A Phase 1 Environmental Site Assessment (ESA) evaluates potential environmental contamination risks associated with a property. It is commonly required for real estate transactions, financing, redevelopment, and municipal approvals.
Phase 1 ESAs are typically conducted following CSA Z768-01 Phase I Environmental Site Assessment Standard. The assessment identifies potential contamination risks based on historical land use, site observations, and regulatory records.
At Bluray Environmental, Phase 1 ESAs help property owners, investors, and developers understand environmental risks before purchasing or developing land.

What Does a Phase 1 ESA Include?
A Phase 1 ESA is non-intrusive, meaning no soil or groundwater sampling is conducted. The assessment typically includes:
Historical Records Review - aerial photos, land use records, and environmental databases
Site Inspection – identifying signs of potential contamination such as fuel storage, stained soil, or waste handling areas
Interviews – discussions with owners, tenants, or site personnel
Regulatory Database Review – checking government records for spills or contaminated site listings

Final Report – identifying Area of Potential Environmental Concern (APECs) and recommendations
If concerns are identified, a Phase 2 Environmental Site Assessment may be recommended.

Why Phase 1 ESA Is Important
A Phase 1 ESA helps:
✔ Identify environmental risks
✔ Support real estate transactions and financing
✔ Meet lender and municipal requirements
✔ Reduce environmental liability
