EPA Should Use U.S. Chemical Safety Law to Turn Off PFAS Tap

The word

PFAS is a group of synthetic chemicals used in industrial processes and consumer products, including water-repellent clothing, such as outdoor wear, and food packaging. Once these “forever chemicals” are produced and used, they often make their way into the environment and our bodies. Many pose serious threats due to their toxic effects (often at trace levels) and their ability to build up in people, animals and the environment. Studies show that they are in almost all of us.

To make matters worse, people are exposed to multiple PFAS, not individual PFAS in isolation. Yet under the nation’s primary chemical safety law, EPA evaluates the safety of PFAS chemicals one at a time and does not consider the combined risks from exposures to multiple PFAS. Combined exposures increase the risk of harmful effects, thus magnifying the risks and the need for action.

Current Situation: All Costs, No Benefits

PFAS move easily throughout the environment and are difficult to destroy. They have contaminated drinking water, food, farms, wildlife, and the environment more broadly. At the local, state and federal levels, the U.S. is spending millions of dollars to clean up PFAS contamination. Some states, such as Michigan and Maine, are trying to recoup the costs their residents have had to bear to clean-up PFAS contamination of their water and land. The federal government is also taking action to address the widespread PFAS contamination. The costs for cleaning up PFAS contamination are imposed on society by the domestic producers, importers and users of PFAS who profit from their production and use.

Yet, despite the well-documented risks and costs to society of these chemicals, companies still continue to produce, import, and use PFAS. It is time to ban all PFAS or—if there are truly essential uses for these chemicals—limit how they are produced, imported and used so that their impact on us and the environment is minimal.

Urgent Need: Revisit, Reassess, and Regulate All PFAS

While EPA has recently tightened up approvals for new PFAS entering the market, it has yet to take significant action on those that are already on the market, which includes the hundreds of PFAS the agency approved over the past few decades. It is clear these PFAS have not been produced responsibly as demonstrated by the environmental contamination associated with many of the PFAS manufacturing facilities. And yet, many of these PFAS are still on the market. They are being produced and released into the environment, are in products we use every day, and continue to contaminate us and our environment.

Many of EPA’s approvals were made 10 to 20 years ago, before we had a full picture of the pervasiveness and degree of PFAS contamination. The data on the extent of the environmental contamination of these persistent PFAS, their ability to move through the environment, and the significant difficulty in destroying them was not as robust as it is today. Furthermore, mounting evidence shows that even trace levels of PFAS can cause developmental issues in children, reduced fertility, hormonal disruptions, and certain types of cancer.

In addition, these approvals did not consider risks to vulnerable groups, such as pregnant women and children as currently required by the law. Many communities are exposed to multiple PFAS, particularly those who live, work and play near where PFAS are made and used.

Addressing the production, import and use of PFAS would limit further pollution of our water supplies, safeguard the health of our communities, and be consistent with other strong EPA actions to address PFAS, including its recent robust proposed drinking water standards.

Effective regulation of these harmful chemicals at their source would also accelerate efforts to seek out and adopt safer alternatives. Leaving chemicals with such well-documented harms on the market makes it more difficult for innovative, safer substitutes to enter it. Failing to address these risks in effect puts a thumb on the scale in support of older harmful technologies.

Our Take

EPA should re-evaluate each of the PFAS it has approved. During that re-evaluation, EPA should use the best available science and consider the full picture of PFAS exposure. Considering each PFAS in isolation rather than the multiple PFAS people, particularly those in vulnerable groups, are exposed to will underestimate their risk.

EPA should use the Toxic Substances Control Act to take action to ban these legacy PFAS, or restrict them if the uses are truly essential, rather than continuing to allow the production, import and use of these demonstrably harmful “forever chemicals.”

FDA’s squishy definition of adverse health effects of substances in food

Maricel Maffini, consultant, and Tom Neltner, Senior Director, Safer Chemicals

3 human figures showing stages of becoming ill. First figure is all white and standing up straight. Second figure is bent over and stomach area is red. Third figure is is all red, bent over, and appears to be vomiting.

What Happened

A recent peer-reviewed publication criticized FDA’s criteria for identifying adverse health effects associated with exposure to pathogens, chemicals, or allergens in foods. The authors gave two recent examples of the agency dismissing health concerns: a toxin created in spoiled fish that caused temporary, medically adverse health effects because they were short-term and reversible, and an additive where evidence from animal testing showed harm in only one sex. The authors concluded that the agency’s criteria are “inadequate because they are not science-based.”

Why It Matters

FDA is responsible for protecting food safety and the public’s health. In order to do that, it makes decisions whether a pathogen, chemical, or allergen causes an adverse health effect that must be avoided—so the agency’s definition of an adverse health effect is critically important. Unfortunately, FDA lacks a clear definition of the term, usually approaching it on a case-by-case basis in a manner that lacks transparency and scientific grounding.

