GoGreenNation News: Op-ed: After decades of disinformation, the US finally begins regulating PFAS chemicals
GoGreenNation News: Op-ed: After decades of disinformation, the US finally begins regulating PFAS chemicals

Earlier this month, the Environmental Protection Agency announced it would regulate two forms of PFAS contamination under Superfund laws reserved for “the nation’s worst hazardous waste sites.”EPA Administrator Michael Regan said the action will ensure that “polluters pay for the costs to clean up pollution threatening the health of communities.”That was an encore to the Food and Drug Administration announcing in February that companies will phase out food packaging with PFAS wrappings and the mid-April announcement by Regan that the EPA was establishing the first-ever federal limits on PFAS in drinking water. At that time, he declared, “We are one huge step closer to finally shutting off the tap on forever chemicals once and for all.”One can forever hope the tap will be eventually shut, since it took seemingly forever for the nation to begin to crack down on this class of per-and polyfluoroalkyl synthetic chemicals. The chemical bonds of PFAS, among the strongest ever created, resulted in an incredible ability to resist heat, moisture, grease and stains. PFAS chemicals seemed like miracle substances in the 20th-century quest for convenience. They became ubiquitous in household furnishings, cookware, cosmetics, and fast-food packaging, and a key component of many firefighting foams. “We are one huge step closer to finally shutting off the tap on forever chemicals once and for all.” - EPA Administrator Michael Regan The bonds are so indestructible they would impress Superman. They don’t break down in the environment for thousands of years, hence the “forever” nickname. Unfortunately for humans, the same properties represent Kryptonite. Today, the group of chemicals known as PFAS is the source of one of the greatest contaminations of drinking water in the nation’s history. Flowing from industrial sites, landfills, military bases, airports, and wastewater treatment discharges, PFAS chemicals, according to the United States Geological Survey, are detectable in nearly half our tap water. Other studies suggest that a majority of the U.S. population drinks water containing PFAS chemicals—as many as 200 million people, according to a 2020 peer-reviewed study conducted by the Environmental Working Group. PFAS chemicals are everywhereNo one escapes PFAS chemicals. They make it into the kitchen or onto the dining room table in the form of non-stick cookware, microwave popcorn bags, fast-food burger wrappers, candy wrappers, beverage cups, take-out containers, pastry bags, French-fry and pizza boxes. They reside throughout homes in carpeting, upholstery, paints, and solvents.They are draped on our bodies in “moisture-wicking” gym tights, hiking gear, yoga pants, sports bras, and rain and winter jackets. They are on our feet in waterproof shoes and boots. Children have PFAS in baby bedding and school uniforms. Athletes of all ages play on PFAS on artificial turf. PFAS chemicals are on our skin and gums through eye, lip, face cosmetics, and dental floss. Firefighters have it in their protective clothing.As a result, nearly everyone in the United States has detectable levels of PFAS in their bodies. There is no known safe level of human exposure to these chemicals. They are linked to multiple cancers, decreased fertility in women, developmental delays in children, high cholesterol, and damage to the cardiovascular and immune systems. A 2022 study by researchers from Harvard Medical School and Sichuan University in China estimated that exposure to one form of PFAS (PFOS, for perfluorooctane sulfonic acid), may have played a role in the deaths of more than 6 million people in the United States between 1999 and 2018.As sweeping as PFAS contamination is, exposures in the United States are also marked by clear patterns of environmental injustice and a betrayal to military families. An analysis by the Union of Concerned Scientists found that people of color and low-income people were more likely to live near non-military sources of PFAS contamination than wealthier, white people.Another study by UCS found that 118 of 131 military bases had PFAS contamination concentrations at least 10 times higher than federal risk levels. A federal study last year found a higher risk of testicular cancer for Air Force servicemen engaged in firefighting with PFAS foams.Tobacco-like disinformationIn the end, the whole nation was betrayed, in a manner straight out of the tobacco disinformation playbook. Behind the image of convenience, manufacturers long knew that PFAS chemicals were toxic. Internal documents uncovered over the years show how DuPont and 3M, the two biggest legacy makers of PFAS, knew back in the 1960s that the compounds built up in blood and enlarged the livers of laboratory animals. By 1970, a DuPont document referring to a PFAS chemical under its famed “Teflon” trademark said that it “is highly toxic when inhaled and moderately toxic when injected.”By the late 1970s, DuPont was discovering that PFAS chemicals were affecting the liver of workers and that plant employees were having myocardial infarctions