In many parts of Nigeria, groundwater is one of the most essential sources of water. Pollution brought on by petroleum products (a complete mixture of hydrocarbons) has been acknowledged as a severe environmental issue. This research is aimed at examining the impact of automobile repair activities on well water quality in Aule, Ondo state, Nigeria. Physio-chemical parameters such as temperature, turbidity, pH, electrical conductivity, total dissolved solids, alkalinity, acidity, total hardness, chloride, nitrate, sulphate, phosphate, total suspended solids, magnesium, calcium and bacteriological parameters from 5 wells in different automobile workshops and a control well in Aule were analyzed in this research. The results were compared with the WHO standards. The analysis revealed that the mean values of NO3, SO4, Mg, Ca, and pH were within the WHO permissible limit, while the mean value of the other water parameters exceeded the WHO permissible limit. Also, NO3 negatively correlated pH, and positively with Ca (r=0.873, p<0.05). PO4 correlated positively with Ca (r=0.903, p<0.05). TDS correlated negatively with Temp, and pH and positively with TSS (r=0.879, p<0.05). pH correlated negatively with EC, pH, and TVBC. This study also revealed that poor waste disposal practices by automobile repairers, inadequate regulatory frameworks, and a lack of awareness among community members on the dangers of groundwater pollution are contributing factors to the problem.