Adverse Effects Dismissed by FDA

In 2020, the director of The Pew Charitable Trusts’ food safety project argued that FDA failed to “protect Americans from preventable illnesses” because it considered that the effects caused by the fish toxin were temporary or reversible. FDA described the toxin’s effects, which ranged from facial flushing and sweating, dizziness, nausea and headache to more severe cases of blurred vision, respiratory stress, and swelling of the tongue. The Pew director reasonably added that people may require hospitalization, medical treatment due to cardiac complications, and altered blood pressure–all of which are adverse health effects.

In a 2019 final rule approving the listing of leghemoglobin as a color additive, the Center for Food Safety objected that FDA dismissed statistically significant “changes in blood chemistry, blood clotting ability, and blood globulin values” as potential health effects. In its response to the objection, the agency argued that “statistical differences seen between control animals and treatment animals due to small changes in the value of the parameter are not likely to be of biological or toxicological significance.” FDA further stated that for the color additive to cause the blood changes to be “potentially adverse” it should:

  • Show a “clear dose-response,” described as a direct relationship between the dose given and the effect observed, in other words, the higher the dose, the higher the effect; and
  • Be observed in both sexes of the species in which the substance is tested.

This argument put forth by FDA’s food safety scientists would be summarily dismissed by their colleagues on the drug side because it ignores current scientific principles: dose responses can have different shapes and there are known sex differences in response to exposures from multiple chemicals.

Our Take

This is an ongoing issue. Other organizations have defined “adverse health effects.” For example, EPA’s Integrated Risk Information System (IRIS) defines adverse effect as “[a] biochemical change, functional impairment, or pathologic lesion that affects the performance of the whole organism, or reduces an organism’s ability to respond to an additional environmental challenge.”

FDA’s lack of a practical definition for adverse health effect and how the agency applies it in food safety assessments has likely contributed to inconsistencies in its decision making.

Next Steps

We will continue to press the agency for transparency about what health effects it considers important to prevent and protect the health of American families. FDA should publish clear, rational, science-based criteria for determining adverse effects and periodically review them as our knowledge base advances to better inform regulatory decisions.

European Commission plans to ban food uses of BPA. We ask again: Where is FDA?

Maricel Maffini, consultant, and Tom Neltner, Senior Director, Safer Chemicals

What Happened?

On June 2, the European Commission, the executive body of the European Union (EU) responsible for proposing legislation and implementing decisions, announced it is preparing an initiative that “will impose a ban on the use of BPA [bisphenol A] in food contact materials (FCMs), including plastic and coated packaging.” It also said it would “address the use of other bisphenols in FCMs to avoid replacing BPA with other harmful substances.” The Commission’s proposal is based on the European Food Safety Authority’s (EFSA) scientific opinion that exposure to BPA is a “concern for human health.”

Why It Matters

In April, EFSA concluded that Europeans were exposed to levels of BPA from food that were 100 to 1,000 times greater than the estimated safe amount, and that this exposure could lead to an overactive immune system producing out-of-control inflammation. BPA was also associated with disrupting the endocrine system, harming reproduction, and reducing learning and memory. The immune system was most sensitive to BPA exposure. Recognizing these risks, the Commission moved quickly to protect Europeans’ public health by banning uses of BPA.

Our Take

Americans’ exposure to BPA from food is similar to that in Europe. Unfortunately, FDA doesn’t share the same sense of urgency to protect our families as the European Commission is demonstrating by its actions. While Europe is moving forward to ban the use of BPA in food contact materials, the FDA has failed to take action.

EDF and our allies submitted a food additive petition asking the agency to limit BPA exposure from food by revoking approvals for using BPA in adhesives and can coatings and to setting strict limits on using BPA in plastic that contacts food. FDA filed the petition on May 2, 2022 and has not made a final decision on it despite a 180-day statutory deadline. It is now more than 400 days overdue.

In January, FDA Commissioner Califf announced “a new and transformative vision for the FDA Human Food Programs” which includes a Deputy Commissioner for Human Foods with “decision-making authority over policy, strategy and regulatory program activities.” These are important steps, but a real measure is making timely decisions to protect American’s health by restricting the use of toxic chemicals such as BPA.

Next Steps

We will continue to press FDA to make a final decision on the petition, including potentially taking legal action for unreasonable delay in responding to our petition.

Representatives Call For FDA Public Hearing on Phthalates

By. Joanna Slaney, Senior Director, Federal Affairs, and Maricel Maffini, PhD, Consultant

What Happened?

On May 19, Reps. Katie Porter, Steve Cohen, Nanette Diaz Barragán, Earl Blumenauer, and Raúl Grijalva issued a letter [PDF, 300KB] to FDA Commissioner Robert Califf calling on FDA to “act expeditiously to protect the public from the health risks posed by phthalates in food and food packaging.”

They asked the FDA to hold a public hearing on ortho-phthalates (phthalates), chemicals associated with disruptions to the development of the male reproductive system and neurodevelopment, among other health effects.

