In this study, olive oil samples of different irrigation system of different regions in Palestine were studied. The density, refractive index, acidity and viscosity of the samples were measured. The acidity of olive oil samples from different location and different irrigation system was measured. The overall results indicate that acidity increase for samples their trees were irrigated by waste water and classified to Lampante oil, and most of the olive oil samples are classified to be ordinary virgin oil. The viscosity of olive oil samples of 2014 crop from different regions was studied. The experimental results of viscosity showed that the viscosity increased for samples were irrigated by waste water. The concentration of some metals in olive oil samples irrigated by waste water was found to be highly concentrated compared with literature values of metals.
