For commercial property owners, PFAS risk rarely stays confined to a single laboratory result. It can affect due diligence, financing, redevelopment plans, and potential environmental liability, especially along the Texas Gulf Coast and Alabama Gulf Coast industrial corridor.
The PFAS regulatory landscape is a moving combination of federal requirements, state agency oversight, and site-specific due diligence. Owners should review historical property uses, identify potential PFAS sources, and evaluate applicable requirements with qualified environmental professionals before buying, selling, developing, or refinancing a property.
A practical review starts by separating the rules that apply nationwide from the requirements administered by agencies such as the Texas Commission on Environmental Quality and the Alabama Department of Environmental Management. That distinction helps clarify what changing federal actions may mean for a specific site and sets the stage for understanding the regulatory framework.
Understanding the PFAS Regulatory Landscape
PFAS, or per- and polyfluoroalkyl substances, is not one chemical. It is a broad family of fluorinated compounds used in products and industrial processes because they resist heat, water, oil, and chemical degradation. The size of that family depends on the definition being applied. A CAS analysis identified approximately 24 million distinct molecules under the broader OECD definition, while the more stringent EPA definition identified approximately 1.8 million compounds. These figures help explain why PFAS compliance cannot be reduced to testing for one substance or relying on one regulatory list.
Federal drinking-water standards are moving from guidance to enforceable requirements
The EPA finalized a National Primary Drinking Water Regulation for certain PFAS, including enforceable limits for PFOA and PFOS. Although the rule applies directly to public water systems, it matters to property owners whose sites use, store, manufacture, or may have released these compounds. A suspected release can affect due diligence, site investigation decisions, financing, and the potential cost of future corrective action. The EPA’s implementation materials describe the regulation and its compliance framework at EPA.gov.
Reporting duties can reach historical activity
TSCA Section 8(a)(7) adds another layer. Manufacturers and importers that manufactured or imported PFAS, or PFAS-containing articles, in any year since January 1. 2011, must electronically report information about uses, production volumes, disposal, exposures, and hazards. This requirement is relevant during ownership transfers and facility reviews because historical operations may create documentation and compliance questions even when a current owner did not conduct the original activity. The EPA’s TSCA reporting guidance explains the rule’s scope.
Rules can change before a transaction closes
The landscape remains unsettled. The EPA has proposed rescinding drinking-water regulations for PFHxS, PFNA, HFPO-DA, commonly known as GenX, and the Hazard Index mixture involving those compounds and PFBS. A proposal is not the same as a final rule, so property owners should avoid treating regulatory change as a reason to defer investigation. Instead, evaluate historical uses, records, adjacent sources, and applicable federal and state requirements as part of environmental due diligence. A current, documented review provides a stronger basis for managing investment and compliance risk.
Recent EPA Actions Shaping PFAS Regulation
The federal approach is moving beyond a single drinking-water rule toward lifecycle management, data collection, cleanup, and financial accountability. For property owners, that shift means PFAS due diligence cannot stop at checking whether a site currently exceeds an enforceable limit. Historical operations, waste handling, wastewater discharges, biosolids applications, and potential off-site migration may all affect future obligations and property risk.
A broader strategy with new state funding
In May 2026, the EPA announced a holistic strategy addressing PFAS across the full lifecycle, from production and use through treatment and disposal. The agency also announced nearly $1 billion in new funding for states to address PFAS in drinking water and said it would advance treatment and destruction technologies. The same strategy included proposed rules that uphold the National Primary Drinking Water Standards for PFOA and PFOS. Those standards establish enforceable limits for the two compounds, although implementation timing and practical requirements remain important to track. Review the EPA’s key PFAS actions and implementation updates before making a transaction or compliance decision.
Monitoring is expanding before every contaminant is regulated
In June 2026, EPA proposed the Sixth Unregulated Contaminant Monitoring Rule, or UCMR 6. The proposal would require monitoring for 30 contaminants that are not currently regulated but may occur in drinking water. Monitoring does not automatically create a cleanup standard or an immediate property-wide testing mandate. It does, however, expand the data regulators and water systems can use when evaluating future requirements. Owners of facilities near public water supplies, industrial users, and potentially affected commercial sites should preserve sampling records and understand how water-system monitoring could reveal a historical source.
Biosolids and manufacturer liability add new scrutiny
In July 2026, EPA released draft guidance intended to help wastewater utilities, landowners, and the public reduce risks from PFOA and PFOS in biosolids. Landowners who receive or have received biosolids should document application areas, vendors, dates, and supporting analytical records while the guidance develops.
