Bunkerhill Superfund Site

Remediation efforts at the Bunker Hill Superfund Site restore contaminated land, transforming it into thriving ecosystem.

Once one of the largest contaminated sites in the U.S., the Bunker Hill Superfund Site is undergoing a major environmental transformation. Decades of industrial activity left behind heavy metal contamination, impacting soil, water, and wildlife. Through a comprehensive remediation effort, this site is being restored into a safer, healthier ecosystem.

The Challenge: Decades of Industrial Pollution

Bunker Hill’s history of mining and smelting operations resulted in widespread lead, arsenic, and heavy metal contamination. The scale of pollution required a long-term, strategic approach to environmental recovery.

A Focus on Sustainable Remediation

Efforts at the site include:

Soil and water treatment to remove hazardous contaminants

Revegetation initiatives to restore natural landscapes

Ecosystem monitoring to ensure long-term recovery

By applying advanced remediation techniques, the project aims to stabilize the environment while minimizing disruption to local communities.

A Future of Renewal

Once a site of industrial degradation, Bunker Hill is now a model for environmental restoration. Through careful remediation, the area is being transformed into a safe and thriving ecosystem, ensuring a healthier future for both people and wildlife.
