How could the cleanup of the Franklin Slag Pile affect Philadelphia?
Reduced contamination in the Delaware River may lower environmental risks for Philadelphia. The cleanup of the Franklin Slag Pile, a Superfund site in Port Richmond, New Jersey, is designed to prevent hazardous materials from entering the Delaware River. Historically, slag from the site migrated off-site and coated storm drains that empty directly into the river. By treating the slag with a chemical solution and containing it in sealable bags before disposal, the EPA and its contractors are reducing the source of contaminants. This reduction in pollution entering the Delaware River could mitigate environmental and public health risks for Philadelphia, which relies on the river.

How it reaches Philadelphia
-
The U.S. Environmental Protection Agency is monitoring contaminants entering the Delaware River near residents in New Jersey. Separately, the EPA began planning the removal of the Franklin Slag Pile, a Superfund site located in Port Richmond, Philadelphia. This site contains approximately 68,000 cubic yards of slag, a byproduct of metal smelting, and cleanup began in July after years of planning and design.
The full event1independent outlet -
Since the slag historically coated storm drains that empty directly into the Delaware River, reducing the contaminant load in the river lessens the overall environmental risk associated with the river for major nearby cities like Philadelphia.

Why it matters
The Franklin Slag Pile represents a long-standing environmental hazard, containing about 68,000 cubic yards of stony byproduct from metal smelting. The cleanup is crucial because the site's proximity to the Delaware River means that historical and ongoing contamination poses a risk to the river's health and the surrounding communities, including Philadelphia.
This effort is part of the broader Superfund process, which requires companies responsible for contamination to fund the cleanup. The EPA is working alongside the Army Corps of Engineers and environmental remediation companies to ensure the site is eventually ready for development, addressing a regional pollution issue that affects multiple states along the Delaware River.
