Snowfall in Bengaluru? Mysterious White Foam Covers City Streets After Rainfall
Bengaluru residents were in for a strange sight after a recent spell of rainfall—streets in several areas appeared to be covered in what looked like snow or white foam. The unusual phenomenon left many wondering if it was an unexpected snowfall in the city, but the reality was quite different.
What Really Happened?
The white foam seen on Bengaluru’s streets was actually the result of chemical reactions and pollutants mixing with rainwater. Bengaluru, known for its urban lakes and industrial zones, has been dealing with the issue of toxic froth formation, particularly in water bodies like Bellandur and Varthur lakes. The recent rainfall likely washed pollutants, detergents, and industrial waste into drainage systems, leading to foam accumulation on roads.
Why Does This Foam Form?
-
Pollution & Chemical Waste: Many industries and households release untreated waste, including detergents, phosphates, and chemicals, into lakes and drains.
-
Heavy Rainfall: When it rains, these pollutants mix with water and get agitated, forming thick white foam.
-
Wind & Drain Overflow: Strong winds and overflowing drains can cause this foam to spill onto roads, creating an illusion of ‘snowfall.’
Is It Dangerous?
Yes, the foam is not harmless. It often contains toxic chemicals and can cause skin irritation, respiratory problems, and environmental hazards. In the past, residents near Bellandur Lake have complained about the froth catching fire due to its high chemical content.
Steps Taken by Authorities
The Karnataka Pollution Control Board (KSPCB) and local authorities have been working to control pollution in Bengaluru’s lakes. Measures such as sewage treatment plants (STPs), penalties for polluting industries, and public awareness campaigns have been introduced, but the problem persists due to rapid urbanization and inadequate waste management.
Conclusion
While it may have looked like an unusual snowfall in Bengaluru, the reality is a stark reminder of urban pollution. The foam-covered streets highlight the urgent need for better waste treatment, pollution control, and sustainable urban planning to prevent such incidents in the future.
