Know what's in your air, water, and land.
Claymont sits at the intersection of I-95, the Delaware River, and decades of industrial history. We're documenting the pollution and health risks our community faces — and building the evidence to drive change.
Lenape Ecological Context
Before Claymont was a transportation corridor or an industrial zone, it was Lenape land. Naaman's Creek was a living watershed. The Delaware River was a source of life. That relationship continues — and it shapes how the Claymont Coalition for Environmental Justice (CC4EJ) understands environmental health: not just the absence of pollution, but the restoration of what was taken.
