict the chemical concentrations of contaminants of the groundwater aquifer at any given distance in Owerri in Imo State. A total of three replicates of fifteen different borehole water samples were collected based on distances from closest potential sources of contamination. All parameters were detected up to 60m from pollution source and most of them increased in concentration during the periods, pointing to infiltrations from storm water. The results for concentration of Mn, Zn, Mg, and Hardness decreased as distance increases while further increase in distance may decrease or increase the values of Cu. Results also showed that most of the boreholes were polluted and not suitable for human consumption without adequate treatment. This study accentuates the need to set standards for the siting of wells from septic tanks, abolishment of unhealthy waste disposal practices and introduction of modern techniques are recommended.
