What is a multiphase investigation?
Multiphase investigations are focused on determining the appropriate corrective action following a finding of need resulting from a Phase I environmental assessment. Depending on summary reports, the impact, facility location, and applicable regulations, a risk assessment may be appropriate to determine the actual risk. Once the risk has been determined, a feasibility study may determine the appropriate corrective action. Corrective actions can consist of no further action, a simple removal action, or full-blown corrective action under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) or the Resource Conservation and Recovery Act (RCRA).
