- Property Transactions & Financing: ESAs are essential during real estate transactions to ensure no hidden environmental risks affect the property’s value.
- Pre-Redevelopment or Construction: Urban properties, especially those with industrial or commercial history, need an ESA before redevelopment.
- Older Properties: Properties with a history of hazardous material use, such as asbestos, petroleum, or industrial waste, require thorough assessment to prevent future risks.

What Our Clients Say About Us
Certified Comprehensive ESA Process
Compliance & Environmental Risk Management
At GAC Environmental, we conduct thorough and compliant assessments following the three phases of ESA to provide clarity and risk management for your property.
Our Environmental Site Assessment Process:
We help you navigate real estate transactions and redevelopment projects by identifying and mitigating environmental risks.
- Phase I ESA – Preliminary Assessment:
Our team conducts a detailed site inspection, reviews historical property records, and interviews past owners to identify potential contamination risks. This phase helps detect any environmental liabilities before moving forward. - Phase II ESA – Confirmatory Testing:
If Phase I reveals contamination risks, we collect soil, water, and air samples for laboratory analysis to confirm the presence of hazardous substances. Phase II provides concrete data on contamination levels to guide remediation efforts.
Phase III ESA – Remediation & Cleanup:
For properties with confirmed contamination, Phase III involves designing and implementing a remediation plan, including soil excavation or water treatment, to ensure the property is safe for use. This phase ensures your property meets environmental standards and is ready for development or sale.