at levels “somewhat higher than expected.” But that did not stop the industry from downplaying the risk to workers.One internal 3M document in 1980 claimed that PFAS chemicals have “a lower toxicity like table salt.” Yet, a study last year of documents by researchers at the University of California San Francisco and the University of Colorado found that DuPont, internally tracking the outcome of worker pregnancies in 1980 and 1981, recorded two cases of birth defects in infants. Yet, in 1981, in what the researchers determined was a “joint” communication to employees of DuPont and 3M, the companies claimed: “We know of no evidence of birth defects” at DuPont and were “not knowledgeable about the pregnancy outcome” of employees at 3M who were exposed to PFAS. The same suppression and disinformation kept government regulators at bay for decades. The San Francisco and Colorado researchers found internal DuPont documents from 1961 to 1994 showing toxicity in animal and occupational studies that were never reported to the EPA under the Toxic Substances Control Act. As one example, DuPont, according to a 2022 feature by Politico’s Energy and Environment News, successfully negotiated in the 1960s with the Food and Drug Administration to keep lower levels of PFAS-laden food wrapping and containers on the market despite evidence of enlarged livers in laboratory rats.A patchwork responseEventually, the deception and lies exploded in the face of the companies, as independent scientists found more and more dire connections to PFAS in drinking water and human health and lawsuits piled up in the courts. Last year, 3M agreed to a settlement of between $10.5 billion and $12.5 billion for PFAS contamination in water systems around the nation. DuPont and other companies agreed to another $1.2 billion in settlements. That’s not nothing, but it is a relatively small price to pay for two industrial behemoths that have been among the Fortune 500 every year since 1955.In the last two decades, the continuing science on PFAS chemicals and growing public concern has led to a patchwork of individual apparel and food companies to say they will stop using PFAS in clothes and wrapping. Some states have enacted their own drinking water limits and are moving forward with legislation to restrict or ban products containing PFAS. In 2006, the EPA began a voluntary program in which the leading PFAS manufacturers in the United States agreed to stop manufacturing PFOA, one of the most concerning forms of PFAS.But companies had a leisurely decade to meet commitments. Even as companies negotiated, a DuPont document assumed coziness with the EPA. “We need the EPA to quickly (like first thing tomorrow) say the following: Consumer products sold under the Teflon brand are safe. . .there are no human health effects to be caused by PFOA [a chemical in the PFAS family].”Two years ago, 3M announced it will end the manufacture of PFAS chemicals and discontinue their application across its portfolio by the end of next year. But the company did so with an insulting straight face, saying on its products are “safe and effective for their intended uses in everyday life.”EPA action finally, but more is neededThe nation can no longer accept the overall patchwork or industry weaning itself off PFAS at its own pace. The EPA currently plans to issue drinking water limits for six forms of PFAS and place two forms under Superfund jurisdiction. The Superfund designation gives the government its strongest powers to enforce cleanups that would be paid for by polluters instead of taxpayers.”But there are 15,000 PFAS compounds, according to the National Institute of Environmental Health Sciences. There is nothing to stop companies from trying to play around with other compounds that could also prove harmful. Cleaning up the PFAS chemicals that have already been allowed will take billions of dollars and water utilities around the country are already screaming, with some justification, that the federal government needs to provide more money than it is offering. And even the Superfund designation does not actually ban their use.It would be better if the United States were to follow the lead of the European Union, which is now considering a ban or major restrictions on the whole class of chemicals, fearing that “without taking action, their concentrations will continue to increase, and their toxic and polluting effects will be difficult to reverse.”The effects are scary to quantify. Regan said in his drinking water announcement that the new rules would improve water quality for 100 million people and “prevent thousands of deaths and reduce tens of thousands of serious illnesses across the country.” A draft EPA economic analysis last year predicted that tight standards could save more than 7,300 lives alone from bladder cancer, kidney cancer and cardiovascular diseases, and avoid another 27,000 non-fatal cases of those diseases.That makes it high time that the federal government borrow from DuPont’s arrogant assumption that it could push around the EPA. We need the EPA to quickly (like first thing tomorrow) say the following: Consumer products with PFAS are not safe and are causing unacceptable environmental consequences. We are shutting off the tap on ALL of them.”

