"Watchdog finds PFBS toxicity value was altered in 2021 report, as scientists say episode part of ‘larger rot at the agency’".
"Trump administration appointees at the Environmental Protection Agency (EPA) meddled in agency science to weaken the toxicity assessment of a dangerous chemical, a new report by the US body’s internal watchdog has found.
In response to what it labeled “political interference”, the Biden administration in February 2021 pulled the assessment, republished it months later using what it said is sound science, and declared it had resolved the issue.
But EPA scientists who spoke to the Guardian say several employees willingly worked with the Trump appointees to weaken the assessment, and they were never reprimanded or fired.
The scientists say the controversy is part of a deeper problem afflicting the EPA: industry influence on career staff, and an unwillingness from the EPA to address it."
