The Role of Historical Source Review in Phase I Environmental Site Assessments
A Phase I Environmental Site Assessment (ESA) is fundamentally an investigation into the past. While the site visit and interviews provide a snapshot of current conditions, it is the historical source review that reveals how a property has evolved over time—and whether past uses may have introduced environmental risks. Historical source review is one of…