GoGreenNation News: Op-ed: An open letter to the Food and Drug Administration Commissioner
GoGreenNation News: Op-ed: An open letter to the Food and Drug Administration Commissioner

The U.S. Food and Drug Administration (FDA) is going through a major reorganization to improve efficiency and protect public health. A recent hearing in front of the House Committee on Oversight and Accountability concluded that the agency stumbles from crisis to crisis, including drug shortages, tainted food and illicit tobacco scandals in recent years.Although crises such as the contamination of baby food with heavy metals like lead and mercury gain public attention, the scientific approach used by FDA to regulate chemical additives in food is much more opaque. While it largely flies under the public radar, the agency’s neglect to update its testing to reflect modern science and modern food chemical hazards is a decades-long crisis that impacts all of our health. The agency has fallen behind other nations’ testing and regulations and is not even following laws put in place nearly 70 years ago to keep us safe. We are calling on FDA Commissioner, Dr. Robert M Califf, to use the agency reorganization as an opportunity to overhaul its approach to chemicals in our food and put public health at the center of its work. How does the FDA evaluate the safety of food additives and contaminants?Recently, the FDA published a consumer update entitled, “Is food safe if it has chemicals?” In it, the agency says that it’s the amount of a chemical in food that determines its risk to our health. They use sodium as an example. While it largely flies under the public radar, the agency’s neglect to update its testing to reflect modern science and modern food chemical hazards is a decades-long crisis that impacts all of our health.We need sodium to live, but too much sodium can be bad, so they publish guidance on the safe level of sodium to be consumed each day. But many of the chemicals that wind up in our food are not required for us to live, such as bisphenols like BPA, phthalates or the group of chemicals known as PFAS or “forever chemicals”. In fact, many of these are not required for food production, but leach into food from packaging and equipment. FDA noncompliance The FDA discusses how they intentionally determine an “acceptable daily intake” for a chemical that includes a safety margin. The idea is that this safety margin is so conservative that it will always protect public health.However, we know chemicals in the diet can come from a variety of food sources and that different chemicals can have the same adverse effect. This is so well-known that the 1958 amendment to the Food, Drugs and Cosmetic Act of 1938 required that FDA evaluate the “cumulative effect of the substance in the diet, taking into account any chemically or pharmacologically related substance or substances in such diet.”Sixty-six years later and the FDA has never complied with this part of the law. A good example: its guidance for lead in baby food, in which they set the suggested (not required) limit to be 20 parts per billion. However, there is no safe blood level of lead, which hurts children’s brains, resulting in lower IQ and behavioral problems among other harmful effects.It’s not just lead: recently, the Dutch risk assessment agency reported that the combined exposure to lead, methyl-mercury, arsenic, polychlorinated biphenyls or PCBs, polybrominated diphenyl ethers or PBDEs and fluoride were much more potent at reducing children’s IQ than any one of these chemicals alone.Similarly, the FDA continues to defend its ruling that current levels of BPA in food are safe despite the decision by the European Food Safety Authority, the EFSA, to reduce the “safe level” of BPA by 20,000 fold. The FDA defends its position by focusing on BPA as if it is the only chemical in foods that act like the female hormone estrogen. In contrast, it is well known that plastic food packaging contains a number of estrogen-like chemicals, like other bisphenols and phthalates, that can leach into foods.The failure of the FDA to comply with the 1958 amendment to food safety law is not just a violation of the law but presents a significant risk to American consumers. A citizen’s petition was filed with the agency in 2020 to attempt to cajole it into compliance. The FDA has never responded.Considering this, we wrote to Commissioner Califf to address this serious shortcoming of FDA’s Human Food Program. The Commissioner has not responded. The letter is re-printed below.March 11, 2024Robert M Califf, M.D., CommissionerUnited States Food and Drug AdministrationCc: James Jones, Ph.D., Deputy CommissionerFDA Human Foods Program Dear Commissioner Califf, We read with great interest your OpEd with Dr. Warraigh entitled, “Four steps toward meeting the challenge of chronic disease” (The Hill, 02/15/24). This is a particularly important issue considering that the United States is below average compared to peer economies in 9 health domains, including adverse birth outcomes, obesity and diabetes, heart disease and chronic lung disease. And this, as you point out, is despite US taxpayers spending nearly 18% of our GDP on healthcare.However, we are concerned that there was no mention of food-borne chemicals that are either added to food intentionally or that migrate into food from packaging or processing. The recent analysis by the New York Times of the failure of the food safety system that resulted in hundreds of children being poisoned by lead in applesauce illustrates in part how our system of food safety needs to be improved.More important to the issue of chronic disease is that of chemicals in the food supply that are being evaluated for safety in a one-by-one approach, rather than considering the “cumulative effect of the substance in the diet, taking into account any chemically or pharmacologically related substance or substances in such diet” as required by the 1958 amendment to the Food, Drugs, and Cosmetic Act of 1938. Recent studies demonstrate that the cumulative effect of Americans’ exposure to endocrine-disrupting chemicals in the food supply contributes to harmful health impacts including chronic disease, increasing healthcare costs in the hundreds of billions of dollars annually, as well as affecting quality of life. Importantly, the scientific evidence is sufficient to conclude that the cumulative effects of biologically related substances in the food supply contributes to chronic diseases such as obesity or diabetes. We urge you to consider it as a critical “fifth step” in meeting the challenge of chronic disease in the United States, one that the agency is already mandated to conduct.For example, a recent study contributed by the Dutch risk assessment agency (RIVM) in collaboration with Professor Andreas Kortenkamp, a world-leader in the analysis of cumulative risk, demonstrated that in 9 countries in the EU, their populations exceeded combined tolerable levels of exposure to a mixture of chemicals at median exposure levels. Thus, the traditional way of identifying a “Tolerable Daily Intake” using a chemical-by-chemical basis is clearly underestimating the cumulative risk of chemicals with similar structure or observable effects.Despite the 1958 amendment requiring the FDA to evaluate cumulative effects of chemically related and biologically related substances in the diet, the agency has never performed this analysis for any chemical additives. Moreover, the FDA has not responded to citizen petitions or Congressional queries asking for the FDA to comply with the spirit and letter of this law. It simply is past time that the Agency stop ignoring the law and incorporate cumulative risk assessments in their regulatory approaches.We ask that FDA form a committee of its Science Board including external experts to guide the agency as it addresses this shortcoming in its current safety assessment methods. When it passed the 1958 law, Congress recognized that chemicals, even ones that are not chemically related, may impact organs such as the thyroid and systems such as the cardiovascular with different mechanisms of action but cumulatively have a greater negative effect on the health of the American people.Finally, we are happy to meet with you to provide further information and insight or to contribute to the changes that need to be made in any way that we can.Sincerely,Linda S.

