Abstract

Introduction Groundwater which is the last assumed resort for safe and potable water is now at great risk to contamination due to anthropogenic activities that aids industrialization. In Nigeria, the endless dependent on petroleum products for automobiles, fuel, power generation and the nation’s economy has geometrically proliferated the siting of filling stations all over the country where products sold are stored and channeled through underground storage tanks and pipe networks into the dispenser which lies above the water level. Hence, this study compared the ground water quality in Ogbomoso north and south metropolis. Methods A purposive descriptive study was conducted where a total number of 35 stations above the age of 15 were involved in the study. A total number of 50 samples was collected across those stations and its environment and this samples were subjected into physiochemical and heavy metals using standard techniques. Results The result of the physical parameter show that the alkalinity and hardness are the only parameters that are above standard level. All other average means of the physical parameter across the two geographical location are within the WHO recommended standard. Majority of the heavy metals of the two local government fall within the recommended standard limit givens by WHO expect for iron with the mean of 0.863 for Ogbomosho north and 0.461 for Ogbomosho south which is above WHO standard level of 0.3. The result shows that both geographical point and element are statistically significant. Conclusion Based on the data obtained, it can be concluded that water from the various different locations have different level of quality. Most of the samples were safe for human consumption and other domestic, industrial and agricultural proposes. They were soft, and with other quality parameters well within the permissible range
