Phase I and Phase II Environmental Site Assessments
A Phase I ESA is a desktop based assessment that identifies potential contamination through historical research, site inspection, and interviews. It takes into consideration past and current land uses to determine if contamination is likely present without physical sampling.
Phase II Environmental Site Assessment addresses the concerns brought up in Phase I and involves thorough investigation into the level of contamination through collecting soil and groundwater samples. This investigation confirms whether contamination exists and outlines the extent.
