San Francisco will have to spend $14 billion filtering nutrients from human POOP to stop growth of huge algae bloom blamed for killing thousands of fish in city's famed bay
San Francisco Bay is covered in a giant algae bloom that first appeared in July
Officials say that treated human waste from the eight million residents is what is fueling the bloom
There are 37 plants in the region, with the smallest dumping 85 million gallons of treated human waste into the Bay that contains at least 5.5 tons of nitrogen
Officials say they could limit the amount of nutrients dumped into the Bay
This, however, would cost $14 billion to update all of the region's plants
California officials say it will cost $14 billion to upgrade aging wastewater facilities that are dumping nutrients from treated human sewage into San Francisco Bay, which are feeding a giant algae bloom that has lingered for more than two months and killed tens of thousands of fish.
The algae bloom, which appeared in late July, has grown to an immense size because of the tons of nutrients from urine and feces of the eight million Bay Area residents that is released into the waters daily - one plant alone dumps 85 million gallons a day that contains 5.5 tons of nitrogen.
Scientists say the bloom was triggered by climate change, but its size, amount of organisms and how long it has lasted is due human waste.
