Large amounts of white foam have appeared on beaches in the eastern coastal city of Chennai, India, stretching for several kilometers and emitting a pungent odor. Preliminary analysis indicates that recent heavy rains washed untreated sewage and industrial wastewater into the sea. Chemicals like detergents and phosphates mixed with seawater, forming foam through wave action. Despite local authorities collecting samples for testing and urging residents to avoid the contaminated area, children continue to play in the foam, risking skin and respiratory illnesses.
