Assessments of some physical and chemical properties were conducted  for two Libyan water bodies (Ain Al- Ghazala and Umm-Hufayn). Of each ecosystem, ten water samples were taken from ten points for analysis. The results showed that the electric conductivity in Ain Al-Ghazala Bay waters is higher than that in the waters of Umm-Hufayn Lake. In the two areas, the hydrogen ion concentration pH recorded the highest value with a value of 8.3, with mean values of chloride (Cl) exceeding the internationally recorded limits. Furthermore, nitrites (NO₂₎, nitrate (NO₃₎, sulphate (SO₄₎, phosphate (PO₄₎, silicates (SiO₂₎, carbonate (CO₃₎, calcium (Ca), magnesium (Mg), sodium (Na), and potassium (K) were all greater in Ain Al-Ghazala Bay waters than in Umm-Hufayn Lake waters. In conclusion, more attention should be directed to the preservation of such natural resources.
