Environmental Remediation Planning & Corrective Action Support
A Phase III Environmental Site Assessment is typically performed after contamination has been confirmed through a Phase II ESA or other environmental sampling. This phase focuses on determining the appropriate next steps for addressing confirmed soil, groundwater, soil vapor, or site-related contamination.
Our Phase III ESA services are designed for property owners, buyers, sellers, lenders, developers, attorneys, property managers, investors, and real estate professionals who need clear documentation, remedial planning support, corrective action guidance, and environmental cleanup coordination.
What is a Phase 3 ESA?
A Phase III Environmental Site Assessment (Phase III ESA), is the environmental assessment and remediation planning stage that may follow a Phase II ESA when contamination has been identified. The purpose is to further define the extent of contamination, evaluate appropriate corrective action options, and support the development of a remedial action plan.
Depending on the property and contaminant type, a Phase III ESA may include additional sampling, contamination delineation, remedial planning, excavation oversight, groundwater treatment review, soil management coordination, regulatory communication, or long-term monitoring. In simple terms, Phase I identifies potential concerns, Phase II tests whether contamination is present, and Phase III focuses on addressing confirmed contamination.
Why Do I need A Phase 3 ESA?
For commercial buyers, lenders, and shareholders, a Phase III ESA:
- Helps address confirmed contamination identified during a Phase II ESA.
- Supports remediation planning, corrective action, and cleanup decision-making.
- Helps evaluate soil, groundwater, vapor, or site-related contamination impacts.
- Supports regulatory coordination, contractor planning, and long-term risk management.

Remedial Planning & Corrective Action
The purpose of a Phase III ESA is to move from confirmed contamination to a practical plan for addressing the condition. This may include reviewing Phase II data, identifying impacted areas, estimating the extent of contamination, evaluating potential remedial approaches, and supporting the development of a corrective action or remedial action plan.
Common Phase III ESA work may include:
- Additional soil, groundwater, or soil vapor delineation
- Remedial action planning
- Soil excavation planning or oversight
- Groundwater treatment evaluation
- Regulatory documentation or closure support
Standalone Remediation Planning or Corrective Action Support
Not every project requires a full Phase III Environmental Site Assessment. Some clients only need targeted remedial planning, additional delineation, contractor coordination, confirmation sampling, environmental documentation, or review of an existing Phase II report.
Full Spectrum Environmental can provide standalone support when a limited scope is more appropriate than a full ESA process. This may include review of petroleum, solvent, VOC, pesticide, herbicide, lead, arsenic, PFAS, groundwater, soil vapor, or site-specific contamination concerns.
Frequently Asked Questions
A Phase III Environmental Site Assessment is the assessment, planning, and corrective action stage that may follow a Phase II ESA when contamination has been confirmed. It may include additional delineation, remedial planning, cleanup coordination, monitoring, or regulatory documentation.
A Phase III ESA is commonly needed when soil, groundwater, soil vapor, or other environmental sampling confirms contamination above applicable screening levels or regulatory criteria. It may also be requested by lenders, attorneys, buyers, developers, property owners, or regulators.
A Phase III ESA may include review of prior data, additional sampling, contamination delineation, remedial action planning, excavation oversight, groundwater monitoring, vapor mitigation coordination, regulatory communication, and written reporting.
A Phase III ESA is often associated with remediation, but the exact scope depends on the project. It may include planning, coordination, oversight, confirmation sampling, documentation, or support for cleanup activities performed by qualified contractors.
Common contaminants may include petroleum hydrocarbons, VOCs, dry-cleaning solvents, heavy metals, pesticides, herbicides, PFAS, and other site-specific contaminants identified during prior sampling.
