According to officials, additional tests did not confirm the bacteria’s presence and there is no health risk, according to the story.
“We re-sampled, and all of our regular samples Monday, and all of our regular samples Tuesday, all of our additional samples Tuesday came back negative except for just that one for Reservoir Number One,” said David Shaff, water bureau administrator.
This is the first such incident since E. coli was detected at the reservoir last Thanksgiving, the article stated.
