Phase I and II Environmental Site Assessment / Stage 1 & 2 Preliminary Site Investigation
A Phase I/Stage 1 is generally required as part of a commercial or industrial real estate transaction in to identifying potential environmental liabilities and to support financing. Phase I / Stage 1 involves reviewing information on historical and present land use to determine the presence of areas of potential environmental concern (APECs), potential contaminants of concern (PCOCs), hazardous materials, waste and other substances that may negatively affect future use of the property. A Phase II / Stage 2 is recommended when environmental concerns are identified on the property, and involve the collection of soil, vapour and/or groundwater samples to verify or refute potential contamination identified in the Phase I / Stage 1. We scope our preliminary investigations to satisfy client needs and objectives (e.g., financing, regulatory compliance), and endeavor to take an approach that reflects the risk tolerance of each client.
Detailed Site Investigation
If subsurface contamination is identified during the Phase II / Stage 2, a detailed site investigation will be completed to delineate the full extent of contamination (both vertically and horizontally), and to evaluate the severity of contamination. Detailed site investigations generally provide the data and information needed to satisfy regulatory requirements, and serve as the framework for site remediation.
