USEPA recently issued Effluent Guidelines Program Plan 15, which includes a focus on PFAS discharges from multiple categories. In conjunction with Plan 15, EPA has determined that revisions to the effluent guidelines and standards for the Landfills Category (40 CFR part 445) are warranted. See Section 6.3.3 of the Plan. Here are a few excerpts regarding landfill leachate:
Landfill leachate and wastewater treatment planning and resource information are available here.
From the USEPA to headlines in the media, coverage of PFAS moving from wastewater to drinking water is a major concern. Furthermore, there are growing concerns about how much PFAS is in by-products that are recycled or reused from waste products. Topping that list is fertilizer.
Retail fertilizer products made from at least 50% biosolids commonly sold to the general public and used in farming contain PFAS, which could get into crops and stock, eating those crops. The Environmental Protection departments in some states are beginning to consider or pass state-level specific regulations on the content of PFAS in biosolids.
The December 2022 USEPA memo to states (pages 4-5) made these recommendations on biosolids as follows:
Tony Kollasch, an environmental consultant specializing in remediation, tells us to use precaution and learn more about what plans are underway in your state. In his Wisconsin Agri-Business article, BIOSOLIDS and PFAS – NUTRIENTS with a SIDE OF CONCERN, he walks readers through the most recent reports and studies using plain language.
The issues and questions that come up are solvable. There are treatments for removing PFAS, and as an environmental engineering and consulting firm, we solve these types of challenges. We encourage the safe use of by-products and urge you to learn more about specific products by joining associations where you can educate yourself – it’s good for business and for understanding pending regulations that may impact your operations. It will help you run your business sustainably by making sound decisions based on human health, the environment, and economic demand.

Since the 1990s, USEPA has provided risk-based Regional Screening Levels (RSLs) to assist in evaluating environmental monitoring and contaminant levels – e.g., in soil, air, and water at residential and industrial properties. EPA periodically updates the RSL tables to reflect new contaminants of concern and new chemical toxicity data. The May 2022 RSL tables have been expanded to include 14 per- and polyfluoroalkyl substances (PFAS). PFAS are a large family of emerging contaminants that are garnering significant interest due to their significant toxicity and widespread use in industrial and consumer products such as fire-fighting foam, fabric treatment, and some food packaging. The latest EPA RSL tables are available at: https://www.epa.gov/risk/regional-screening-levels-rsls-generic-tables
Additional info regarding ongoing efforts to address and treat PFAS are available by searching this website: https://www.scsengineers.com/ and then using the filter to narrow down returns to your interests.
In a letter to Congress, SWANA and NWRA associations request that regulation under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) for addressing per- and polyfluoroalkyl substances (PFAS) contamination assign environmental cleanup liability to the industries that created the pollution in the first place. Both associations note that MSW landfills and solid waste management, an essential public service do not manufacture nor use PFAS. The industry, and ultimately the general public should therefore not be burdened with CERCLA liability and costs associated with mitigating PFAS from water and wastewater.

