Nobody knows what has happened near Buenos Aires yet! But baffled officials are investigating why the first section of the Parana River Delta turned blood red overnight in Tigre, Argentina Saturday morning. Residents have been asked to stay away from the waters until analyses have been run.
First biologists suggested that the red color was due to an algae bloom, but this hypothesis has been rejected after no such organisms were found in the water samples.
Now, officials suspect a clandestine dumping of industrial waste upstream in the area of Don Torcuato and recommended inhabitants to stay away from the water until authorities have the final results of the sampled water. This will take approximately 48 hours.
