The Philadelphia region still has 70 Superfund sites, with three in Delaware County, that have not been cleaned up and may be under consideration for redevelopment, writes Frank Kummer for the Philadelphia Inquirer.

Thousands of Delco residents live within a mile of these sites: Havertown PCP, the Lower Darby Creek Area in Darby Township, and Matro Container Corporation in Trainer.

Environmental Protection Agency officials are using the Metal Bank Superfund Site in Philadelphia that was recently purchased by Revolution Recovery as an example of their potential. The agency has started rolling back the environmental rules set during the Obama Administration.

However, it has emphasized that it will focus on the core mission of the remediation and redevelopment of the sites. EPA officials also said they intended to make a small push to get the sites redeveloped while still ensuring they are safe.

Environmentalists like David Masur, executive director of PennEnvironment, are worried about the actual outcome of this push. Currently, the Trump Administration is attempting to reduce EPA funding.

“It’s a very high-risk game, given the dangerous nature of some of these sites,” he said.
