What is a Phase I Environmental Site Assessment (ESA)?
A Phase 1 Environmental Site Assessment (Phase I ESA) evaluates a property for potential environmental contamination and liability risk prior to purchase, financing, or development. Phase I ESAs are commonly required for commercial real estate transactions, including property acquisitions, bank financing or refinancing, due diligence, and development projects. Identifying environmental risks early helps protect buyers, lenders, and investors from potential liability and unexpected costs.
Our Phase I ESA services include:
- Historical records review
- Environmental database search
- Site inspection (reconnaissance)
- Interviews and records review
- Identification of Recognized Environmental Conditions (RECs)
All assessments are conducted in accordance with ASTM E1527-21 standards and meet All Appropriate Inquiry (AAI) requirements for liability protection.
Phase II Environmental Site Assessments
If a Phase I Environmental Site Assessment (Phase I ESA) identifies potential environmental concerns, a Phase II Environmental Site Assessment (Phase II ESA) may be required to confirm the presence and extent of contamination. A Phase II ESA is a targeted investigation designed to evaluate environmental conditions and quantify potential impacts at a property. The results help guide real estate decisions, regulatory compliance, and, if necessary, the next steps for remediation. By clearly defining site conditions, a Phase II ESA reduces uncertainty and allows projects to move forward with confidence.
Phase II ESA services include:
- Soil and groundwater sampling
- Monitoring well installation
- Vapor intrusion testing
- Laboratory analysis
Because Olympus combines environmental consulting with in-house drilling and field services, we can mobilize quickly and complete Phase II investigations without delays between multiple contractors.

RECEPTIVE, ADAPTABLE, AND PROACTIVE
“We worked with Olympus to demolish, dispose, and backfill two buildings containing hazardous materials. Olympus’ crew was receptive to our requests, adapted to changing site conditions, suggested ways to increase efficiency, and didn’t sway from their proposed cost. Together we changed the site from dilapidated hazardous buildings to a clean construction-ready property.”
