Biden EPA moves closer to total ban of toxic weedkiller DCPA
‘Most serious risk to fetuses of pregnant individuals,’ warns agency, releasing health assessment now because ban may take years
The Environmental Protection Agency this week released part of its health assessment
showing the weedkiller DCPA, sold under the brand Dacthal and widely used on U.S. food for decades, poses serious risks to humans, particularly those who are pregnant.
The EPA identified concerns about DCPA in its assessment of occupational and residential exposure. As a result, now the agency is considering banning all uses of the herbicide, which is used on produce and on turf for golf courses and athletic fields. The assessment refers to a new study showing DCPA can harm the developing fetus in animals exposed at very low doses, the same levels agricultural workers can be exposed to.
The EPA says it is releasing the health assessment now to inform the public about the potential risks of DCPA, because banning the chemical’s use on produce could take many years.
“We applaud the EPA for informing the public that this dangerous pesticide is in food and water and is highly toxic, in case people want to take steps to avoid exposure, since regulation could take years,” said Ken Cook, president and co-founder of EWG.
EWG’s 2022 Shopper’s Guide to Pesticides in Produce™, which relies on pesticide tests conducted by the Department of Agriculture’s Pesticide Data Program, found DCPA widespread on kale, collards and mustard greens. EWG’s own tests confirmed this data.
by EWG scientists identified DCPA as a pesticide of concern due to its toxicity and harm to the thyroid and its classification as a possible cause of cancer. According to EWG’s analysis, about 15,000 pounds were applied each year on farm fields in Ventura County, Calif., between 2016 and 2018. Farmworkers, their families and other residents are at risk as a result.
“By now the American public should assume that just because a pesticide is legal doesn’t mean it is safe. DCPA is the most recent in a very long line of examples,” said Cook.
Potential for ‘serious’ health risks
DCPA was first registered in the U.S. in 1958 for use on turf. It has been used on dozens of food crops, and its breakdown products have contaminated groundwater across the country.
In 1995, the EPA said DCPA might cause cancer in humans,
, and in 2009 it was banned by the European Union. EWG has urged the Biden administration to ban the herbicide.
The new EPA health assessment comes after repeated attempts over the past decade to get DCPA’s manufacturer, agrochemical giant AMVAC, to prove the weedkiller does not pose a risk to human health. The company ignored those requests while continuing to press the agency to allow the chemical to be used on non-organic produce.
“Given the potential for serious, permanent, and irreversible health risks, EPA is considering whether feasible mitigation measures exist that would address these potential risks or whether canceling the registration of all products containing DCPA is necessary,” says the assessment.
“Given the potential that cancellation of this pesticide
could take several years to complete, EPA is releasing this assessment in order to provide the public with timely information about its risks,” the EPA says.
DCPA can drift from the fields where it is sprayed and is regularly detected in dust samples from the homes of farmworkers and those living in agricultural areas. A 2021 study
found an association between DCPA in dust samples and increased risk of childhood leukemia.
More than 50 percent of adolescent girls from farmworker communities in the Salinas Valley were found to have been exposed to DCPA in a 2019 study
led by scientists at the University of California at Berkeley School of Public Health.
"The EPA has begun to take significant steps toward protecting the most vulnerable populations from this highly toxic weedkiller,” said Alexis Temkin, Ph.D., senior toxicologist at EWG.
“Yet the new data showing the risks linked to DCPA exposure during pregnancy require immediate action to stop exposure to this harmful crop chemical,” Temkin said.

Billionaire Palantir Co-Founder Pushes Return of Public Hangings as Part of 'Masculine Leadership' Initiative
"Immaturity masquerading as strength is the defining personal characteristic of our age," said one critic in response.
Dec 07, 2025
Venture capitalist Joe Lonsdale, a co-founder of data platform company Palantir, is calling for the return of public hangings as part of a broader push to restore what he describes as "masculine leadership" to the US.
In a statement posted on X Friday, Lonsdale said that he supported changing the so-called "three strikes" anti-crime law to ensure that anyone who is convicted of three violent crimes gets publicly executed, rather than simply sent to prison for life.
"If I’m in charge later, we won’t just have a three strikes law," he wrote. "We will quickly try and hang men after three violent crimes. And yes, we will do it in public to deter others."
Lonsdale then added that "our society needs balance," and said that "it's time to bring back masculine leadership to protect our most vulnerable."
Lonsdale's views on public hangings being necessary to restore "masculine leadership" drew swift criticism.
Gil Durán, a journalist who documents the increasingly authoritarian politics of Silicon Valley in his newsletter "The Nerd Reich," argued in a Saturday post that Lonsdale's call for public hangings showed that US tech elites are "entering a more dangerous and desperate phase of radicalization."
"For months, Peter Thiel guru Curtis Yarvin has been squawking about the need for more severe measures to cement Trump's authoritarian rule," Durán explained. "Peter Thiel is ranting about the Antichrist in a global tour. And now Lonsdale—a Thiel protégé—is fantasizing about a future in which he will have the power to unleash state violence at mass scale."
Taulby Edmondson, an adjunct professor of history, religion, and culture at Virginia Tech, wrote in a post on Bluesky that the rhetoric Lonsdale uses to justify the return of public hangings has even darker intonations than calls for state-backed violence.
"A point of nuance here: 'masculine leadership to protect our most vulnerable' is how lynch mobs are described, not state-sanctioned executions," he observed.
Theoretical physicist Sean Carroll argued that Lonsdale's remarks were symbolic of a kind of performative masculinity that has infected US culture.
"Immaturity masquerading as strength is the defining personal characteristic of our age," he wrote.
Tech entrepreneur Anil Dash warned Lonsdale that his call for public hangings could have unintended consequences for members of the Silicon Valley elite.
"Well, Joe, Mark Zuckerberg has sole control over Facebook, which directly enabled the Rohingya genocide," he wrote. "So let’s have the conversation."
And Columbia Journalism School professor Bill Grueskin noted that Lonsdale has been a major backer of the University of Austin, an unaccredited liberal arts college that has been pitched as an alternative to left-wing university education with the goal of preparing "thoughtful and ethical innovators, builders, leaders, public servants and citizens through open inquiry and civil discourse."