GoGreenNation News: EPA lists 2 common "forever chemicals" as Superfund hazardous substances
GoGreenNation News: EPA lists 2 common "forever chemicals" as Superfund hazardous substances

Two toxic, widely used "forever chemicals" are now classified as hazardous substances under a new rule that the Biden administration finalized on Friday. Why it matters: The rule, under the federal Superfund law, will require companies to report any leaks of the two chemicals and will allow the Environmental Protection Agency (EPA) to hold polluters accountable by forcing them to clean up their contamination.The rule builds on other recent actions that the Biden administration has taken to curb per- and polyfluoroalkyl substances (PFAS) pollution.The EPA recently announced the first-ever drinking water standards targeting some of the synthetic compounds.What they're saying: "Designating these chemicals under our Superfund authority will allow EPA to address more contaminated sites, take earlier action, and expedite cleanups, all while ensuring polluters pay for the costs to clean up pollution threatening the health of communities," EPA Administrator Michael Regan said in a statement on Friday.The other side: The American Chemical Council, which represents major PFAS producers, in a statement on Friday said it "strongly" opposes the EPA's action.It claimed the federal action was based on "severely flawed" science and was an "unworkable means to achieve remediation for these chemicals."Threat level: PFAS are dubbed "forever chemicals" because they resist degradation by repelling oil and water and withstanding high temperatures.Used extensively in nonstick, water- and oil-repellent and fire-resistant industrial and consumer products, PFAS can bioaccumulate in people, livestock, wildlife and fish if they enter the environment and water sources.The health effects of the chemicals are still being studied, but exposure to certain levels of PFAS has been linked to adverse health effects in humans and animals, including increased risk of kidney or testicular cancer.Driving the news: The EPA's new rule only applies to two specific types of PFAS — PFOA and PFOS — but there are over 12,000 different types of PFAS. While PFOA and PFOS have been the most widely used PFAS throughout history, they are no longer produced in the U.S., as chemical manufacturers and other companies have turned to other PFAS in recent years.However, PFOA and PFOS are still produced internationally and can be imported into the U.S. in consumer goods.Because there are so many PFAS, multiple Environmental groups have called on the EPA to regulate the substances as a class instead of taking action against individual chemicals.Zoom out: PFAS contamination is extensive throughout the U.S., with federal studies suggesting that the chemicals can be detected in almost half of the nation's tap water.Private studies have also shown widespread PFAS contamination in water systems, while other research has indicated that people living in Hispanic and Black communities are disproportionately exposed to PFAS. Since 1999, Centers for Disease Control and Prevention scientists have consistently detected multiple PFAS in blood serum samples from nearly all people who take part in its annual National Health and Nutrition Examination Survey.The big picture: In recent years, major chemical producers have agreed to pay billions to settle claims from U.S. water providers over their production and handling of PFAS.Other companies, like fast food corporations, have begun making promises to phase out the use of PFAS in their products.Several research teams in the U.S. and around the world are searching for new ways to destroy forever chemicals and filter them from water systems.Go deeper: EPA unveils new rules to curb toxic emissions at U.S. chemical plantsEditor's note: This story was updated with comment from The American Chemical Council.

