Phase I Environmental Site Assessments
Protect your investment from hidden liabilities. We provide rapid, ASTM E1527-compliant assessments for real estate transactions across Texas.
Don't Inherit a Liability.
Verify Before You Buy.
A Phase I ESA is more than a checklist—it is your primary defense against purchasing contaminated land. Under federal law (CERCLA), property owners can be held strictly, jointly, and severally liable for multimillion-dollar cleanup costs even if they did not cause the pollution.
Envirogyn’s assessment strictly satisfies the federal "All Appropriate Inquiries" (AAI) requirement under 40 CFR Part 312, establishing your Innocent Landowner Defense, Bona Fide Prospective Purchaser (BFPP) status, and securing your commercial financing with institutional certainty.
Under ASTM E1527-21, assessments identify Recognized Environmental Conditions (RECs), Controlled RECs (CRECs), and Historical RECs (HRECs). Completing an ESA within 180 days prior to property acquisition is required to preserve CERCLA safe-harbor protections.
Standard & Speed: Engineered for Transactions
Commercial acquisitions move on aggressive contingency timelines. We provide defense-grade environmental due diligence calibrated for institutional velocity.
Standard: ASTM E1527-21 Compliant
Full compliance with the latest ASTM E1527-21 consensus standard and EPA 40 CFR Part 312 All Appropriate Inquiries rules. Exhaustive evaluation of adjoining parcels, historical aerials back to 1940, and emerging contaminants including PFAS/PFOA compounds.
Speed: Rapid Turnaround Available
Standard delivery within 2 to 3 weeks, with expedited 5-to-10 business day turnaround available for critical option periods and earnest money deadlines. Same-day site deployment across Galveston, Harris, Brazoria, and Houston metro counties.
Who Needs a Phase I Environmental Site Assessment?
Whether acquiring retail centers, industrial parks, or multi-family assets, a Phase I ESA protects capital and ensures regulatory compliance.
Commercial Buyers
Avoid inheriting millions in cleanup costs. Know the property's historical environmental footprint before you execute purchase contracts or waive contingencies.
Lenders & Banks
Essential for commercial underwriting (SBA 504/7(a), Fannie Mae, Freddie Mac, institutional lenders) to ensure asset collateral remains unencumbered by environmental liabilities.
Developers
Identify Recognized Environmental Conditions (RECs) early in the pre-development planning phase to avoid expensive construction delays, regulatory halts, and redesign costs.

Our team of certified environmental professionals brings deep industry knowledge and a meticulous approach to every project.

The Four Core Components of a Phase I ESA
Every assessment follows the rigorous four-pillar investigative protocol prescribed by ASTM E1527-21 and 40 CFR § 312.
Historical Research
We dig deep into city directories, historical aerial photographs, Sanborn fire insurance maps, and local deed records to uncover past land uses back to 1940 or initial development.
Site Reconnaissance
Our Environmental Professionals (EPs) walk the subject property and perimeter to identify visual signs of chemical spills, underground storage tanks (USTs), drums, pits, ponds, or PCB equipment.
Agency Review
We query federal (EPA NPL/CERCLIS), state (TCEQ LPST, VCP, IOP, hazardous waste), and local agency databases for known contamination releases on or near the subject property.
The Report
You receive a comprehensive, actionable report signed by an Environmental Professional (EP) clearly identifying any Recognized Environmental Conditions (RECs), CRECs, or HRECs.
Phase I Environmental Site Assessment FAQ
Clear answers to essential questions regarding environmental due diligence, turnaround windows, and risk management.
How long does a Phase I ESA take?
Typically 2 to 3 weeks. Rush services (5 to 10 business days) are available for tight closing deadlines, option expiration dates, and 1031 exchange requirements.
Does this include soil sampling?
No. Phase I is non-intrusive (observation, historical records, and interviews only). If we identify potential environmental risks or historical releases, we may recommend a Phase II ESA, which involves intrusive soil, groundwater, or vapor sampling.
What if a REC is found?
We provide clear, pragmatic recommendations. Often this leads to a targeted Phase II assessment to confirm or deny the presence of contamination, establishing definitive data for price negotiation, escrow holdbacks, or environmental insurance.
Subsequent Steps & Interconnected Due Diligence
When an acquisition requires complete environmental verification beyond historical research, Envirogyn deploys specialized field diagnostics to address specific physical contamination pathways.
Phase II ESA
Soil & groundwater sampling to physically verify or rule out contamination when a Phase I ESA identifies Recognized Environmental Conditions (RECs).
