Essential to both life and wellness is water. Water is a basic necessity for living a healthy and respectable life, hence every person has the right to get it. It is necessary for all additional human rights to be realized. Lake water has already been sought after as a source of water by many developing and poor nations in order to offer healthy drinking water. In the center of Mumbai's suburbs, Powai Lake is flanked by Powai Garden and Vihar Lake. The investigation of the levels of heavy metal pollution in the water has been conducted around the Powai and Vihar Lakes. The sampling has been done along selected seven sites of both the lakes. Water samples have been regularly drawn for 2 years for three seasons i.e., summer, monsoon (Pre-monsoon and Post-monsoon) and winter. Physical, chemical, and heavy metal characteristics of water samples have been examined. In both lakes, the collected water samples were analyzed in 2021–2022, looking for certain heavy metals (As, Al, Cd, Cr, Co, Cu, Fe, Hg, Mn, Ni, Pb, and Zn). Selected heavy metals have been detected using an AAS-ICP-AES (atomic absorption spectrometer, inductive coupled plasma, and emission spectrometer). The AAS-ICP-AES method used in this study to analyses samples of lake water for heavy metals produced excellent findings for both lakes. Even while the investigation found certain heavy metals, their concentrations were not excessive enough to qualify as chemical contamination. This could be as a result of the river's generation power of domestic sewage (including animal waste from cow sheds) from its source at Powai to where it meets Mahim Creek. This area's domestic sewage volume is far greater than the amount of industrial effluent discharged, which could provide dilution. The contrast above clearly shows that environmental activity is hardly evident due to the enormous volume of home sewage. The study found that the effluent and untreated sewage from the neighborhood have a negative impact on Powai Lake
