New Report: Toxic Consequences – Trump’s Attacks on Chemical Safety Put Our Health at Risk

By Sam Lovell / Published: June 17, 2019

Today, EDF released a report detailing the major threats to public health and future generations from the Trump Environmental Protection Agency’s (EPA) attacks on the 2016 chemical safety law. Just three years after Congress passed bipartisan legislation, the Lautenberg Act, to overhaul the Toxic Substances Control Act (TSCA), implementation of the law has gone dangerously off the rails – putting public health at risk.

“At almost every turn, the Trump administration has failed to live up to the letter and spirit of the historic bipartisan reform of TSCA that Congress passed in 2016. Toxic chemicals can cause cancers and other life-threatening illness. The American people expect the Environmental Protection Agency to live up to its mission and to protect them from these threats.  At the three-year anniversary of our overwhelmingly bipartisan reform of TSCA, EPA continues to ignore expert scientific staff and walk back protections for workers and consumers. ” said Senator Tom Udall.  “EPA leaders – starting with Andrew Wheeler – must change course, commit themselves to protecting the public, and carry out the Lautenberg Act as Congress wrote it.”

The report notes that recent history holds countless stark examples of what can happen when chemical risks are not adequately addressed. We risk making similar mistakes unless the current EPA fundamentally changes course in its implementation of the law. The Trump Administration is allowing new chemicals onto the market with little or no health information and only cursory safety reviews; ignoring real-world exposures when evaluating chemicals already in use today; blocking needed restrictions on dangerous uses of toxic chemicals; and denying the public access to health information on chemicals. These are not merely process problems: the consequences of the Trump EPA’s actions will be felt by our children and subsequent generations.

FDA finds surprisingly high levels of PFAS in certain foods – including chocolate cake

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: June 3, 2019

[Update: FDA has published a webpage on PFAS and released the data for the studies discussed in this blog].

Tom Neltner, J.D., Chemicals Policy Director and Maricel Maffini, Ph.D., Consultant

As reported by the Associated Press today, at a conference last week in Helsinki, Finland, the U.S. Food and Drug Administration (FDA) presented the results of three studies it conducted of 16 per- and poly-fluoroalkyl substances (PFAS) in various foods. A friend who attended the conference sent us photos of the poster. The results for samples of meat and chocolate cake purchased by the agency in October 2017 as part of its ongoing Total Diet Study (TDS) jumped out at us as surprisingly high and worth further investigation:

  • 17,640 parts per trillion (ppt) of perfluoro-n-pentanoic acid (PFPeA) in chocolate cake with icing. These levels suggest that the cake was contaminated from the intentional use of the chemical to greaseproof paper that contacted the cake rather than from an environmental source. We cannot find any evidence that FDA ever reviewed the safety of PFPeA as a food contact substance – meaning the manufacturer may have secretly designated it as Generally Recognized as Safe (GRAS). We also found little evidence – good or bad – of the health risks posed by this PFAS. We have reached out to FDA to learn more, but as of this blog posting the agency has not yet responded. This chemical was also found in chocolate milk at 154 ppt.
  • Nearly half (10 of 21) meat samples had quantifiable levels of perfluoroctanesulfonate (PFOS) with concentrations ranging from 134 ppt in a frankfurter to 865 ppt in tilapia. Unlike the chemical in chocolate cake, PFOS has been extensively studied because of widespread environmental contamination, especially around the facilities in Alabama and Minnesota where it was previously produced. It is associated with increased cholesterol, thyroid disease, testicular cancer, and decreased birth weight. While comparisons are complicated, the PFOS levels found in some of these meats were far greater than the 70 ppt health advisory set by the Environmental Protection Agency (EPA) for drinking water in May 2016. Two years later, the Centers for Disease Control and Prevention (CDC) proposed limits that are almost 7 times more protective than EPA’s, partly because more recent studies indicate the chemical may undermine the effectiveness of vaccines. Production of PFOS in the United States reportedly ended in 2002, though it is still made overseas and may have been imported paper. In 2016, FDA removed its approval to greaseproof paper with PFOS.

FDA’s poster also showed testing results from food produced around two PFAS contaminated areas. FDA found most of the 16 PFAS at varying levels measured in produce sold in farmer’s markets downstream of a PFAS production facility in the Eastern U.S. – presumably Chemours’ plant in North Carolina. The highest produce sample had 1,200 ppt and was purchased within 10 miles downstream of the production plant and short-chain PFAS were prevalent.

The other contaminated area was a dairy farm near an air force base in New Mexico. FDA found many of the 16 PFAS in the water and silage used to feed the cows but PFOS was the most prevalent among a few PFAS measured in the milk with levels higher than 5000 ppt. The agency also detected several PFAS in cheese produced by the farm in lower amounts than the milk. Many of the PFAS are likely from aqueous film forming foam (AFFF) used to fight fire and conduct firefighting training at the Air Force base.

What dense sensor networks can teach us about air pollution

By Maria Harris / Published: May 21, 2019

Maria Harris is an Environmental Epidemiologist.

