The team of trained experts at Sage Environmental provide high quality technical expertise, advice, and support to our clients as part of Stage 1 / Phase I Investigations.
Stage 1 Preliminary Site Investigation (PSI)
Stage 1 Preliminary Site Investigation (PSI): Also referred to as a Phase 1 Environmental Site Assessment (ESA) is a method used to assist in determining potential environmental liabilities due to contamination on a site or property. This process involves a detailed review of land uses and history including a site visit, record searches, personal interviews and the evaluation of related information and reporting. This information is compiled and used to determine the potential of impact on a site due to contamination. Our reporting will provide conclusions and recommendations whether further investigations if warranted, such as a Stage 2 PSI / Phase II ESA.
