The present study was aimed to access heavy metals contamination of groundwater in Ila Orangun community, Osun State, Nigeria. Six (6) functional hands dug wells and four (4) boreholes within three streets area were randomly selected in the study. Water samples were collected during dry season (December, 2015 and February, 2016) and rainy season (June and September, 2016). The result of physical parameters revealed that there was significant difference (p < 0.05) between the value obtained for temperature during dry and rainy season whereas pH value showed no significant difference (p > 0.05) between dry and rainy season, almost all the heavy metal determined were found above the permissible limit of WHO 2008 except As and Zn that were within the permissible limits. The study concluded that metals determined in this study suggested that pollution of the well water and boreholes in the area as being attributed to anthropogenic activities.
