Key Uses of a Phase II Environmental Site Assessment (ESA) Report
A Phase II Environmental Site Assessment (ESA) report is one of the most critical tools in environmental due diligence. While a Phase I ESA identifies potential environmental concerns—known as Recognized Environmental Conditions (RECs)—a Phase II ESA goes further by providing scientific, defensible evidence about the presence, absence, and extent of contamination in the subsurface. This…

Conducting Interviews with Government Officials for a Phase I ESA
Conducting interviews with local government officials is a critical and often underutilized component of a Phase I Environmental Site Assessment (ESA). While database searches, historical records, and site reconnaissance provide essential information, government interviews can reveal authoritative, site-specific insights that are not available elsewhere. Standards such as ASTM E1527-21 and regulatory frameworks like Ontario Regulation…

The Use of Drones in a Phase I Environmental Site Assessment
The Phase I Environmental Site Assessment (ESA) has traditionally relied on records review, site reconnaissance, and interviews to identify potential environmental contamination risks. While these core components remain unchanged under ASTM E1527-21, technology is rapidly enhancing how Environmental Professionals (EPs) collect and document site information. One of the most impactful advancements in recent years is…
