The Environmental Protection Agency hosted a public hearing on plans to remove radioactive waste in Queens.
The site in question is the former Wolff Alport Chemical Company along Irving and Cooper Avenues in Ridgewood.
Workers at the building, now a federal Superfund area, dumped hazardous waste starting in the 1920s and into the late 40s.
The EPA wants to relocate nearby businesses, demolish the buildings, and remove all the contaminated soil that sits there.
Residents at the meeting say they want to know how safe this plan is and how it will affect the community.
"We're concerned because we have children," said one neighbor. "We live literally a block from where everything is."
"We don't know what's going to happen," said another. "We don't know if these chemicals are going to have cancer. We don't know nothing. So hopefully they can answer something."
The plan is expected to cost about $40 million.
The public comment period will continue for the next couple of weeks.
