Abstract
Lonar Lake, also known as the Lonar crater, is a monument to the National Geo-Heritage Monument, a salt, soda reservoir, located in the Lonar region of Buldana in Maharashtra. An attempt has been made to test the physicochemical properties of water in Lonar Lake. A total of 4 water samples were analyzed in 2008 for pre-term physiological properties of Lonar lake water and revealed that the water was alkaline (pH 10.5) and characterized by high salts (9060mg/L), chloride (4125.69 mg/L), Salinity (7599.81 mg/L), Alkalinity (3503 mg/L), Total hardness (494 mg / L), Calcium hardness (142.8 mg/L), Magnesium hardness (351.2 mg/L), Sulphate (21.75 mg)./L), Phosphate (0.42 mg/L) and Nitrate (4.2 mg/L), and Dissolve Oxygen (4.7 mg/L). As Lonar Lake is different from the rest of the world in terms of quality of water and salt water. So this earth's heritage should be preserved for its alkalinity and salt.