Why It Matters

In 2021, Reps. Porter and Lieu led a letter with 12 colleagues urging FDA to take action on phthalates in food and cosmetics. That letter, in part, called on FDA to take action on a 2016 petition filed by EDF and allied environmental health organizations asking FDA to revoke its approval for all uses of phthalates in food packaging and processing equipment.

In May 2022, after the petitioners sued, FDA denied the petition. The petitioners formally objected to the decision and requested a public hearing pursuant to FDA’s regulations. The agency has not provided any timeline for acting on the objections.

Request for a Public Hearing

The Representatives stated in the letter submitted last month that  FDA’s decision denying the petition was flawed. “[W]e are deeply concerned about the denial, which was made without deciding whether the remaining approved uses of phthalates in food and food packaging are safe.” (Emphasis original)

They reminded Commissioner Califf of his recent statement that chemical safety is a “really, really important area for the future – for humankind, really – and where science is evolving rapidly,” urging FDA to hold a public hearing on two areas of concern:

  • The agency’s failure to evaluate the safety of phthalates as it was legally required to do before denying the 2016 petition. The letter stated, “failing to evaluate the safety of phthalates is an abdication of the FDA’s continuing obligation to oversee the safety of the food supply.”
  • FDA’s failure to address new toxicity information that raises significant questions about the safety of phthalates. Phthalates are associated with numerous health issues, including reproductive and developmental toxicity, endocrine disruption, immune toxicity, and epigenetic alterations. The letter stated, “the denial of the petition fails to acknowledge, let alone analyze, the dozens of peer-reviewed studies that underscore the toxicity of the phthalates that remain approved for food contact use.”

Next Steps

EDF and our allies will continue to press FDA to hold a public hearing on the safety of phthalates used in food packaging and processing equipment.

Mapping Lead: Ohio issues map of properties with known lead hazards

Tom Neltner, Senior Director, Safer Chemicals Initiative, and Roya Alkafaji, Manager, Healthy Communities

What Happened: The Ohio Department of Health published an interactive map showing almost 1,200 properties whose owners have refused to comply with an order to correct known lead-based paint hazards. As a result, the Department has declared these properties are unsafe to live in until the hazards have been remediated.

Why It Matters: The availability of address-specific information is important to engage residents, potential home buyers, and renters so they can make better informed decisions about protecting their families from harmful lead exposure. Ohio is the second state after New Jersey that we’re aware of to move beyond neighborhood-level mapping of lead risks to provide specific information at the address level.

Lead Pipe Replacement: EPA changes state shares of funding

Lindsay McCormick, Senior Manager, Safer Chemicals, Tom Neltner, Senior Director, Safer Chemicals and Roya Alkafaji, Manager, Healthy Communities

What Happened?

Earlier this month, EPA announced an updated formula it will use to allocate federal funds for lead service line (LSL) replacements. This new formula will be based on each state’s expected needs, as determined by a 2021 survey of state and water utility estimates.

Why It Matters

EPA’s distribution of the first of five years of the historic $15 billion dedicated to LSL replacement from the Infrastructure Improvement and Jobs Act (IIJA) was not necessarily going to states and communities that needed it most.

Many water utilities rely on the State Revolving Fund (SRF) program to build and maintain their drinking water infrastructure. EPA funds SRF programs each year and their previous formula to determine allocations was based on a 2015 survey of estimated drinking water infrastructure funding needs including LSL replacement – putting populous states like California at the top of the list. However, a 2016 article by the American Water Works Association (AWWA) showed LSLs are most heavily concentrated in the Midwest and Northeast, in states like Illinois, Ohio, Michigan, Missouri, New York, and New Jersey.

With EPA’s new formula, each state’s need, based on its estimated number of LSLs, will be used to distribute the next four years of IIJA funding for LSL replacement. This is a critical step to ensure that the system for distributing federal funds is functioning equitably and funds go to those communities with the greatest needs.

Projected Number of Lead Services Lines by State–2023

But wait…what’s going on in Florida and Texas?

When we dug into the details, there was one surprise in particular. Florida’s level of funding has increased a whopping 228%, based on a new estimate that the state has 1.2 million LSLs – more than any other state – and that about one in every six of its service lines is an LSL. Based on the age of infrastructure in the state, we think that this number is a gross overestimate. If we’re right, other states will get shorted on their share of LSL-replacement funding.

At first blush, data from Texas also caught our eye. The state reported almost 650,000 LSLs – up from 270,000 in the AWWA survey. But in contrast to Florida, this means Texas is claiming that only 5% of all its services lines are LSLs. Overall, Texas’ funding under the new formula will decrease by one-third.

What’s Next?

Starting this federal fiscal year (October 1, 2023), states will receive their new allocations of IIJA funding for LSL replacement. We’ll continue to monitor the funding flowing into each state for the critical task of getting the lead out, especially in communities that need it most. For states like Florida that may be in line for more than their fair share, we’ll be monitoring where those dollars are going.
