The deadly wildfires in Paradise last year has polluted the drinking water with a cancer-causing chemical. Paradise Irrigation District officials say they have detected elevated levels of benzene in the tap water. The toxic chemical can lead to leukemia. Residents who are still living in Paradise are being warned not to consume or use the water in any way. Cleaning the water system will take about 300-million-dollars and around two years to remove benzene from the water supply.