GoGreenNation News: Q&A: Award-winning scientist Anne Starling on the latest PFAS research— and where she finds hope
GoGreenNation News: Q&A: Award-winning scientist Anne Starling on the latest PFAS research— and where she finds hope

EHN senior news editor Brian Bienkowski saw down with Dr. Anne Starling, winner of the 2023 Lou Guillette Jr Outstanding Young Investigator Award, to discuss her work on PFAS and other toxics, how this has shaped her consumer habits, and where she finds hope. The Lou Guillette Jr. Outstanding Young Investigator Award is an annual award given to an early career scientist who studies endocrine-disrupting chemicals — compounds like BPA and phthalates that alter the proper functioning of our hormones. Starling, an Assistant Professor in the Department of Epidemiology at the Gillings School of Global Public Health at the University of North Carolina, Chapel Hill and an adjunct Assistant Professor in the Department of Epidemiology at the Colorado School of Public Health, studies how chemical exposures, such as PFAS in drinking water, may increase the risk of chronic disease. The award is conducted by HEEDS — a program within Environmental Health Sciences, which publishes EHN.org. We talked to Starling about the award and her work. The interview has been lightly edited for brevity and clarity. First off, congrats on the 2023 Lou Guillette Jr. Outstanding Young Investigator Award. Where in your academic and research journey did you start investigating endocrine-disrupting chemicals?Thank you. I’m very honored by this award because I admire the work of HEEDS and also what I know of Dr. Guillette’s legacy as a scientist and a mentor. I’ve always been interested in environmental health, in how humans are influencing the natural environment, and how our own health may be affected by the way we construct and modify our environment. I began studying exposure to endocrine-disrupting chemicals when I was a graduate student in epidemiology at UNC Chapel Hill. I was fortunate to work with mentors both at UNC and at the National Institute of Environmental Health Sciences (NIEHS). At NIEHS, I worked with Dr. Jane Hoppin on the question of how exposure to agricultural pesticides may increase diabetes risk. Later, for my dissertation project, I worked with Dr. Stephanie Engel at UNC and Dr. Matthew Longnecker at NIEHS to investigate how exposure to certain persistent chemicals (per- and polyfluoroalkyl substances, or PFAS) during pregnancy can affect the health of the pregnant person and the outcome of the pregnancy.What is something you’ve uncovered in your time investigating these harmful chemicals that most people would find surprising?Many people that I talk to assume that chemical products that are widely used in the U.S. have gone through comprehensive safety testing, similar to what is required for prescription drugs and other medical treatments. But this is simply not the case. In our regulatory environment, the burden is on the regulators to demonstrate harm from exposure to chemicals, rather than a more precautionary approach. And it may surprise many people to know just how long it takes to accumulate enough scientific evidence to change policy. This is not necessarily due to any kind of conspiracy or political influence, but simply because science is slow, meticulous, and deliberate. It takes years to be confident that we have the right answers.Some of your research has focused on PFAS in drinking water and its impact on developing fetuses. What have you found?Yes, I’ve studied the effects of prenatal exposure to PFAS for several years now.There are now many studies that have reported that pregnant people with higher PFAS in their blood have babies that have, on average, somewhat lower weight at birth. This is concerning because we know that babies with low birth weight have a number of health challenges that may last throughout their lives. And even though the effects of PFAS exposure on birth weight may be small at the individual level, the impact could be large from a public health perspective because nearly everyone in the U.S. is exposed to these chemicals. My work has examined whether PFAS exposures at critical periods of development are linked with different patterns of child growth, that could potentially put them at greater risk of obesity, diabetes, and other chronic diseases. We’ve seen some evidence that exposures before birth may influence child growth, body weight and body composition (the amount of fat mass compared to lean body mass) through at least the age of school entry, and maybe longer.When we think of pollution exposure, we often think of acute impacts, but that’s not always the case. What have you found when it comes to endocrine-disrupting chemicals’ ability to create long-lasting impacts to our health?In general, we know a lot more about the acute effects of high doses of toxic chemicals than we know about the chronic or long-term effects of the low doses received daily by the general population. It’s challenging to study changes in people’s health related to exposures over many years, and that’s why epidemiology as a field is so interesting to me – we spend a lot of time thinking a bout how to overcome the challenges of observational research to draw valid and useful conclusions. When you don’t have a randomized controlled trial -which we almost never do in environmental health, for obvious ethical reasons –you have to be very strategic and rigorous in your study design to learn whether a certain exposure is actually causing harm.Has doing this research changed how you act as a consumer? If it has, how so?I think so. I am more wary of the chemical products that I bring into my home. I’m definitely a label-reader! But a major lesson that I have learned through this work is that we are not empowered as consumers to be able to avoid harmful chemicals in our daily lives. There are no ingredient labels on most of the products that we encounter every day, such as food packaging, clothing, furniture, and even the building materials and paint in our homes. It’s impossible for an individual to make well-informed decisions about all of these products. So rather than making recommendations about consumer choices, I advocate for policy changes to make sure that products that are known to be unsafe are not sold to consumers.What research are you working on now that excites you?In terms of impact, I’m excited to be contributing to a large, multi-site study of the health effects of PFAS exposure through drinking water, led by the Agency for Toxic Substances and Disease Registry. The study enrolled people from seven communities around the country, who all experienced high levels of PFAS in their drinking water at some point. I worked in one of these communities in Colorado for several years, and I have seen the level of worry and frustration that these contamination events can cause. It’s gratifying to be able to tell people who participated in these studies that we are now on the verge of having enforceable, national regulations on the maximum allowable amount of specific PFAS in drinking water. Scientifically, I’m also excited to be investigating other sensitive periods of exposure during the life course, beyond prenatal development. For example, puberty, pregnancy and menopause are dramatic periods of hormonal and physiological change, and they may also be critical windows during which exposure to endocrine-disrupting chemicals can cause lasting harm.We are consistently hearing about the chemical exposures in our lives and it can be daunting. What gives you hope when it comes to these exposures and our health?We are more educated than ever before about the trade-offs that we face in our industrial society. And we do make progress. Just think about how much healthier our children’s lives may be because they aren’t exposed to as much tobacco smoke or lead compared to previous generations. The science is moving at a remarkable pace, and we have to commit to adapting and changing as we learn more.

