Assessment of Water Quality of Powai Lake, Mumbai, India

In Mumbai, increasing population always raises the demand for water supply. The main sources of water to Mumbai are five impounded lakes, Vehar, Powai, Tulsi, Tansa, Vaitarna and Upper Vaitarna. Powai Lake is in the heart of the city, located near the Vehar Lake. It was constructed by the British in 1891 to supply water to Mumbai city. Powai Lake water supply is mainly to Aarey colony and nearby industries since its water is unfit for human consumption. In spite of cleaning and maintaining Powai Lake, quality of water is deteriorating due industries and human activities around Powai Lake. By proper cleaning and regular physicochemical analysis potable water may get from Powai Lake to fulfil the requirement of increasing demand. To study the pollution level of Powai Lake some physic-chemical parameters were investigated. This study revealed high pollution level of Powai Lake.
