Physico-Chemical Studies of Lonar Lake, Maharashtra, India

An attempt was made during present investigation to evaluate physicochemical qualities of water from Lonar Lake. For this purpose the water samples were analyzed for physico-chemical qualities, from 2012 to 2013 to find out seasonal variation. The results obtained revealed that, the water was alkaline (pH 10.5) characterized by high Alkalinity (5786 mg/liter), Sulphate (67 mg/liter), Magnesium (1043 mg/liter), Chloride (2816 mg/liter) and Dissolved Oxygen (0.03 mg/liter). The alkalinity increased in monsoon and postmonsoon seasons while it decreased in pre-monsoon season. Like wise the chloride and salinity increased in pre monsoon season while decreased in monsoon and post-monsoon season.