EPA, the U.S. Department of Justice, and the West Virginia Department of Environmental Protection also announced a landmark Chemours settlement in June 2026. The agreement includes more than $450 million in penalties and relief tied to PFAS pollution in three states. Although a manufacturer settlement does not automatically assign liability to every neighboring owner. It reinforces the financial and enforcement consequences of releases and the importance of tracing historical sources.
These actions change the practical compliance question for property owners. Rather than asking only whether a current limit applies, owners should identify PFAS-related activities, maintain defensible records. Evaluate recognized environmental conditions, and obtain qualified environmental advice before acquisition, redevelopment, refinancing, or material changes in operations.
PFAS Regulation in Texas and Alabama: What Property Owners Should Know
State action is a major part of the PFAS regulatory landscape. A scoping review identified 454 relevant PFAS policy documents, including 181 focused on U.S. state-level policy. That emphasis matters for property owners because obligations, agency expectations, and investigation priorities can differ even when a facility operates within the same industrial sector.
| Factor | Federal (EPA) | Texas (TCEQ) | Alabama (ADEM) |
|---|---|---|---|
| Drinking water standard | PFOA/PFOS enforceable limits | State monitoring programs active | ADEM monitoring under Title 22 |
| Reporting obligation | TSCA 8(a)(7) since 2011 | TCEQ enforcement authority | ADEM permits and reporting |
| Enforcement scope | National framework | Gulf Coast industrial corridor | Mobile and I-10 corridor |
| Due diligence tool | Phase I ESA per ASTM E1527-21 | Site history and agency records | ADEM file review recommended |
Texas: TCEQ oversight and monitoring
In Texas, the Texas Commission on Environmental Quality (TCEQ) is the primary state environmental regulator. Its enforcement authority can affect facilities with potential releases, reporting gaps, or noncompliance involving regulated environmental media. TCEQ PFAS monitoring programs also help build the state’s understanding of where these compounds may occur and which sites may warrant additional attention.
For owners and buyers along the Texas Gulf Coast, this creates a practical due diligence issue. A historical review should consider the property’s prior industrial uses, nearby potential sources, fire-training or firefighting activities, waste handling, and available agency records. A Phase I Environmental Site Assessment can identify recognized environmental conditions that may justify further evaluation, but it is not a pass-or-fail report. The appropriate follow-up depends on the property’s history and current regulatory context.
Alabama: ADEM and Title 22 requirements
Alabama administers environmental law through the Alabama Department of Environmental Management (ADEM), operating under Title 22 of the Code of Alabama. Property owners and facility operators in Mobile and the surrounding industrial corridor must account for ADEM’s permitting, inspection, reporting, and enforcement framework when evaluating potential PFAS concerns. State requirements and agency processes can add a separate layer of review beyond federal developments.
That state-specific complexity can make a transaction or compliance decision harder to manage without local guidance. Projexiv Environmental understands the regulatory environments in both Texas and Alabama and can help connect records review, site history, agency considerations, and follow-up recommendations. For a commercial acquisition or operating facility, that local perspective supports a more defensible risk-management plan while standards and monitoring priorities continue to evolve.
The PFAS regulation scoping review provides additional context on the breadth of state-level policy activity in the United States.
How PFAS Affects Phase I Environmental Site Assessments
PFAS concerns have made historical research an increasingly important part of commercial property due diligence. ASTM E1527-21, the current Phase I Environmental Site Assessment standard, recommends reviewing the property’s historical uses for potential PFAS-related activities. That review can help identify whether past operations, adjacent properties, storage areas, or waste-handling practices warrant closer attention.
Why historical use matters
A Phase I ESA is not a pass-or-fail inspection. It evaluates available records, historical maps, regulatory databases, site conditions, and interviews to identify recognized environmental conditions (RECs). For a property that previously housed manufacturing, metal finishing, firefighting training, airports, landfills, or other activities that may involve PFAS. The environmental professional can use that information to determine whether additional investigation is appropriate.
This does not mean every property with a possible PFAS connection requires immediate sampling. It means the risk should be identified, documented, and evaluated in context. Because PFAS standards and agency expectations continue to change, a well-supported historical review gives buyers, sellers, lenders, and attorneys a clearer basis for deciding what to do next.
