Key Takeaway Points
• Remediation of contaminated land is a process with
many links (steps) in the Value Chain
• You can’t skip a step without losing time & money
• Technology is just one piece of the process but not the
most expensive piece
• An accurate Site Conceptual Model is the critical
leverage point to ensure proper cost-effective
remediation design and success
• High-resolution information is critical to minimizing
the uncertainty in the Site Conceptual Model
