Former chemical industry official Beck, now at Trump White House, again interferes to weaken EPA action on dangerous chemicals: This time it’s PFAS

It was only in February that Reveal News’ Elizabeth Shogren exposed the Trump White House’s role in dramatically weakening the Environmental Protection Agency’s (EPA) draft risk evaluation for the solvent trichloroethylene (TCE), which is linked to fetal heart defects at low doses.  The White House’s 11th-hour intervention, led by former chemical industry official Dr. Nancy Beck, forced EPA to rely on a different health effect that would allow 500 times greater exposures to the ubiquitous toxic chemical.

There was every reason to expect this episode was not a one-off, given Beck’s other actions both while at EPA and once arriving at the White House.  Sure enough, last week Ellen Knickmeyer of the Associated Press exposed another such incident, this time involving a group of chemicals collectively known as “perfluoroalkyl and polyfluoroalkyl substances” or PFAS that are showing up as environmental contaminants all over the country.[pullquote]Beck’s first order of business was to compel her former colleagues at EPA to submit the proposed PFAS rule for White House review, which neither the Obama administration nor the Trump administration up to that point had deemed necessary.[/pullquote]

Knickmeyer reported on documents obtained by Senator Tom Carper of Delaware, ranking member of the Senate’s Environment and Public Works Committee, that detail Beck’s largely successful effort to scale back a rule EPA first proposed in 2015.  Called a Significant New Use Rule, or SNUR, it would require companies seeking to import products containing certain PFAS to notify EPA in advance, thereby allowing EPA to determine whether to allow the import and impose needed restrictions.  Sen. Carper made the documents public via a letter he sent to EPA Administrator Andrew Wheeler calling on EPA to finalize the original rule instead of the watered-down re-proposed rule EPA released for public comment in February.  Read More »

The next infrastructure stimulus bill is the right place for lead pipe replacement funding – to create jobs, save money and provide safer water for all

By Joanna Slaney / Published: April 16, 2020

Note to readers: As we all grapple with the grave global health challenge from COVID-19, we want to acknowledge the essential service that the public health professionals at water utilities provide in delivering safe water not only for drinking but for washing our hands and our surroundings.

During the past few weeks, Congress has taken extraordinary measures to provide much-needed emergency relief to people as we collectively struggle with the COVID-19 crises. Over the coming months, lawmakers have said they will turn their attention to providing funding to stimulate the economy with a focus on water infrastructure as a priority. Lead pipe replacement should be an essential part of that effort.

To guide the Congressional effort, EDF and hundreds of others signed onto U.S. Water Alliance’s COVID-19 Relief and Recovery: Guiding Principles to Secure Our Water Future. The four principles are:

  1. Ensure water is reliable and affordable to all
  2. Strengthen water utilities of all sizes
  3. Close the water access gap
  4. Fuel economic recovery by investing in water systems

In line with of our support for these principles, EDF is advocating that Congress provide $45 billion for water utilities to fully replace lead service lines (LSL) – the lead pipes connecting a home to the water main under the street. Today, there are more than nine million homes still serviced by LSLs in the country, exposing millions of children and adults to the myriad of harms associated with lead. For children, these harms include undermining brain development. In adults, lead has been shown to cause heart disease, cancer, and impact the neurological, reproductive, and immune systems. While there is broad consensus that LSLs must be fully removed to protect public health, funding challenges have stymied progress.

Latest Wisconsin data on water service lines provides important insights, reveals over 150,000 lead pipes

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: April 16, 2020

Tom Neltner, J.D. is the Chemicals Policy Director

Note to readers: As we all grapple with the grave global health challenge from COVID-19, we want to acknowledge the essential service that the public health professionals at water utilities provide in delivering safe water not only for drinking but for washing our hands and our surroundings. In the meantime, we are continuing to work towards improved health and environmental protections – including reducing lead in drinking water. We’ll plan to keep sharing developments regarding lead in drinking water that may be useful to you. In the meantime, please stay safe and healthy.

With the comment period now closed on the Environmental Protection Agency’s proposed revisions to its Lead and Copper Rule (LCR), agency staff are busy reviewing the 687 distinct comments submitted to the docket with a goal of finalizing the rule by the end of the year. To help water professionals plan ahead, the cover article in the March edition of Journal AWWA walks readers through the proposal and its implications. It ends with six suggestions to water systems that include developing a service line material inventory and identifying funding strategies to accelerate full lead service line (LSL) replacement.

With this suggestion in mind, we are continuing our work evaluating state efforts to develop LSL inventories by taking a closer look at reporting by Wisconsin municipal and private water utilities[1] to the state Public Service Commission (PSC) for calendar year 2018.[2] Of the other states with mandatory inventory reporting, we have previously covered Illinois in detail and will evaluate Michigan’s newly released reports soon. The only other state with mandatory reporting is California, but it has limited value because it only covers the portion of the service line owned by the utility and excludes the portion on private property.

Best practices for reducing cadmium in food: New review from FDA scientists

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: April 7, 2020

Note to readers: As we all grapple with the grave global health challenge from COVID19, we want to acknowledge the essential services that the professionals at the Food and Drug Administration and in the food production, processing and retail industries provide in continuing to deliver food. In the meantime, we are continuing to work towards improved health protections – including reducing chemicals in food. We’ll plan to keep sharing developments that may be useful to you. In the meantime, please stay safe and healthy.

