Toxic Chemical Discharge in Delaware River Raises Concerns Over Water Safety in Philadelphia.

Eleven industrial plants have legally released toxic chemicals into the Delaware River over the last five years, according to reports filed to federal officials. Two facilities, the PBF Energy refinery in Paulsboro and the Monroe Energy refinery in Trainer, accounted for 4.4 million pounds of toxic chemicals emptied into the river since 2017. The river is a major thruway for ships carrying petroleum products and other chemicals that can spill into the Delaware. The records do not provide a full picture, as the reports rely on voluntary compliance when a company releases toxins.
