Abstract
This study assessed the level of polycyclic Aromatic Hydrocarbons (PAHs) in underground water (well and
boreholes) use as sources of drinking water in Girei, Adamawa State, Nigeria. Water samples from the
study areas were collected from 21 sampling points and analyzed using GC/MS. From the results obtained,
acenaphthylene has the highest concentration of 0.091μg/l in well water (WW 10. In borehole water
samples, acenaphthylene has the highest concentration of 1.1 in BHW2 and lowest concentration value
0.0081μg/l was recorded in BHW6 and in most of the boreholes. Biphenylene and Fluorene were not
detected in both well water and borehole water in the study areas. Generally, the values of PAHs recorded
are higher in borehole than in well water. Some of the PAHs values recorded, especially for borehole water
were above the tolerable limits of 1μg/l set by FEPA and EU and as a result, effort needs to be intensified
toward combating further pollution of drinking water in the study area.
