The main objective of this study is to diagnose the quality of groundwater and the impact of the F'kirina gas turbine power plant on it.10 samples were taken from boreholes and wells in the aquifer exploited in the region and used for human consumption. The results obtained showed that the water is polluted, particularly in terms of conductivity, total hardness and the concentration of minor elements. The study of the pollution parameters showed that there was an excess in the concentration of nitrates as well as sodium and sulphate. This may probably be due to the proximity of agricultural land as well as the gas turbine power plant in the case of some boreholes. To this end, ongoing assessment of water quality is deemed necessary and treatment to reduce water quality deterioration and eliminate health problems may be required.
