Environmental Sampling for Property Due Diligence
A Phase II Environmental Site Assessment is used to investigate specific environmental concerns identified during a Phase I ESA, transaction screen, regulatory review, or site-specific due diligence process. Unlike a Phase I ESA, which is primarily based on records review and site observations, a Phase II ESA includes physical sampling to evaluate whether contamination is present.
What is a Phase 2 ESA?
A Phase II Environmental Site Assessment, often called a Phase II ESA, is a sampling-based environmental investigation used to evaluate whether hazardous substances, petroleum products, or other contaminants may be present at a property. The assessment is typically performed when a Phase I ESA identifies Recognized Environmental Conditions, commonly referred to as RECs, or when a specific environmental concern requires further investigation.
The purpose of a Phase II ESA is to collect environmental samples, submit them for certified laboratory analysis, and compare the results to applicable screening levels or regulatory criteria. Depending on the property and concern, sampling may include soil, groundwater, soil vapor, surface water, sediment, or building-related materials.
Why Do I need A Phase 1 ESA?
For commercial buyers, lenders, developers, and property stakeholders, a Phase II ESA:
- Helps confirm whether suspected contamination is present.
- Provides laboratory data for soil, groundwater, soil vapor, or other environmental media.
- Supports lender, attorney, buyer, seller, or redevelopment decision-making.
- Helps evaluate concerns identified during a Phase I ESA or regulatory review.
- Provides documentation that may support risk management, negotiation, or next-step planning.

Our team supports commercial real estate buyers, lenders, developers, attorneys, property managers, and property professionals who need environmental sampling and laboratory analysis before closing, refinancing, redevelopment, or site-use decisions.
Environmental Sampling & Laboratory Analysis
The purpose of a Phase II ESA is to move from suspected concern to laboratory-supported data. Sampling locations are selected based on the recognized environmental conditions, historical property use, regulatory records, site observations, and the suspected source of contamination
Common Phase II ESA sampling may include:
- Soil sampling
- Groundwater sampling
- Surface water or sediment sampling
- Building material or source-area sampling when applicable
- TVOC Screening
Standalone Soil or Groundwater Testing
Not every project requires a full Phase II Environmental Site Assessment. Some clients only need targeted soil, groundwater, water, vapor, or material testing for a specific concern, property condition, or due diligence question.
Full Spectrum Environmental can provide standalone environmental sampling when a limited scope is more appropriate than a full ESA. This may include testing for petroleum, solvents, VOCs, pesticides, herbicides, lead, arsenic, PFAS, or other site-specific contaminants.
Frequently Asked Questions
A Phase II ESA is commonly needed when a Phase I ESA identifies a Recognized Environmental Condition or when a specific property history suggests possible contamination. It may also be requested by lenders, attorneys, buyers, developers, or regulators.
A Phase II ESA may include a sampling plan, site access coordination, soil borings, groundwater sampling, soil vapor sampling, laboratory analysis, data review, and a written report summarizing findings and recommendations.
If contamination is found above applicable screening levels or regulatory criteria, additional investigation, delineation, regulatory review, or remediation planning may be recommended. The next step depends on the contaminant, concentration, location, and intended property use.
A Phase I ESA reviews records, historical use, regulatory information, and site observations to identify potential environmental concerns. A Phase II ESA collects samples and uses laboratory analysis to evaluate whether those concerns are actually present.
Yes. Full Spectrum Environmental can provide standalone soil, groundwater, soil vapor, water, or material testing when a full Phase II ESA is not required and the concern is limited to a specific contaminant or area.
What is a Phase III ESA?
If a Phase II ESA confirms contamination above applicable criteria, a Phase III Environmental Site Assessment or remedial planning process may be recommended. Phase III work may involve additional delineation, cleanup planning, remediation support, regulatory coordination, excavation oversight, groundwater treatment review, or documentation of corrective action.
A Phase III ESA is typically focused on addressing confirmed contamination, while a Phase II ESA is focused on investigating whether contamination is present and whether additional action may be needed.
