Phase II Environmental Site Assessment (ESA) Services
Investigation of Environmental Conditions
​
When environmental concerns are identified during a Phase I ESA, the next step is often a Phase II Environmental Site Assessment (ESA). A Phase II ESA involves intrusive sampling and laboratory analysis to determine whether contaminants are present in soil, groundwater, or building materials.
​
Champion Environmental Consulting provides targeted, regulatory-compliant Phase II ESA services to help property owners, developers, lenders, and legal teams assess environmental risks, verify site conditions, and make informed decisions about remediation and site management
What Is Required?
A Phase II ESA is typically triggered when a Phase I ESA identifies Recognized Environmental Conditions (RECs)—evidence of potential contamination on or near the property. While a Phase I relies on historical research and visual inspections, a Phase II goes further by collecting physical samples and conducting laboratory analysis. Sampling activities must be performed following EPA, ASTM E1903-19, and applicable state standards. Proper Phase II investigations are designed with clear objectives, use appropriate sampling methods, and generate defensible data that can withstand regulatory, financial, and legal review. Failure to perform a Phase II ESA when contamination is suspected can expose stakeholders to liability for cleanup costs and future site restrictions.

What Is a Phase II ESA?
A Phase II ESA is an intrusive environmental investigation that uses scientific sampling methods to assess site conditions. It typically involves:
-
Soil sampling to detect surface or subsurface contamination
-
Groundwater sampling from monitoring wells or test borings
-
Indoor air and soil vapor testing where vapor intrusion may be a concern
-
Sampling of suspected asbestos-containing or lead-based materials, where applicable
The objective of a Phase II ESA is to determine if contamination is present, define the extent of contamination, and inform decisions about site management, remediation, or development feasibility.
Unlike a Phase I, which identifies the potential for issues, a Phase II provides concrete evidence regarding environmental impacts.
When Phase II ESAs Are Needed
​
A Phase II ESA is commonly performed when:
​
-
A Phase I ESA identifies Recognized Environmental Conditions (RECs)
-
Known spills, leaks, or hazardous material use occurred on or near the property
-
Underground storage tanks (USTs) are present or suspected
-
Regulatory agencies require confirmation sampling for permits or clean closures
-
Due diligence standards for financing or acquisition demand deeper investigation
Phase II ESAs are often required before redevelopment of industrial, commercial, or former agricultural properties to ensure there are no hidden risks.
Understanding the Risk
​
Undetected contamination can result in significant financial, legal, and operational consequences. These risks may include:
​
-
Mandatory environmental cleanup under state or federal law
-
Invalidation of property transactions or loan agreements
-
Civil lawsuits from adjacent property owners or affected parties
-
Long-term restrictions on land use and site redevelopment
By completing a Phase II ESA, property stakeholders gain the critical information needed to quantify risk, plan mitigation strategies, and protect against future liabilities.