Hegseth Defends Boat Bombings as New Details Further Undermine Administration's Justifications
The boat targeted in the infamous September 2 "double-tap" strike was not even headed for the US, Adm. Frank Bradley revealed to lawmakers.
Dec 07, 2025
US Defense Secretary Pete Hegseth on Saturday defended the Trump administration's policy of bombing suspected drug-trafficking vessels even as new details further undermined the administration's stated justifications for the policy.
According to the Guardian, Hegseth told a gathering at the Ronald Reagan presidential library that the boat bombings, which so far have killed at least 87 people, are necessary to protect Americans from illegal drugs being shipped to the US.
"If you’re working for a designated terrorist organization and you bring drugs to this country in a boat, we will find you and we will sink you," Hegseth said. "Let there be no doubt about it."
However, leaked details about a classified briefing delivered to lawmakers last week by Adm. Frank Bradley about a September 2 boat strike cast new doubts on Hegseth's justifications.
CNN reported on Friday that Bradley told lawmakers that the boat taken out by the September 2 attack was not even headed toward the US, but was going "to link up with another, larger vessel that was bound for Suriname," a small nation in the northeast of South America.
While Bradley acknowledged that the boat was not heading toward the US, he told lawmakers that the strike on it was justified because the drugs it was carrying could have theoretically wound up in the US at some point.
Additionally, NBC News reported on Saturday that Bradley told lawmakers that Hegseth had ordered all 11 men who were on the boat targeted by the September 2 strike to be killed because "they were on an internal list of narco-terrorists who US intelligence and military officials determined could be lethally targeted."
This is relevant because the US military launched a second strike during the September 2 operation to kill two men who had survived the initial strike on their vessel, which many legal experts consider to be either a war crime or an act of murder under domestic law.
Rep. Jim Himes (D-Conn.), the ranking member of the House Permanent Select Committee on Intelligence, watched video of the September 2 double-tap attack last week, and he described the footage as “one of the most troubling things I’ve seen in my time in public service.”
“Any American who sees the video that I saw will see its military attacking shipwrecked sailors,” Himes explained. “Now, there’s a whole set of contextual items that the admiral explained. Yes, they were carrying drugs. They were not in position to continue their mission in any way... People will someday see this video and they will see that that video shows, if you don’t have the broader context, an attack on shipwrecked sailors.”
While there has been much discussion about the legality of the September 2 double-tap strike in recent days, some critics have warned that fixating on this particular aspect of the administration's policy risks taking the focus off the illegality of the boat-bombing campaign as a whole.
Daphne Eviatar, director for security and human rights for Amnesty International USA, said on Friday that the entire boat-bombing campaign has been "illegal under both domestic and international law."
"All of them constitute murder because none of the victims, whether or not they were smuggling illegal narcotics, posed an imminent threat to life," she said. "Congress must take action now to stop the US military from murdering more people in the Caribbean and Eastern Pacific."

Leaked Memo Shows Pam Bondi Wants List of 'Domestic Terrorism' Groups Who Express 'Anti-American Sentiment'
"Millions of Americans like you and I could be the target," warned journalist Ken Klippenstein of the new memo.
Dec 07, 2025
A leaked memo written by US Attorney General Pam Bondi directs the Department of Justice to compile a list of potential "domestic terrorism" organizations that espouse "extreme viewpoints on immigration, radical gender ideology, and anti-American sentiment."
The memo, which was obtained by journalist Ken Klippenstein, expands upon National Security Presidential Memorandum-7 (NSPM-7), a directive signed by President Donald Trump in late September that demanded a "national strategy to investigate and disrupt networks, entities, and organizations that foment political violence so that law enforcement can intervene in criminal conspiracies before they result in violent political acts."
The new Bondi memo instructs law enforcement agencies to refer "suspected" domestic terrorism cases to the Joint Terrorism Task Forces (JTTFs), which will then undertake an "exhaustive investigation contemplated by NSPM-7" that will incorporate "a focused strategy to root out all culpable participants—including organizers and funders—in all domestic terrorism activities."
The memo identifies the "domestic terrorism threat" as organizations that use "violence or the threat of violence" to advance political goals such as "opposition to law and immigration enforcement; extreme views in favor of mass migration and open borders; adherence to radical gender ideology, anti-Americanism, anti-capitalism, or anti-Christianity; support for the overthrow of the United States Government; hostility towards traditional views on family, religion, and morality."
Commenting on the significance of the memo, Klippenstein criticized mainstream media organizations for largely ignoring the implications of NSPM-7, which was drafted and signed in the wake of the murder of right-wing activist Charlie Kirk.
"For months, major media outlets have largely blown off the story of NSPM-7, thinking it was all just Trump bluster and too crazy to be serious," he wrote. "But a memo like this one shows you that the administration is absolutely taking this seriously—even if the media are not—and is actively working to operationalize NSPM-7."
Klippenstein also warned that NSPM-7 appeared to be the start of a new "war on terrorism," but "only this time, millions of Americans like you and I could be the target."
