actual scienceMeanwhile, the incoming chair of the Senate environmental committee in a hearing last week promised to target portions of new PFAS regulations put in place over the last year, a top priority for Trump’s chemical and water utility industry allies.
The Republican House committee on oversight and accountability chair, James Comer, charged in his letter that scientific integrity policies would be used by EPA scientists to “hamstring the incoming Trump administration’s ability to implement their own executive agendas”.
Comer ordered the EPA’s Regan to turn over reams of documents detailing the policies and their application.
Ruch said the attack points to two certainties: a stepped-up attack on agency scientists who contradict Trump in the second administration, and a crackdown on research produced by federal scientists.
“There will be blood,” Ruch added.

Several technologies are currently available for remediating PFASs in liquids. These technologies can be applied to drinking water supplies, groundwater, industrial wastewater, surface water, and other applications such as landfill leachate. Influent concentrations of PFASs can vary by orders of magnitude for specific media or applications. These influent values, along with other general water quality parameters (for example, pH) can influence the performance and operating costs of the treatment technologies. The technologies are:
Photodegradation[223]
Foam fractionation[224]
Sorption
Granular activated carbon
Biochar
Ion exchange
Precipitation/flocculation/coagulation
Redox manipulation (chemical oxidation and reduction technologies)
Membrane filtration
