An unexplained odor of rotten eggs is causing distress to residents of the San Francisco Bay Area. From Science Alert:
"PG&E received 45 calls about a gas-like odour in several different neighborhoods, according to company spokesman J.D. Guidi," reports Ted Goldberg at KQED.
"The Fire Department got more than 30 calls, according to that agency's spokesman, Jonathan Baxter. Callers described the odour as 'rotten eggs or sulphur,' … The calls initially came from the downtown area and then moved toward the Marina, Sunset, and Richmond neighbourhoods."
The weird thing is that even with so many different companies, the Fire Department, and government agencies such as the Coast Guard launching investigations into the smell, no one has been able to pin down what exactly caused the sudden flare up.
