Nationwide coverage · Custom quote in 1 hour · ASTM E1528 compliant
Fill out our quick form with your property address. We review the details and send you a custom quote within 1 hour — along with a straight answer on whether a TSA is the right product for your deal.
Our environmental professionals run the regulatory database review and historical records research, then visit the property in person — the site visit that distinguishes a TSA from a desktop screen.
You receive an ASTM E1528 Transaction Screen report identifying any Potential Environmental Concerns (PECs). If PECs surface, we will walk you through upgrading to a Phase 1 ESA for CERCLA liability protection.
A TSA is one of three levels of environmental due diligence A3 Environmental offers. It is worth seeing it side by side — for many transactions, a faster RSRA or a more protective Phase 1 ESA is the better value.
"We were running up against some deadlines, and they jumped through hoops to get everything completed on time."
"The A3E team did a great job on our Phase 1 report. They were quick, thorough and professional."
"They were able to give me all of the information that I needed. Highly recommend A3 Environmental."

A Transaction Screen Assessment (TSA) is a form of environmental due diligence that sits between a Record Search with Risk Assessment (RSRA) and a full Phase 1 ESA. It follows the ASTM E1528 standard and, in practice, is essentially an RSRA with a physical site visit added on. A TSA combines a regulatory database review, historical records research, a standardized owner/occupant questionnaire, and an in-person inspection by an environmental professional — producing a report that flags Potential Environmental Concerns (PECs) at the property.
The most important difference is legal. A Phase 1 ESA performed to ASTM E1527-21 satisfies the federal "All Appropriate Inquiries" requirement and establishes the innocent landowner and bona fide prospective purchaser defenses under CERCLA. A TSA does not. That means a Transaction Screen identifies Potential Environmental Concerns rather than the Recognized Environmental Conditions (RECs) of a Phase 1 ESA, and it does not carry the liability protection that buyers and lenders often assume they are getting. If a PEC is found, the typical next step is to upgrade the TSA into a Phase 1 ESA to obtain that protection.
We will be candid, because it is your money. A TSA costs more than an RSRA, takes about as long as a Phase 1 ESA (because of the site visit), and provides the same CERCLA liability protection as an RSRA — which is none. For that reason, many buyers are better served by one of two alternatives: a Record Search with Risk Assessment (RSRA) when speed and cost are the priority, or a Phase 1 ESA when liability protection actually matters for the transaction. A TSA still makes sense in specific situations — for example, when a particular lender or SBA program explicitly asks for a Transaction Screen — and when it does, we perform it to ASTM E1528 standards. When you request a quote, we will tell you honestly which product fits your deal.
Every A3 Environmental TSA begins with a regulatory database review at the federal, state, county, and municipal level, paired with historical records research — aerial photographs, fire insurance maps, and city directories. Our environmental professionals then visit the property in person, completing the standardized ASTM E1528 questionnaire and documenting site conditions. The final deliverable is a written Transaction Screen report identifying any PECs, with clear next-step recommendations. We serve commercial property owners, buyers, and lenders nationwide — coast to coast across the continental United States — backed by deep Midwest roots and a 4.9★ Google rating since 2015.