Re: Relief for Municipal Solid Waste Landfills from CERCLA Liability for PFAS
Dear Chairman Carper, Ranking Member Capito, Chairman DeFazio, Ranking Member Graves, Chairman Pallone, and Ranking Member McMorris Rodgers:
The municipal solid waste (MSW) management sector strongly supports the goal of addressing per- and polyfluoroalkyl substances (PFAS) contamination and holding accountable manufacturers and heavy users of these compounds. We are concerned, however, that regulation under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) instead would assign environmental cleanup liability to essential public services and their customers. We therefore request that Congress provide MSW landfills and other passive receivers with a narrow exemption from liability if certain PFAS are designated as hazardous substances under CERCLA. Doing so would keep CERCLA liability on the industries that created the pollution in the first place.
Context
• Landfills neither manufacture nor use PFAS; instead, they receive discarded materials containing PFAS that are ubiquitous in residential and commercial waste streams. MSW landfills and the communities they serve should not be held financially liable under CERCLA for PFAS contamination, as landfills are part of the long-term solution to managing these compounds.
• Landfills are essential public services that are subject to extensive federal, state, and local environmental, health, and safety requirements. Further, MSW landfills are important to managing and limiting PFAS in the environment, as recognized by the Environmental Protection Agency (EPA) in its December 2020 draft Interim Guidance on the Destruction and Disposal of [PFAS] and Materials Containing [PFAS].
• Just as certain airports are required by law to use firefighting foam containing PFAS, permitting authorities often require landfills to accept waste streams containing PFAS.
• Most landfills rely on wastewater treatment facilities for leachate management. Wastewater and drinking water facilities increasingly rely on landfills for biosolids management and disposal of PFAS-laden filters. Efforts to address PFAS at MSW landfills and drinking water and wastewater facilities must avoid disrupting this interdependence among essential public services to communities.
• Landfill leachate typically represents a minor proportion of the total quantity of PFAS received at wastewater treatment facilities from all sources. PFAS manufacturers or users, by comparison, contribute PFAS at levels that can be orders of magnitude higher than landfills.
Significant Economic Impacts
• Removing PFAS from landfill leachate requires advanced treatment techniques which are prohibitively expensive. Estimated capital costs to implement leachate pretreatment at a moderate-sized landfill to the extent necessary to significantly reduce PFAS range from $2 million to $7 million, with nationwide costs totaling $966 million to $6.279 billion per year for the solid waste sector. Trace concentrations of PFAS nevertheless would remain in leachate following pretreatment, exposing landfills to CERCLA liability.
• Absent relief from CERCLA liability, manufacturers and heavy users of PFAS compounds will bring claims for contribution against landfills and other passive receivers, generating significant litigation costs. EPA’s exercise of enforcement discretion will not insulate landfills from this litigation.
• These costs will be passed along to communities, water and wastewater treatment facilities, and biosolids management, all of which rely on the services of MSW landfills.
Broad Unintended Consequences
• CERCLA regulation will impel landfills to restrict inbound wastes and/or increase disposal costs for media with elevated levels of PFAS, including filters, biosolids, and impacted soils at Department of Defense facilities. The mere prospect of regulation in this area is already disrupting the interdependence of the drinking water, wastewater, and solid waste sectors.
• Food waste compost may contain PFAS due to contact with PFAS-lined packaging materials. As a result, a CERCLA designation could result in communities diverting food waste from organics recycling programs, hindering federal, state, and local climate and waste reduction goals.
• Cost increases likely will have a significant disproportionate impact on low-income households that rely on the affordability of services that the solid waste sector provides.
Recommendation
Although our sector is simultaneously pursuing “no action assurance” from EPA, the agency historically has been very hesitant to provide this relief given its policy that assurances should be given only “in extremely unusual cases.” As such, and acknowledging that EPA may have limited authority to act on our request, we recommend providing the following narrow exemption from CERCLA liability that affords relief to landfills and other passive receivers of PFAS1:
(a) IN GENERAL.—No publicly owned or operated community water system (as defined at 42 U.S.C. 300f), publicly owned treatment works (as defined at 33 U.S.C. 1292), or municipal solid waste landfill (as defined at 40 C.F.R. 258.2) shall be liable under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (42 U.S.C. 9601 et seq.) for the costs of responding to, or damages resulting from, a release to the environment of a perfluoroalkyl or polyfluoroalkyl substance designated as a hazardous substance under section 102(a) of such Act that resulted from the discharge of effluent, the disposal or management of biosolids, the disposal of filtration media resin, or the discharge of leachate where such actions are in compliance with Federal or State law and all applicable permits.
(b) EXCEPTION.—Subsection (a) shall not apply with respect to any discharge described in such subsection that results from any gross negligence, willful misconduct, or noncompliance with any Federal or State law or permit governing the discharge of effluent, disposal or management of biosolids, disposal of filtration media resin, or waste disposal.
Thank you for your consideration of our request, and we look forward to continuing to partner with the federal government to ensure the safe and effective management of waste streams containing PFAS.
Sincerely,
National Waste & Recycling Association
Solid Waste Association of North America

EPA Requires Reporting on Releases and Other Waste Management of Certain PFAS, Including PFBS
As part of EPA’s Strategic Roadmap, the Agency announced the automatic addition of four per- and polyfluoroalkyl substances (PFAS) to the Toxics Release Inventory (TRI) list.
As of January 1, 2022, facilities that are subject to reporting requirements for these chemicals should start tracking their activities involving these PFAS as required by Section 313 of the Emergency Planning and Community Right-to-Know Act. Reporting forms for these PFAS will be due to EPA by July 1, 2023, for the calendar year 2022 data.
In April 2021:
EPA previously updated the Code of Federal Regulations with PFAS that were added to the TRI on January 1, 2021, under section 7321(c) of the NDAA and regulated by an existing significant new use rule (SNUR) under the Toxic Substances Control Act (see 40 CFR 721.10536).
In addition to continuing to add PFAS to the TRI, the EPA will soon announce a series of PFAS test orders requiring PFAS manufacturers to provide the Agency with toxicity data and information on PFAS.
If you have questions or concerns about reporting requirements, contact one of our environmental chemistry – hazardous materials/waste professionals at .
Anna Cerf conducted research at the Environmental Research and Education Foundation, had an internship at the Environmental Defense Fund, and worked for SCS Engineers. Now she’s off to Germany.
Cerf graduated from UVA in 2020 with a degree in civil engineering and a minor in urban and environmental planning. The course work for her program will cover three fundamental disciplines: sanitary engineering, groundwater remediation, and hydraulic engineering.
She is a Rotary Global Grant Scholar, using an award to fund her two-year master’s program in water resource engineering and management at the University of Stuttgart. “With the support of ISWA professors and access to University of Stuttgart’s premier research facilities, I will research the transport and treatment of emerging contaminants for my master’s thesis.”
Cerf feels having a master’s in water resource engineering and management will further her career at the intersection of environmental issues and public health. “The University of Stuttgart has top-of-the-line water research facilities,” Cerf said. “It is also home to the Institute of Sanitary Engineering, Water Quality, and Solid Waste Management.
“By the end of the program, I will be able to anticipate, understand and evaluate water management-related issues,” Cerf said. “As climate change exacerbates existing water scarcity issues and environmental degradation damages water quality, these skills become increasingly important.”
