Industrial chemicals threaten hunting and fishing traditions

By Shannon Kelleher

For more than a century, members of the indigenous Penobscot Nation, who live along the Maine river from which they take their name, have mourned the loss of the migratory fish that sustained their ancestors.

Dams built by developers in the 19th and early 20th centuries along the Penobscot River cut off access to the ocean, preventing native fish from returning each year to spawn in their historic habitats.

A years-long restoration project was completed in 2016, reopening 2,000 miles of river to Atlantic salmon and other fish considered important nutritional sources for the people of the region as well as fish-eating birds and mammals, including eagles and river otters. Eleven species of native migratory fish returned to the Penobscot River due to the restoration project.

“We were very excited,” said Daniel Kusnierz, the tribe’s water resources program manager. “These would have been the species the tribe would have relied on heavily for food.”

But the celebration was short-lived: Though the fish have returned, researchers from the Penobscot Nation and government agencies have documented an array of toxic chemicals contaminating them, including dreaded per- and polyfluoroalkyl substances linked to various cancers and other health problems.

Known as PFAS, or “forever chemicals,” the class of industrial chemicals is almost impossible to eradicate and is increasingly documented in fish and other wildlife around the world. The plight of the Penobscot Nation is yet another example of how people everywhere are finding it increasingly difficult to escape the legacy of industrial pollution that threatens human and environmental health.

PFAS contaminating 83% of tested waterways, study finds

Clean water advocacy groups said this week that they have found toxins linked to cancer and other health problems in more than 80% of tested watersheds around the United States, adding to the growing body of evidence about the pervasiveness of per- and polyfluoroalkyl substances, better known as PFAS.

Results of the study, which was carried out by the nonprofit organization Waterkeeper Alliance, were released Tuesday. The group said PFAS toxins were detected in 95 of 114 watersheds tested, and some samples were found to contain levels of PFAS thousands of times higher than the levels considered safe for drinking water by the Environmental Protection Agency (EPA.)

Maryland, Georgia, South Carolina, and Florida were among the states with the highest number of water samples containing PFAS.

The results “demonstrate that existing laws are inadequate for protecting us,” said Marc Yaggi, CEO of Waterkeeper Alliance.

The study is the first nationwide surface water quality survey to measure PFAS, and probably the most extensive survey of PFAS presence in surface waters that has ever been conducted in the US, according to the group.

One type of PFAS known as PFOA is considered a likely human carcinogen. Another type, PFOS, is known to accumulate in humans and cause liver damage and birth defects in lab animals. Both were detected in 69% of samples.

The report noted that PFOA was detected above the EPA Interim Health Advisory Level of 0.004 ppt in samples taken in waterways located in 26 states and D.C. The highest level detected was 847 ppt in a sample from Kreutz Creek, Pennsylvania. PFOS was detected above the EPA advisory levels in 28 states and D.C. The highest level detected was 1,364.7 ppt in a sample from Piscataway Creek, Maryland.

High levels of toxic PFAS found in pesticides used in farming

By Shannon Kelleher

Widely used pesticides contain concerning levels of toxic “forever chemicals” called PFAS, adding to concerns about the human health risks posed by pesticides that are used in growing food, according to a study published last week.

The study found a type of PFAS called PFOS at levels hundreds of thousands of times higher than the Environmental Protection Agency (EPA) considers safe in 6 out of 10 insecticides tested, including malathion, one of the most commonly applied insecticides in the world.

PFOS was found at levels ranging from 3,920,000 to 19,200,000 parts-per-trillion (ppt), far higher than the EPA’s health advisory for PFOS in drinking water, which is set at 0.02 ppt. PFOS is no longer manufactured in the US and has been linked to cancer, as well as problems with the liver, thyroid, and immune system.

PFAS chemicals, including PFOS, were also found in soil samples, corn kernels, string beans, and peanuts that had been sprayed with pesticides at a government research laboratory in Lubbock, Texas, where the study was conducted.

“The level of PFAS absorption by plants detected in this study suggests that this exposure pathway poses a major threat to the safety of our food supply,” Tim Whitehouse, executive director of the government watchdog group PEER, wrote in a Sept. 26 letter to EPA Administrator Michael Regan.

“For this reason, it is quite possible that PFAS in our food is a bigger PFAS exposure pathway than water. This threat is not merely to the safety of U.S. agriculture but of the world’s food supply, as these pesticides are widely applied in other countries,” Whitehouse wrote in the letter.

Interview: Lawyer Rob Bilott on PFAS “worldwide public health threat” and his letter to President Biden

Last month, an Ohio court certified a class action lawsuit brought by lawyer Rob Bilott that would cover seven million people – and at some point potentially everyone living in the United States – who have been exposed to certain hazardous chemicals known as Per- and Polyfluoroalkyl Substances or PFAS. The chemicals have been linked to cancer, birth defects, kidney disease and a range of other human health problems. They are dubbed “forever chemicals” because they do not naturally break down, persisting indefinitely in the environment. Two types of PFAS – PFOA and PFOS – have been found to be so harmful that they are being phased out of use. In addition to 3M, the class action lawsuit names ten other companies that produce PFAS, which are used to make cookware, food packaging, water-resistant fabrics, firefighting foam and other products. The Biden administration last year pledged to undertake a massive PFAS mitigation strategy at a cost of more than $10 billion.

You have spent 20 some years now focused on exposing the danger of a class of chemicals we call PFAS, using litigation to try to hold companies involved in spreading PFAS accountable, and pressuring regulators to step up and do more to protect the public. You’ve written a book, “Exposure,” been featured in the NY Times as “The Lawyer Who Became DuPont’s Worst Nightmare” and your legal battle has been made into a Hollywood movie called “Dark Waters,” as well as a documentary. Why are you so passionate about this issue?
