What's My PFAS Responsibility?

Thanks to high-profile lawsuits and growing public awareness, many manufacturers and industry leaders are assessing their liability. Here's what you need to know.

Industry and Manufacturing

 

SOURCES OF PFAS

PFAS are a diverse group of compounds, which are resistant to heat, water, and oil. These properties have made PFAS ideal for use in hundreds of industrial applications and consumer products, including certain paper food packaging, firefighting foams, carpeting, apparel, and upholstery.

WHICH COMPOUNDS ARE REGULATED?

PFOA and PFOS get the most attention, but as of June 2020, at least 19 PFAS compounds are regulated or monitored across 23 states, 9 countries, and the European Union. The Interstate Technology & Regulatory Council (ITRC) maintains a table of water and soil values by state and country. This table is updated every couple of months as new rules are proposed or passed.

HOW DOES PFAS CONTAMINATION HAPPEN?

PFAS can enter the local water supply, ground and surface waters, soil, vegetation, and animal tissue through a variety of industrial sources.

Air Emissions

EPA researchers have found that point and non-point emissions can be a significant source of PFAS.

Wastewater

Discharges from industrial and municipal wastewater treatment plants can contaminate surface water.

Landfills thumbnail image

Landfills

Unlined and lined landfills have separate sources of PFAS concerns from direct contamination to leachate management issues.

AFFF

Aqueous Film-Forming Foam (AFFF) is great for putting out chemical fires, but it is a major documented source of PFAS contamination.

Agriculture thumbnail image

Agriculture

More than half of the domestic sewage sludge produced in the U.S. gets applied to agriculture as bio-solids.

 

PFAS TEST METHODS

Currently the EPA has only finalized test methods for drinking water, however, test methods for non-potable water and solids (soil, biosolids, plant and animal tissues, etc.) are under development.

STATE REGULATIONS FOR PFAS IN WASTEWATER

Wastewater regulators issue wastewater discharge permits under the National Pollutant Discharge Elimination System (NPDES) permit program.

This program has been around since the early 70s, but only recently have some states started to add PFAS to the permit requirements. The best way to stay abreast of changing NPDES requirements is to visit the applicable environmental regulatory agency's website for the latest information.

THE PROBLEM OF PFAS PRECURSORS

Although no US regulatory criteria have been established for PFAA precursors, concerns regarding their migration and transformation into PFAAs are growing. PFAA precursors can include compounds that originated in the original PFAS formulations or are polyfluorinated intermediate transformation products. The number of PFAA precursors quantifiable with commercially available analytical methods using LC/MS/MS is very limited.

To address this problem, the Total Oxidizable Precursor, or “TOP” Assay, was developed to better understand, and to a certain extent quantify, the mass of precursors that may be in an environmental sample. This test includes subjecting a sample through a strong bench-top oxidation step to mimic natural degradation processes and analyzing the sample pre- and post-oxidation. The mass balance is used to quantitate the amount of precursors in the sample.

SPECIAL PROJECTS: AIR & STACK EMISSIONS

Pace has a long history of sampling stack emissions and ambient air for a wide range of contaminants. We've leveraged our expertise to develop reliable methods for sampling and testing air and emissions for PFAS compounds.

The most common examples of air emissions testing for PFAS involve incinerator stack emissions from manufacturing and industrial sites. This requires specialized sampling equipment to be placed in the stack by qualified personnel. Samples are then tested using traditional PFAS by LC MS/MS Isotope Dilution methods. Not all labs that offer PFAS test methods are equipped to test stack emissions for contamination.

TRI PROGRAM ADDS 172 PFAS

The EPA's Toxic Release Inventory (TRI) program tracks the management of chemicals that may pose a threat to human health and the environment. As of January 1, 2020, 172 PFAS compounds were added to the program. The full list is available online.

The Pace Analytical® Regulatory Services team can provide assistance with TRI or other regulatory reporting requirements.

THE PFAS PROBLEM WON'T GO AWAY

With lawsuits proliferating, estimates for total industry liability run into the billions of dollars. Even if the contamination happened years ago, you could still be held liable as PFAS compounds do not break down naturally. A judge recently settled a lawsuit against a shoe manufacturer for nearly $70 million for PFAS contamination stemming from the 1960s.
