In environmental protection, the battle against invisible threats often goes unnoticed by the public eye. Yet, recent PFAS regulatory updates presented by the U.S. Environmental Protection Agency (USEPA) have brought a crucial contender into the spotlight: per- and polyfluoroalkyl substances (PFAS). These synthetic chemicals, omnipresent in our daily lives—from non-stick cookware to firefighting foams—have raised concerns due to their environmental persistence and potential health risks.
With the USEPA’s recent Publicly Owned Treatment Works (POTW) Influent Study under Effluent Guidelines Program Plan 15, Toxic Substances Control Act (TSCA) PFAS reporting requirements, proposed rule under the Resource Conservation and Recovery Act (RCRA), the release of two PFAS testing methods, understanding PFAS has never been more critical.
At EnviroScience, we are at the forefront of this emerging field, bolstered by the expertise of our Senior Environmental Toxicologist, Kevin Custer, Ph.D.
Understanding PFAS in Layman’s Terms
Imagine chemical substances so persistent that they don’t break down in nature—that’s PFAS for you. These PFAS chemicals are unique due to their carbon-fluorine bonds. They are found in countless consumer products and are known for their oil, water, grease, and heat-resistant properties.
These “Forever Chemicals” have a knack for sticking around in our environment and bodies, causing adverse human health effects such as liver and kidney cancers, as well as thyroid, reproductive, and developmental effects.
Recognizing the risks, the USEPA is taking steps toward regulatory updates to safeguard our water and soil from contamination.
Enter EnviroScience PFAS Expert Dr. Kevin Custer
EnviroScience prides itself on having a team of dedicated experts like Dr. Kevin Custer, an aquatic ecotoxicologist and a PFAS subject matter expert. Dr. Custer’s career journey from the U.S. Department of Agriculture-Natural Resources Conservation Service to EnviroScience showcases a deep commitment to understanding and mitigating environmental contaminants.
Dr. Custer’s work—particularly in aquatic environments—positions EnviroScience uniquely to address the challenges posed by PFAS through comprehensive field sampling, data analysis, and compliance strategies.
What the Newly Proposed PFAS Regulatory Updates Mean
Recently, the USEPA entered into the Federal Register its intent to submit an Information Collection Request to the Office of Management Budget for the POTW Influent PFAS Study under Effluent Guidelines Program Plan 15. Under the POTW Influent PFAS Study, the USEPA will perform a two-phased approach to sample 200-300 of the highest flow POTWs and up to 2000 Industrial Users (IUs) in the U.S. The study will test the POTW influent, effluent, sludge/biosolids, and IU effluent using Method 1633 and Method 1621. The public comment period closes on May 28, 2024.
The USEPA has updated the definition of a PFAS chemical substance in TSCA Section 8(a)(7), and the chemical substance must meet one of three defined PFAS chemical structural definitions found in this rule. These PFAS reporting requirements under this rule are for TSCA chemical substances that were manufactured going back to 2011.
The USEPA has identified 1,462 PFAS from the known TSCA universe that have been manufactured or in commerce since 2006, including any chemicals submitted under the USEPA’s TSCA New Chemicals Program. There are specific entities that are required to report under TSCA. If an entity falls under TSCA reporting requirements, there are a couple of important items to note under this rule: no reporter exemptions and no minimum volume/concentration exemptions.
The USEPA proposed rulemaking to designate nine PFAS under RCRA because studies are showing toxic and adverse health effects on humans and animals from PFAS exposures. This proposed rule will potentially affect hazardous waste treatment, storage, and disposal facilities with solid waste management units. The public comment period closes on April 8, 2024, so watch for updates as the USEPA moves this proposed rule forward.
The USEPA’s actions signal a shift towards stricter oversight and management of PFAS. This means adapting to new testing protocols and potentially reevaluating waste management practices for industries and municipalities. The release of Method 1633 allows for the quantification of up to 40 PFAS compounds in a host of environmental matrices. While Method 1621 serves as a screening tool, this method indicates if organofluorines (carbon-fluorine bonds) are present in water and wastewater. Together, these methods guide stakeholders in identifying and addressing PFAS presence.
