Well-water samples were collected from the vicinity of Balogun–biiro dump site located in Okebaale Osogbo, Osun state, Nigeria. The polycyclic aromatic hydrocarbons were determined qualitatively and quantitatively using GC-FID. The concentration of polycyclic aromatic hydrocarbons in the water samples ranged from 0.01235 µg/kg to 0.05365 µg/kg with mean concentration ranging from 0.00094 µg/kg to 0.00335 µg/kg respectively. The highest concentration of ∑16 ð‘ƒð´ð»ð‘ was recorded in S6 and it was observed that there is decline in polycyclic aromatic hydrocarbons concentrations from point of water pollution. There was a significant concentration of both the lower and higher rings polycyclic aromatic hydrocarbons in the samples. These distributions as well as various polycyclic aromatic hydrocarbons diagnostic indices calculated showed that the sources of polycyclic aromatic hydrocarbons in the samples were both petrogenic and pyrogenic. The mean concentrations of polycyclic aromatic hydrocarbons recorded in the water samples showed a little bit enhanced values than the recommended tolerable limits, which indicated some level of pollution in the water samples
