PFAS Wastewater Survey Delay Slows EPA Rules

The PFAS wastewater survey has become a key test of how quickly federal regulators can build national evidence for controlling industrial discharges, treated sewage solids and wastewater plant contamination. As of September 7, 2026, the proposed nationwide study remained under White House review, almost two years after the U.S. Environmental Protection Agency submitted the information collection request in October 2024.

The delay is not, by itself, a final policy decision. It is a procedural bottleneck around data collection. Yet its practical effect is larger than paperwork: without comparable national sampling, EPA has less evidence for ranking industrial sources, writing consistent pretreatment rules, or deciding how PFAS in biosolids should be managed before land application.

Why The PFAS Wastewater Survey Matters

What The PFAS Wastewater Survey Would Measure

The proposed study, often described as the POTW Influent PFAS Study, would examine publicly owned treatment works across the United States. The plan described in reporting would sample hundreds of municipal wastewater treatment plants for PFAS concentrations in influent, effluent and biosolids, according to Wastewater Digest. Those categories matter because they trace contamination before treatment, after treatment, and in treated sewage solids that may later be managed or applied to land.

Municipal plants are not generally the original manufacturers of PFAS. They receive waste streams from households, businesses and industries. That makes them a central collection point but also a difficult regulatory target. If the federal government lacks sector-by-sector data, it becomes harder to decide whether the main regulatory pressure should fall on upstream industries, plant operators, biosolids management, or some mix of all three.

Why The Review Timeline Is Unusual

The information collection request was submitted to the White House Office of Management and Budget in October 2024. As of early September 2026, it remained under review, a period that reporting described as far longer than the roughly 60-day review period typical under the Paperwork Reduction Act. Former EPA officials told The Washington Post that the delay had stalled the nationwide effort.

That does not prove why the review has lasted so long. The confirmed point is narrower: the request had not been approved by early September 2026, so the national sampling program had not moved forward as proposed. In regulatory terms, the lost time is significant because wastewater rules often depend on data that can survive technical, legal and economic scrutiny.

Regulatory Gaps Left By The Delay

Industrial Discharge Limits Need Comparable Data

One stated goal of the study is to identify the top industrial sectors responsible for PFAS discharges. Former EPA Office of Water Director Robert Wood has said that once regulators know the top one, two or three sectors, they can begin rulemaking to set nationwide discharge limits. That sequence shows why the data question sits before the rulemaking question.

Without PFAS wastewater survey data, EPA and state regulators must rely more heavily on uneven state and local monitoring. Those datasets can be useful, and some utilities argue they are already enough to support action. Still, they may not provide the same nationwide basis for ranking industries, comparing regions, or setting uniform pretreatment standards that apply consistently across state lines.

The regulatory stakes extend beyond conventional wastewater permits. If industrial sectors are identified as significant contributors, EPA could have a stronger foundation for source controls before PFAS reaches municipal plants. That would matter for treatment costs because municipal systems can become downstream managers of pollution they did not create.

Biosolids Guidance Has A Data Problem

Biosolids are a central concern because treated sewage solids can carry PFAS into soils and related waste streams. Research notes indicate that EPA officials have faced criticism that prior biosolids risk assessments did not include national PFAS occurrence data in biosolids. The unresolved issue is circular: the survey that could supply such national data remains unapproved and unpublished.

In July 2026, EPA released draft guidance on managing PFOA and PFOS in biosolids to reduce risks from land application. Draft guidance is not the same as a binding national discharge rule. It can help agencies and utilities think through risk, but it does not replace a national dataset that shows where PFAS is occurring, at what concentrations, and from which contributing sectors.

In May 2026, EPA also rolled back some Biden-era drinking water regulation limits affecting six PFAS chemicals for public water systems. That action was separate from the wastewater survey, but it adds to the uncertainty around how the agency will align drinking water, wastewater, industrial pretreatment and biosolids policy.

State Action And The Patchwork Risk

Michigan Shows One State-Level Path

Some states have not waited for the federal survey. Michigan has collected data from wastewater plants and required industries to reduce PFAS discharges into plants so river and lake limits can be met. Reporting cited in the research notes says that approach has led to substantial reductions in PFAS releases at the state level.

Michigan’s experience suggests that state-led monitoring and source reduction can produce results. It does not prove that every state has the same resources, legal tools or industrial profile. A federal program would be aimed at producing a more consistent baseline across the country, while state programs reflect local priorities and capacity.

The delayed PFAS wastewater survey therefore raises a federalism problem as well as a scientific one. States may keep moving at different speeds, with different discharge thresholds, monitoring requirements and enforcement practices. That can push industry, utilities and communities into a patchwork system rather than a unified national framework.

Utilities Do Not Share One View

Wastewater agencies and utilities are not described as having one position. Some support collecting new nationwide data before broader federal rulemaking. Others, including the National Association of Clean Water Agencies, argue that existing state and local monitoring has already produced enough information to act.

That split reflects a real policy tension. Waiting for national data may improve the technical basis for future regulation, but it also prolongs a period in which PFAS can continue moving through water, soil and waste streams. Acting on existing data may reduce exposure sooner, but it can invite disputes over whether rules are supported by a consistent national record.

Industrial source questions also reach sectors that are not always part of the public wastewater debate. EarthTimes has separately covered concerns about PFAS data centers and EPA chemical review, a reminder that PFAS policy cuts across wastewater, cooling, fire systems, chemical approvals and disposal pathways.

  • Confirmed: EPA submitted the information collection request in October 2024.
  • Confirmed in reporting: the request remained under White House review in early September 2026.
  • Unresolved: when OMB will complete review, whether the survey will proceed as proposed, and how EPA would use the results in binding rules.

PFAS Wastewater Survey Delay And Future Rules

What Regulators Can And Cannot Say Yet

The strongest policy argument for the survey is that national wastewater regulation needs a defensible record. Federal discharge limits and pretreatment standards must identify sources, show why controls are needed, and support decisions across many types of facilities. The PFAS wastewater survey would not answer every scientific question, but it would help establish which industrial sectors deserve priority attention.

The strongest argument against waiting is that PFAS accumulation may continue while agencies debate data needs. Critics, including environmental groups and former EPA officials, say delay can increase public exposure and long-term remediation costs. The research notes identify possible exposure pathways through drinking water, soil, food crops and land-applied biosolids, but the pending survey means the national occurrence picture remains incomplete.

For future regulation, the key distinction is between guidance, monitoring and enforceable limits. Draft guidance for biosolids can shape decisions, but it does not create the same nationwide obligations as discharge standards. State monitoring can identify local sources, but it may not settle national sector rankings. A White House review can be procedural, but a two-year pause changes the timing of every later regulatory step.

For this issue, the central evidence remains the same: the survey request exists, it has not been cleared as of September 7, 2026, and the absence of national data is shaping what EPA can credibly do next.

The delay leaves EPA with a narrower set of tools than a completed national sampling program would provide. It can issue draft guidance, assess existing state and local data, and consider narrower actions. What it cannot yet cite is the unpublished nationwide evidence base that the proposed study was designed to create.