GoGreenNation News: What will the EPA’s new regulations for “forever chemicals” in drinking water mean for Pennsylvania?
GoGreenNation News: What will the EPA’s new regulations for “forever chemicals” in drinking water mean for Pennsylvania?

PITTSBURGH — Last month the U.S. Environmental Protection Agency (EPA) announced the first federal regulations for “forever chemicals” in drinking water. The chemicals, known as per- and polyfluoroalkyl substances or PFAS, are linked to kidney and testicular cancer, liver and thyroid problems, reproductive problems, pregnancy-induced high blood pressure, low birthweight and increased risk of birth defects, among other health effects. There are nearly 15,000 different PFAS and evidence of the chemicals has been found in everything from carpets and cookware to food wrappers, makeup and bandaids. PFAS don’t break down naturally and have been detected in drinking water at more than 5,000 sites in all 50 states. The new regulations, among the most protective health limits on PFAS in drinking water in the world, will go into effect on June 25 and set limits for six common PFAS — PFOA, PFOS, PFHxS, PFNA, PFBS and GenX. Many researchers who study these chemicals have called on regulators to restrict these chemicals as a class rather than individually. But because the chemicals build up in our bodies over time, any reduction in exposure is likely to be beneficial for health. “This is the first time the EPA has issued a rule on water contaminants in 28 years. So this is significant,” Michelle Naccarati-Chapkis, executive director of Women for a Healthy Environment, a nonprofit environmental health advocacy group based in western Pennsylvania, told EHN. Eleven states, including Pennsylvania, Maine, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Rhode Island, Vermont, Washington and Wisconsin have already adopted their own limits on PFAS in drinking water. The EPA’s new limits are stricter than any existing limits, so states are preparing to meet the new EPA standards. “PFAS exposures are toxic even at low concentrations,” Naccarati-Chapkis said. “We didn’t think Pennsylvania’s state regulations went far enough, so we’re glad these new federal rules will better protect residents across the Commonwealth.” What are the new limits and how will they protect our health?The EPA’s new PFAS limits are 4 parts per trillion (ppt) for PFOA and PFOS and 10 ppt for GenX, PFNA and PFHxS, all of which are newer PFAS that have been less extensively studied than PFOA and PFOS. The regulations also create a “hazard index” to address combined risks from mixtures of chemicals. For PFNA, GenX, PFHxS and PFBS, water system operators will determine if the combined levels of two or more in drinking water pose a potential risk and require action. The regulations also consider the levels of PFAS that can be detected by laboratories and the cost and feasibility of removing them. The EPA set “Maximum Contaminant Level Goals” for some PFAS, which represent the limit at which the agency has determined that no adverse health effects would occur. Whenever the EPA has identified a cancer risk associated with a pollutant, the Maximum Contaminant Level Goal is set to zero, which the agency has applied to PFOA and PFOS. While the Maximum Contaminant Levels of 4 ppt for PFOA and PFOS and 10 ppt for PFHxS, PFNA, and GenX are enforceable, the Maximum Contaminant Level Goals are aspirational. “Setting those goals to zero is an acknowledgement that there’s basically no safe level of exposure to these chemicals,” Carla Ng, an associate professor and PFAS researcher at the University of Pittsburgh, told EHN. The Biden administration expects the new regulations to “protect 100 million people from PFAS exposure, prevent tens of thousands of serious illnesses and save lives.” Additionally, the EPA recently classified PFOA and PFOS, two of the most common PFAS, as “hazardous substances” under the federal Superfund act, which gives the EPA the authority to clean up PFAS contamination and to recover the cost of these cleanups from polluters. “I think these two pieces are one two-punch,” Ng said. “With both, now we’ll have a way to clean up not only water, but also other mediums like soil. That’s important because PFAS exposure also happens through things like indoor air and contaminated food, and this will allow us to start addressing those exposures too.”What will this mean for Pennsylvania?One in three Pennsylvania drinking water systems had detectable levels of PFAS as of 2021. Additionally, PFAS have been detected in 76% of sampled rivers and streams throughout the state, many of which are used for drinking water.In January 2023, six years after initially pledging to regulate the chemicals, the Pennsylvania Department of Environmental Protection passed limits of 14 ppt for PFOA and 18 ppt PFOS in drinking water. Now, those limits must be tightened. “Pennsylvania is already working to revise its regulations to align with the federal rulemaking in places where the state rule is less stringent,” PA DEP spokesperson Neil Shader told EHN. Pennsylvania’s regulations need to be updated within two years of the start date for the new federal rules. The agency plans to help water authorities address any challenges and secure funding.