An Owner’s Perspective on Proactive Remediation on Complex Sites

Clients and site owners may have a reputation of doing the bare minimum to meet remedial objectives, but, at many sites, a case can be made to proactively reduce contaminant mass in order to reduce future risk and costs while stabilizing cash reserves. Increasing attention on vapor intrusion and extremely mobile emerging contaminants makes proactive remediation more compelling now than ever before. The differences in how companies view lifecycle reserves and cash flow, and how this affects present-day remedial decisions, are discussed. Several case studies are presented that use a business case to justify proactive remediation.