It all started with a challenge in 2013: how to engineer pollution-sensing balloons. Thomas Kirchstetter, Adjunct Professor at the University of California, Berkeley and the Director of the Energy Analysis and Environmental Impacts Division at Lawrence Berkeley National Lab, wanted to attach pollution sensors to high altitude weather balloons to measure how black carbon moves throughout the atmosphere.

Black carbon “soot” is emitted from diesel engines on trucks, locomotives, and ships, as well as from wildfires and the combustion of solid fuels for cooking and heating. But available technology to measure this air pollutant wasn’t well suited to handle the changes in temperature and humidity experienced during its ascent through the atmosphere or affordable enough to scale. So, he and Berkeley graduate students Danny Wilson and Julien Caubel researched what it would take to create their own.

Meanwhile, Kirchstetter had been in touch with Joshua Apte, assistant professor at the University of Texas at Austin, about his work leading Environmental Defense Fund’s mobile pollution monitoring study using Google Street View cars to measure air quality in Oakland. Apte asked Kirchstetter to support the team’s analysis as they examined how pollution concentrations varied from block to block—including black carbon. That’s when a lightbulb went off for Kirchstetter.

Traffic pollution causes 1 in 5 new cases of kids’ asthma in major cities: How data can help

By Ananya Roy / Published: April 29, 2019

City leadership can ill afford to ignore this issue and must strive for opportunities to prevent new cases of asthma.

[/pullquote]

A landmark new study shines a light on the massive impact of vehicular air pollution on the health of our children. The study estimates that nitrogen dioxide (NO2) – a key traffic air pollutant – leads to approximately 4 million new asthma cases in children across the globe, or 1 in 10 new cases.

To address this pervasive threat, leaders need local data to create targeted approaches and policies. That’s why Environmental Defense Fund (EDF) is leveraging sensor technology to develop novel methods to measure and map air pollution – including NO2 concentrations – block by block in cities across the world, from Oakland to Houston to London.

Cities bear the worst burden

The study, released this month in The Lancet Planetary Health, finds that children living in cities are most at risk of asthma due to NO2 pollution. A staggering 90% of all new cases due to traffic were in urban and adjoining suburban areas.

How toxic is oilfield wastewater? New paper highlights gaps in our understanding.

By EDF Blogs / Published: April 17, 2019

This post originally was published on the Energy Exchange Blog.

By Cloelle Danforth and Nichole Saunders.

Jennifer McPartland contributed to this post.

Collaborative research is a critical element for identifying unforeseen risks associated with using the oil industry’s wastewater outside the oilfield. That’s the recommendation of a new peer-reviewed paper accepted this week in the Journal of Integrated Environmental Assessment and Management (IEAM).

The paper comes at a crucial moment for the oil and gas industry, which generates some 900 billion gallons of salty, chemical-filled water (also called produced water) each year. Traditionally, companies dispose of this wastewater deep underground where it is less likely to cause contamination. But economics and water scarcity are forcing questions about other ways to treat, reuse and even repurpose this wastewater. In fact, the Environmental Protection Agency (EPA) will release a report very soon that could make it more common for companies to discharge their wastewater into rivers and streams.

The IEAM paper outlines the conclusions of a multi-day toxicity workshop where experts from the oil and gas industry, academia, government and the environmental community collectively identified key knowledge gaps associated with this waste stream and determined tools, technologies and methods needed to help close those gaps.

EDF analysis: Lead service lines in Illinois communities

By Tom Neltner, Senior Director, Safer Chemicals Initiative / Published: April 4, 2019

Tom Neltner, J.D., Chemicals Policy Director

Building statewide, comprehensive inventories of lead service lines (LSLs) in community water systems (CWSs) is a critical part of any effort to eliminate lead pipes. With a solid inventory, states can conduct a credible needs assessment and engage the public in supporting community efforts to replace LSLs.

In January 2017, the Illinois legislature passed a law designed to reduce children’s exposure to lead in drinking water. It included a requirement that CWSs submit annual reports to Illinois Environmental Protection Agency (IEPA) regarding a “water distribution system material inventory” by April of each year. EDF sees Illinois’s approach to developing an inventory as a model to be considered by other states because it:

  • Requires all CWS to report (unlike Indiana which had a well-designed one-time voluntary survey but only a 57% response);
  • Covers the entire service line (unlike California which ignored the portion of the service line on private property); and
  • Requires annual updates to track progress, especially in reducing the number of service lines with unknown materials (unlike Michigan which requires updates only every five-years).

In August 2018, IEPA released a summary of the first year submissions and has updated it several times. IEPA indicated that 95% of CWSs submitted reports and provided totals of each type of piping material reported with 414,895 LSLs and 1,504,748 of unknown material. At the time, the agency did not provide information on what each CWS reported.

Making totals public is important but does little to engage the public in understanding what the information means for their community. But earlier this week, IEPA published an online tool, which allows residents to search for their water system and download the data for individual reports of the types of materials currently reported by their water system.  EDF also received the information pursuant to a Freedom of Information request. Click here to see the data for all the CWSs in a spreadsheet. We also used an EPA database to identify the 84 CWSs that did not comply with the law.
