A Study On The Physico-Chemical Parameters And The Microbial Flora Of A Eutrophic Lake –Pallavaram Lake (Periyar Lake), Zamin Pallavaram, Chennai, Tamilnadu, India.

Abstract

Water may be a critical resource within the lives of individuals who both enjoy its use and who are harmed by its misuse and unpredictability (flooding, droughts, salinity, acidity, and degraded quality). Consequently, consumption of polluted water puts lives and livelihoods in danger because water has no substitute. There are some ways during which water intended for human consumption can get polluted. These include wastes from industries like mining and construction, food processing, radioactive materials from power generating industries, domestic and agricultural wastes and by various microbiological agents. The pollution scenario in India is equally critical posing great threat to human health, aquatic life, vegetation and ecological balance. during this paper, the consequences of polluted lake water and analyzed by various analytical tests that this lake water was highly contaminated by the open defecation activities and mixture of domestic wastes which has been confirmed by the presence of microbial agents like Escherichia coli and Staphylococcus aureus hence itΓÇÖs not suitable for human consumption has been proved.
