Phase II ESA in Ontario
We provide Phase II Environmental Site Assessments (ESA) across Ontario to evaluate soil and groundwater conditions and support regulatory compliance, redevelopment and risk management.
What is a Phase II ESA?
A Phase II ESA is an intrusive investigation used to confirm the presence or absence of environmental contamination in soil and groundwater.
Phase II ESAs are typically recommended following a Phase I ESA where potential environmental concerns have been identified. The investigation involves drilling, sampling, and laboratory analysis to assess site conditions.
In Ontario, Phase II ESAs are often completed in support of regulatory requirements under Ontario Regulation 153/04, particularly when filing a Record of Site Condition (RSC).
When is a Phase II ESA Required?
A Phase II ESA may be required in Ontario for:
Properties with identified potential contamination (from a Phase I ESA)
Site redevelopment or change in land use
Regulatory compliance and Record of Site Condition (RSC) filings
Due diligence for property transactions
Completing a Phase II ESA helps quantify environmental risks and determine whether remediation is necessary.
