A large dark stain was spotted off Barra da Tijuca beach in Rio de Janeiro this week, prompting concern from locals and environmental experts over its cause and potential impact.
A massive dark stain appeared in the ocean off Rio de Janeiro’s Barra da Tijuca beach on Wednesday, May 14, raising environmental concerns among residents, beachgoers, and researchers. The discolored water was clearly visible in aerial footage captured by Reuters drones, showing a stark contrast between the murky brown patch and the surrounding blue sea.
According to Brazilian outlet Globo, the dark waters originated from the Barra and Jacarepaguá lagoon complex. The state environment institute, Inea, explained that an ebb tide - dropping from 1.1 meters (3.6 feet) to just 0.2 meters (0.65 feet) - carried organic material from the lagoons into the sea. The resulting interaction between warmer seawater and cooler lagoon water caused a change in color.
Preliminary assessments from Inea suggest that the phenomenon does not negatively affect seawater quality or pose a health risk to swimmers. The institute has collected water samples and plans to release detailed analysis results by Friday, May 16.
Despite the early reassurances, experts are pointing to deeper structural issues. Biologist Mario Moscatelli attributed the stain to long-standing urban development problems and inadequate sanitation in the region. “The sewage flows down the rivers, into the lagoon, and from the lagoon into the sea,” he said in a statement to Reuters.
While authorities continue their investigation, the incident has reignited calls for better urban planning and sewage treatment infrastructure to protect Rio’s waterways and coastal ecosystems.