Supporting CERCLA liability protection
Phase I ESAs remain the primary tool for evaluating environmental risk and potential PFAS liability during a commercial property transaction. Completing appropriate due diligence can support the CERCLA innocent purchaser defense, provided the purchaser also satisfies the other applicable requirements, including appropriate care and cooperation after acquisition. It is not a guarantee of protection, but skipping the assessment can leave a buyer with fewer defensible records about what was known before closing.
Lenders commonly require an ASTM-compliant Phase I ESA before approving commercial real estate financing. Projexiv Environmental provides bank-approved Phase I reports with a typical 10-day turnaround, helping transaction teams address environmental questions without unnecessary delays.

Protecting Your Property Investment: Managing PFAS Liability
PFAS liability is easier to manage when environmental due diligence begins before a transaction closes or a facility changes operations. Commercial property owners should treat the evolving PFAS regulatory landscape as an ongoing risk-management issue, not a one-time paperwork requirement. A proactive approach helps identify potential concerns, document reasonable steps, and reduce surprises that can affect financing, redevelopment, or resale.
Build a documented environmental baseline
- Review the property’s historical uses, former occupants, manufacturing processes, waste-handling practices, fire-suppression activities, and nearby facilities that may have used PFAS-containing materials.
- Conduct a Phase I Environmental Site Assessment as the primary due-diligence tool for evaluating environmental risk and potential PFAS liabilities.
- Identify recognized environmental conditions and determine whether additional investigation is warranted.
- Use the assessment findings to make informed decisions about follow-up testing, controls, and contractual protections.
Keep the assessment, sampling records, permits, waste manifests, corrective actions, and communications in an organized compliance file. This documentation gives lenders, buyers, regulators, and future consultants a clear record of how environmental risks were evaluated and managed.
Turn findings into an operating plan
Where PFAS concerns are identified, assign responsibility for monitoring regulatory changes, maintaining controls, reviewing new analytical data, and updating procedures. An environmental compliance plan can connect those tasks with broader air, stormwater, waste, and reporting obligations. Comprehensive plans help owners respond as federal and state requirements become more complex, while reducing the risk that an important deadline or operational safeguard is missed.
Review the plan whenever the property changes ownership, tenants, processes, suppliers, or waste streams. Proactive due diligence will not eliminate every environmental risk, but it can protect investment value by replacing uncertainty with documented, repeatable controls. For property-specific guidance, contact Projexiv to discuss an assessment or compliance plan before the next transaction or operational change.
Frequently Asked Questions
What should commercial property owners watch in the PFAS regulatory landscape?
Owners should track federal drinking water requirements, reporting obligations, and state enforcement priorities. The EPA has established enforceable limits for PFOA and PFOS under its National Primary Drinking Water Regulation. While TSCA Section 8(a)(7) requires certain manufacturers and importers to report PFAS-related uses, production, disposal, exposure, and hazard information for activity since January 1, 2011. EPA drinking water guidance and TSCA reporting guidance provide the controlling details.
Why is PFAS compliance difficult for commercial properties?
PFAS compliance is difficult because the chemical group includes many compounds, regulatory requirements are changing, and a property’s historical operations may not reveal every potential source. Owners also must evaluate how environmental conditions, tenant activities, supply chains, and applicable state requirements affect the site’s risk. A documented review is more reliable than assuming that a property is unaffected because PFAS was not part of its current operations.
How can a Phase I ESA help identify PFAS-related property risk?
A Phase I Environmental Site Assessment is the standard due diligence tool for evaluating environmental conditions and potential PFAS liabilities in a commercial transaction. It can review historical uses, surrounding properties, records, and recognized environmental concerns that may warrant additional investigation. Projexiv Environmental identifies ESAs as a primary tool for mitigating potential PFAS contamination liability, although a Phase I ESA does not by itself determine whether PFAS is present.
Do Texas and Alabama property owners follow the same PFAS requirements?
No. Federal requirements may apply in both states, but state agencies can establish different investigation, cleanup, permitting, reporting, and enforcement expectations. Texas property owners should monitor TCEQ requirements, while Alabama owners should review applicable Alabama Department of Environmental Management requirements. Site history and the property’s location determine which obligations and agency processes matter.
What practical step should an owner take when PFAS risk is possible?
Start with a documented environmental due diligence review, then determine whether sampling, regulatory consultation, or a compliance plan is appropriate. Preserve historical records, identify current and former industrial activities, and address findings before refinancing, purchasing, selling, or changing site operations. Proactive environmental management plans can help owners navigate changing state and federal requirements and protect investment value, according to Projexiv Environmental.
