• What is the first step in a typical brownfield remediation process?
• Site redevelopment
• Site assessment
• Soil excavation
• Waste disposal

Rationale: A site assessment identifies contaminants and risks before any

remediation activities begin.

• Which type of assessment evaluates potential environmental

contamination from a property’s past uses?

• Phase III Environmental Site Assessment
• Phase I Environmental Site Assessment
• Phase II Environmental Site Assessment
• Baseline Ecological Assessment

Rationale: Phase I ESA involves historical research and site inspection to