“DEP will take every step to ensure water authorities in the Commonwealth can meet state and federal limits for PFAS – including increased training and to help local operators understand the new federal rule,” Shader said. “Additionally, [the Pennsylvania Infrastructure Investment Authority] has been able to fund 100% of all requests for the construction and installation of treatment facilities to date and has the financial capacity to address any additional requests for the foreseeable future.”The EPA also offers assistance programs for water authorities that need help implementing monitoring and treatment of contaminants like PFAS. The Biden’s administration dedicated $9 billion in funding to address PFAS and other emerging contaminants in drinking water through the $1 trillion infrastructure legislation that passed IN 2021, commonly known as theBipartisan Infrastructure Law. “Pennsylvania is already working to revise its regulations to align with the federal rulemaking in places where the state rule is less stringent." - Neil Shader, PA DEP spokesperson The new regulations do not apply to the approximately 2.5 million Pennsylvania residents whose water comes from private wells.“DEP recommends private residents who choose to test their water use a state-certified laboratory using EPA-approved testing methods,” Shader said, noting that the agency offers a list of accredited laboratories online.Ng said more resources are needed to help private well owners. “That has always been a big blind spot in Pennsylvania,” she said. “There’s very little protection for people with private wells, and we really need funds to help them do testing and treatment for PFAS and other contaminants as well.”For some water authorities, including the Pittsburgh Water and Sewer Authority, which provides drinking water to more than 500,000 people, the new rules won’t require many changes.“We always try to be proactive about looking at emerging contaminants,” Frank Sidari, chief environmental compliance and ethics officer at the Pittsburgh Sewer and Water Authority (PWSA), told EHN. “We’ve been monitoring for PFAS since 2014, so it won’t be too difficult for us to prepare for the new federal regulations.”So far, Sidari said, the municipal authority’s monitoring hasn’t detected levels of PFAS high enough to prompt removal of the contaminants. “We always try to be proactive about looking at emerging contaminants. We’ve been monitoring for PFAS since 2014, so it won’t be too difficult for us to prepare for the new federal regulations.” - Frank Sidari, Pittsburgh Sewer and Water AuthorityAt some smaller water authorities, the new regulations will require a bigger lift. The Wilkinsburg-Penn Joint Water Authority, which serves around 40,000 people in western Pennsylvania, began some voluntary monitoring for a list of 29 PFAS in both drinking water and source water in 2023 in anticipation of new EPA monitoring requirements, but the process is still new.“This is an extremely complex group of contaminants,” Lou Ammon, manager of purification at the Wilkinsburg-Penn Joint Water Authority, told EHN. “We have not received any resources to date and do not expect to receive any resources for our continued enhanced monitoring.”While the state’s environmental agency said resources are available for water authorities that reach out to and request help removing PFAS, both Ammon and Sidari said they hadn’t received any outreach from state regulators advertising or offering resources to help with PFAS monitoring or removal.To date, Ammon said, the Wilkinsburg-Penn Joint Water Authority hasn’t detected PFAS high enough to prompt new treatments, but “if we ever have to treat/remove PFAS from our water during treatment, I have not been informed of what resources we should expect to receive at that time.”“What I really think we need are regulations and remediation funding sources from businesses and corporations that have profited directly from the manufacture and use of these compounds,” Ammon said.As of April 2024, attorney generals in 30 states, including Pennsylvania, have initiated lawsuits against manufacturers of PFAS for contaminating water supplies, according to Safer States, a national coalition of environmental health organizations. “What I really think we need are regulations and remediation funding sources from businesses and corporations that have profited directly from the manufacture and use of these compounds.” - Lou Ammon, Wilkinsburg-Penn Joint Water AuthorityAmmon also called for regulation of PFAS in consumer products. Some states have begun banning PFAS in consumer products, but Pennsylvania has not.“Every day that these direct consumer contamination sources are unregulated is a day that these compounds can be affecting the public’s health or contaminating source water,” Ammon said, “[and] that will ultimately need to be treated and paid for by water treatment plant rate-payers and in federal/state tax dollars, paid by the public.”

