In the aftermath of dead fishes being seen in Mumbai's Banganga Tank, a chemical analysis of the tank's water undertaken by the Brihanmumbai Municipal Corporation (BMC) suggests oxygen deficiency, reports stated.
According to an account by the Times of India, officials suggest that the number of fish had outgrown the capacity of the tank causing many to die owing to insufficient oxygen.
Based on the narratives, the civic body's report highlights the tank's watercolour of light green which signifies toxic components.
A senior civic official was quoted in the report elaborating on how the water report found oil, and grease, amongst other solid components. Additionally, the water's turbidity is high which portrays oxygen deficiency. This phenomenon is believed to have caused the fish's death.
The official added that they collected water samples from the inlet and tank. Herein they found that the level of oil, grease, suspended oil components and ammonia is greater in the water tank as opposed to the water from the inlets.
The official elucidated that while the colour of the tank water has changed to light green, the inlet's colour has not changed.
Last month, droves of fish were found floating dead in the Malabar Hills area at the Banganga pond. Locals have elaborated on how they have been throwing these dead fishes out of the pond since the occurrence.
