Bengaluru is often described as India’s Silicon Valley. However, tech headlines have been recently consumed by reports of the white froth. Decades of excessive construction and industrialization have contaminated Bellandur Lake, Bengaluru’s largest body of water. The cause of the smelly foam? Increased phosphate levels in the water, which worsens during periods of heavy downpour. Due to high levels of hydrocarbons and oils in the water, the lake caught fire in May. Residents say the smell is almost unbearable. Instead of searching for a long-term solution, local authorities have only taken temporary measures such as installing water sprinklers to dilute the foam.