GoGreenNation News: Op-ed: Is plastic the biggest climate threat?

As people from around the world are gathering in New York for the UN-sponsored Climate Week, it is past time the world focused on the threats to climate from plastics.For decades the fossil fuel industry has rightly been a target for climate action. It was major news last year when the UN climate change conference for the first time in decades agreed on calling for a transition away from fossil fuels. But many missed the loophole in that statement: fossil-fuel producing countries only agreed to this language with the caveat that the transition would be away from fossil fuels “in energy systems.” The agreement says nothing about moving away from fossil fuels for plastics or chemicals.With the rapid rise of electric cars and other electrification technologies, the oil and gas industry is looking to plastics and the chemicals that go into plastics as their primary new markets. Many people don’t know that plastics are made from oil and gas mixed with chemicals, mostly petrochemicals that are also produced from fossil fuels. Plastics are the industry’s golden goose and they are gearing up for a massive expansion in production. A recent report noted that Chevron, Shell, and oil-producing nations are responding to predictions about the decline of their industry with large investments in petrochemical and plastic production. They believe their future is plastics.But scientists are warning that more plastics means more threats to the climate. A study from the U.S. government’s Lawrence Berkeley National Laboratory earlier this year found that greenhouse gas emissions from plastics could triple by mid-century, accounting for 20% of the remaining carbon budget before planetary disruptions become unbearable. Other researchers have found that pollution from plastics and chemicals has already exceeded the “planetary boundaries” for sustaining life on Earth. Some say more recycling will fix the plastics problem, but plastic recycling has remained at less than 10% globally for decades and because plastics are made with toxic chemicals, recycling simply spreads these chemicals to new products.Despite the climate agreement’s call to “transition away” from fossil fuels, the industry is aiming to triple plastics production by 2050. This means increasing fossil fuels extraction and petrochemical production, with the attendant and potentially disastrous climate, health, and environmental consequences. In the Arctic, we see the consequences of the fossil fuels, petrochemicals, and plastics industry daily. Our recent report noted that the Arctic is a “hemispheric sink” where plastic pollution from around the world accumulates, leaching toxic chemicals that threaten the climate, food security, our health, and the environment. The report demonstrates how chemicals, plastics, and climate change are interrelated and have combined to poison lands, waters, and traditional foods of Arctic Indigenous Peoples, with ongoing health effects that threaten their cultures and communities.In Indonesia and around the Global South, the industry is promoting a buildup of fossil fuels, plastics, and chemicals production as well as toxic plastic waste disposal technologies, like incineration and chemical recycling, that create significant greenhouse gases and toxic emissions. Already, evidence shows that unmanageable plastic waste around the world threatens the climate and causes toxic contamination of the air, water, and food chain, especially for people living close to waste dumps, incinerators, and plastic recycling facilities.Increasing production of plastics derived from fossil fuels will not only threaten the climate but also our health. A recent study found that more than 4,200 chemicals used in plastics are known to be “highly hazardous” to health or the environment, and thousands more plastic chemicals have never been tested for safety. Chemicals common in plastics are linked to cancer, impacts on brain development and behavior, infertility, low sperm count, reduced testosterone and estrogen levels, impacts on neurodevelopment and IQ-performance, immune system damage, and endocrine disruption, among other health concerns.While the U.N. Climate Week is in the spotlight, the world is also in the process of negotiating another significant climate pact, the U.N. Plastics Treaty, a global agreement aimed at addressing the plastics crisis. Given the stakes, the Treaty should be considered a climate and health agreement that addresses the climate and toxic threats throughout the life cycle of plastics. We must understand plastics as a mixture of carbon (fossil fuels) and chemicals and address the climate and health consequences when fossil fuels are extracted to make plastics, when petrochemicals for plastics are produced, when plastic production and disposal threatens nearby communities, and when plastic products pose risks to consumers.In short, a Plastics Treaty for the climate and health must address overproduction of plastics and head off the petrochemical and plastic industry’s planned expansion. To miss this opportunity to rein in these polluting, toxic industries could have disastrous consequences for generations to come.
