The laboratories and other buildings that once housed a chemical manufacturer here in New Jersey's most populous city have been demolished. More than 10,000 leaky drums and other containers once illegally stored here have long been removed. Its owner was convicted three decades ago. Yet the groundwater beneath the 4.4-acre expanse once occupied by White Chemical Corp. in Newark remains contaminated, given a lack of federal funding. But three decades after federal officials declared it one of America's most toxic spots, it's about to get a jolt. This plot in Newark is among more than four dozen toxic waste sites to get cleanup funding from the newly-enacted infrastructure law, the Environmental Protection Agency announced Friday, totaling $1 billion. "This work is just the beginning," EPA Administrator Michael Regan said. President Biden signed legislation reviving a polluter's tax that will inject a new stream of cash into the nation's troubled Superfund program. The renewed excise fees, which disappeared more than 25 years ago, are expected to raise $14.5 billion in revenue over the next decade and could accelerate cleanups of many sites that are increasingly threatened by climate change. The Superfund list includes more than 1,300 abandoned mines, radioactive landfills, shuttered military labs, closed factories and other contaminated areas across nearly all 50 states.
