More residents of Paulsboro, N.J. have been ordered to leave their homes because of air contamination from a train derailment last week that leaked a hazardous gas. So far, 200 homes have been evacuated and schools closed until next week because of air quality concerns.
Meanwhile, in northwest Louisiana, it will be the end of the week before all six million pounds of improperly stored explosive powder at the Explo Systems facility at Camp Minden are safely secured.
The powder was found spilling out of boxes crammed into buildings, after an October explosion prompted an inspection of the facility and led to the evacuation of the nearby town of Doyline.
