Water quality in Rio's Guanabara Bay for the sailing events during the 2016 Olympics will vary with the weather, Brazilian biologist Mario Moscatelli told EFE Monday. "On rainy days and at low tide, the IOC president's comments will collide with reality," the scientist said. Moscatelli, however, pointed out that the testing regime cannot guarantee the quality of the water. Moscatelli, who has spent more than two decades working in the Rio de Janeiro area, said that a combination of rain, low tide and a north wind will be bad for water quality in the bay. High tide and winds blowing from the south, conversely, will push out the garbage and freshen the bay with cleaner Atlantic waters, he said.
