The drinking water in Paradise, California, where 85 people died last year in the nation’s worst wildfire in a century, is contaminated with the cancer-causing chemical benzene, officials said. Officials said they believe the contamination happened after the November firestorm created a toxic combination of gases in burning homes that got sucked into the water pipes as residents and firefighters drew water heavily, the Sacramento Bee newspaper reported Thursday. Officials say that may explain why benzene, which has been linked to anemia and leukemia, has been found in tests at various spots rather than from one source in Paradise, which was largely destroyed.
