EPA proposal for pesticide tied to reproductive harm lands back with Trump

US environmental regulators are planning to change allowable levels of a weedkiller linked with reproductive health problems to a concentration critics say discounts years of documented health and environmental risks — potentially marking a new battlefront within the Trump administration.

The proposal by the Environmental Protection Agency (EPA), which was put forth in late 2024 under the Biden administration, would allow concentrations of the herbicide atrazine up to 9.7 parts per billion (ppb) in streams and lakes before any mitigation efforts were required.

That is nearly three times higher than the level of 3.4 ppb proposed by the EPA in 2016 and reiterated by the agency as proper in 2022. But it is lower than a level pushed for under the prior Trump administration. It is also lower than the longtime benchmark of 10 ppb that was in place from 2011-2019, and lower than atrazine maker Syngenta says is necessary.

The agency’s move has been met with outrage by environmental health advocates who say industry influence is overriding solid science, and years of fighting to reduce atrazine contamination of waterways is in jeopardy. (Read the rest of the story.)

Amid series of rapid-fire policy reversals, Trump quietly withdraws proposed limits on PFAS

Amid a flurry of actions curtailing Biden’s environmental policies, the administration of newly inaugurated President Donald Trump last week withdrew a plan to set limits on toxic PFAS chemicals in industrial wastewater.

The draft rule, which the US Environmental Protection Agency (EPA) sent to the White House for review in June, was seen as a precedent-setting move by reducing allowable discharges of per- and polyfluoroalkyl substances (PFAS), a class of chemicals that have been linked to an array of health problems.

“It is abundantly clear that this action was taken to benefit the chemical industry – and every American will suffer for it,” said Kyla Bennett, director of science policy at the watchdog group Public Employees for Environmental Responsibility. “PFAS contamination is already a national health crisis, and this will force states to try and fill the regulatory void left by EPA’s failure. “

The decision to withdraw the draft rule came as Trump issued an executive order to freeze any new federal regulations pending review. (Read the rest of the story.)

Close to 30 million Americans face limited water supplies, government report finds

Nearly 30 million people are living in areas of the US with limited water supplies as the country faces growing concerns over both water availability and quality, according to a new assessment by government scientists.

The US Geological Survey (USGS), which is part of the Department of the Interior, issued what it said was a first-of-its-kind report last week, with USGS Director David Applegate warning of “increasing challenges to this vital resource.” The Jan. 16 report, based on data from 2010 to 2020, examines not only water supplies but also demand patterns and water quality. The report showed that most of the country had supplies that exceeded demand during the period examined, but worrisome trends were noted.

“Water availability is an issue everywhere in our country and beyond,” Lori Sprague, USGS national program manager for the water availability assessment, said in a webinar presenting the report. “It raises the question – do we have enough water to sustain our nation’s economy, ecosystems and drinking water supplies?” (Read the rest of the story.)
