How to Use This Calculator

Enter site size in acres from the property survey or remedial investigation boundary.
Rate contaminant complexity (1=simple petroleum, 5=mixed chlorinated solvents/metals).
Select the remediation technology (pump-and-treat, soil excavation, in-situ, MNA, or thermal).
Rate regulatory burden (1=low, 5=high state oversight) and select your state program.
Review phase durations (investigation, RI/FS, design, construction, operations) and total project timeline.
