Phase I & Phase II Environmental Site Assessments Across Long Island
Before buying, selling, or developing commercial or industrial property, it’s critical to understand the site’s environmental condition. Enviroscience Consultants provides comprehensive Phase I and Phase II Environmental Site Assessments (ESAs) across Long Island and Queens area helping clients uncover potential liabilities, meet regulatory requirements, and make informed real estate decisions.
Our Asbestos Testing & Inspection Services
-
Phase I Environmental Site Assessments (ESA)
A Phase I ESA is the first step in identifying potential environmental risks associated with a property. This investigation is typically required by lenders and real estate investors during due diligence, refinancing, or redevelopment projects.
-
Phase II Environmental Site Assessments (ESA)
When a Phase I identifies potential contamination or Recognized Environmental Conditions (RECs), a Phase II ESA provides the scientific testing and data to confirm or rule out those concerns.
-
Environmental Transaction Screens (ASTM E1528-06)
A streamlined option for lower-risk properties, offering faster, cost-effective screening while still providing essential environmental insight.
-
Vapor Intrusion Assessments (ASTM E2600-08)
We assess the potential for vapors from subsurface contamination to migrate into indoor air and provide mitigation strategies if VOC or gas levels exceed safe limits.
When Do You Need a Phase I or Phase II ESA?
Understanding when to schedule an ESA can prevent costly surprises later in your project.
You should order an Environmental Site Assessment when:
- Purchasing or refinancing commercial or industrial real estate
- Redeveloping a property with prior industrial or automotive use
- Applying for financing or environmental insurance
- Seeking liability protection under the “Innocent Landowner” defense
- Identifying potential contamination from nearby properties
Enviroscience helps clients navigate each stage from initial due diligence to remediation oversight if required.

Frequently Asked Questions About Asbestos Testing
How long does a Phase I ESA take?
Typically 2–3 weeks depending on site size, historical complexity, and records availability.
Do all properties require a Phase II ESA?
No. A Phase II is only recommended when a Phase I identifies recognized environmental conditions (RECs) that warrant further testing.
Are ESAs required by law?
Not always, but lenders and regulatory agencies often require them before financing, permitting, or redevelopment approval.
