Bellandur lake foam threatens residents: Pollution & heavy rains fuel the crisis

Bengaluru's Bellandur Lake, already infamous for its pollution, is facing a new crisis as a massive formation of toxic foam has emerged, causing alarm among residents in the vicinity.

The cause behind the foam formation:

The alarming foam formation in Bellandur Lake can be attributed to the severe pollution that plagues the water body. Over the years, untreated sewage, industrial waste, and other contaminants have entered the lake, making it one of the most polluted water bodies in Bengaluru. When the rainwater mixes with the already polluted lake, it causes the water to foam up, particularly in areas where the water flow increases.

The pollutants, including detergents and chemicals, react with the water, creating large, thick foam that rises above the water's surface. Due to the ongoing rains, the water levels in the lake have risen, causing more foam to form and spread over the surrounding areas. This foam, driven by gusty winds, has made its way into nearby residential areas, including Bellandur, Kariyamma Agrahara, Yamaluru, Kempapura, Chalaghatta, Nagasandra, Ibbalur, Devarabisanhalli, and Kadubeesanahalli, raising fears among residents about potential health risks.

The environmental impact of foam:

Experts have warned that the foam, caused by the presence of toxic chemicals and detergents in the lake, can pose serious health risks if inhaled or if it comes into contact with skin. The toxic nature of the foam and the polluted water contribute to the growing environmental concerns in the area. Scientists also point out that the untreated wastewater entering the lake takes 10-15 days to leave, during which time harmful gases and organic matter settle at the bottom of the lake, further exacerbating the pollution.