Two years ago, the Food and Drug Administration (FDA) put cadmium on our radar when the Toxic Elements Working Group included cadmium together with arsenic, lead and mercury as metals affecting children’s neurological development. As part of that effort, FDA committed to look at all four metals across all foods instead of one contaminant, one food at a time. Last year, FDA’s scientists published a peer-reviewed article assessing children’s exposure to lead and cadmium in the diet. They found that spinach, lettuce, sunflower seeds, potato chips and wheat cereal were among the top 10 foods with the highest cadmium concentration.

New review of mitigation strategies

This year, FDA’s scientists published in a peer-reviewed journal a review of mitigation strategies to reduce dietary exposure to cadmium. Because plants uptake cadmium from the soil and “70 to 80% of dietary cadmium intake in humans comes from plant-based food,” the article focuses on methods to “reduce or prevent initial uptake by plants.” The authors explained that cadmium enters the food supply through natural and manmade sources, highlighting that cadmium often is a contaminant in phosphate fertilizers. Cadmium is also a contaminant in zinc used to galvanize steel.

Tightening lead leaching standards for new drinking water fixtures – Opportunity for public comment

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: April 3, 2020

Tom Neltner, J.D. is the Chemicals Policy Director

Update: In September 2020, the joint committee announced it revised the NSF/ANSI/CAN 61 standard.

On May 11, 2020, EDF and EWG jointly filed comments to NSF International supporting proposed changes to the NSF/ANSI/CAN 61 Standard.

We have a legacy of lead in our pipes, our paint, and our soil. These are the most significant sources of human lead exposure and, therefore, draw most of the attention and resources because they are costly to fix. It is also important to limit lead from new sources to avoid adding to that environmental burden. For that reason, EDF has sought, as part of our larger efforts, to reduce the amount of lead that leaches from new plumbing devices such as faucets and fountains.

Thanks to the leadership of California Assembly Member Chris Holden, a collaboration with Environmental Working Group, and a productively and collaboratively engaged Plumbing Manufacturers International (PMI), the trade association that represents the manufacturers that provide 90% of the plumbing products sold in the United States, we are seeing real progress from our efforts. We wanted to update you on two parallel, but related, developments:

  • A proposal to revise the current U.S. consensus national standard NSF/ANSI/CAN 61; and
  • California Assembly Bill AB 2060 to revise 116875 of the California Health and Safety Code.

These changes are needed because the current federal limit of 0.25% of lead by weight is insufficient to ensure that lead levels in drinking water are as low as possible, especially during the first few weeks of use before they are conditioned to the water. With these changes, buyers will be able to identify and purchase new devices that should meet the American Academy of Pediatrics recommended action level of one part per billion.

If all goes as anticipated, the more stringent NSF standard will be in place by the end of the year, manufacturers will begin the process of certifying products to the more protective lead limits, and there will be sufficient certified devices on the market in California to meet the anticipated demand from child care centers.

FDA scientists push back on an industry-funded analysis about bioaccumulation and toxicity of short-chain PFAS

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: April 1, 2020

Note to readers: As we all grapple with the grave global health challenge from COVID19, we want to acknowledge the essential services that professionals at the Food and Drug Administration (FDA) and in the food production, processing and retail industries provide in continuing to deliver food. In the meantime, we are continuing to work towards improved health protections – including reducing chemicals in food. We’ll plan to keep sharing developments that may be useful to you. In the meantime, please stay safe and healthy.

Last year, we reported on a sophisticated analysis performed by FDA’s scientists showing that 5:3 acid, a breakdown product of a short-chain PFAS known as 6:2 fluorotelomer (6:2 FTOH) was slow to be eliminated by the body. The authors concluded that the metabolite was an important biomarker for assessment of long-term exposure to 6:2 FTOH and showed potential bioaccumulative (aka biopersistence[1]) properties. The chemical 6:2 FTOH is a common starting substance in the manufacture of many PFAS polymers, including those used to greaseproof paper and paperboard. As a result, it is a major impurity in, and degradation product of, these polymers.

We are now reporting on two recent publications by the same group of FDA scientists (Kabadi et al.[2] and Rice et al.)[3] in which they not only confirmed their initial findings but also produced new evidence on the behavior of short-chain PFAS when they enter the body. The new evidence highlights:

  • Bioaccumulation: 6:2 FTOH is transformed by the body into several metabolites; one of them, called 5:3 acid, bioaccumulates, and the bioaccumulation is greater with lower exposure to 6:2 FTOH.
  • Toxicity: The toxicity of 6:2 FTOH is concerning and its risk to human health may have been significantly underestimated previously. Data on perfluorohexanoic acid (PFHxA), the industry’s proposed reference chemical for the short-chain PFAS class are not appropriate for assessing the potential health effects of 6:2 FTOH.

The FDA’s scientists reached these important conclusions after reviewing “recently received additional data on 6:2 FTOH and 5:3 acid” and more than a dozen reports on oral toxicity studies that “had been conducted and submitted by industry in support for food contact uses” of short-chain PFAS in addition to a study by the National Toxicology Program. They also called out flaws in industry-funded analyses that reached different conclusions.
