Protection #1: Remove the Source


Supersacks of PCB waste ready for transport
Removing the source means excavating contaminants, sorting these by waste type, and transporting to a disposal area in which contaminants are contained.
The 3 Protections = Defenses in Depth
- Protection #1: Remove the Source
- Protection #2: Stabilize or remove sediments
- Protection #3: Sampling for known and unexpected contaminants
