Earlier quoted context omitted.
It seems like the PFAS rules were set in prior administrations [1]. In fact, even in the article you've linked above, the text states: > retaining its maximum contaminant levels for PFOA and PFOS but pulling back on its use of a hazard index and regulatory determinations for additional PFAS Key word being "retaining," indicating the maximum contaminant levels were already in place prior to the change mentioned here.…
Absolutely. https://www.epa.gov/sites/default/files/2019- 02/documents/pfas_action_plan_021319_508compliant_1.pdf Trump's first term. February of 2019. Andrew Wheeler's EPA. You'll also notice that the document lays out planned action dates bleeding generously into Biden's term, and for which Biden later took credit in the document you shared. This is shameful, and sadly normal presidential behavior, taking credit fo…
Firstly, this is a completely unnecessary comment. My searches were specifically regarding finding the enactment of specific PFA limits. I will acknowledge to not spending that much time looking at it, as you claimed to already have a source and I was curious to see what it was.
But to the point, this document does not outline or set limits on PFAS in drinking water. It's an action plan for measuring and creating limits, but does not itself enforce anything. In fact, every subsequent search I've done has shown that the 2024 Final Rule was the first point at which any limits were put into action.
Quoting directly, the document states that one of the steps being taken is:
> Initiating steps to evaluate the need for a maximum contaminant level (MCL) for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS);
In other words, it outlines a plan for the research that is used to 1) determine if MCL should be set, and 2) what, if any, it should be set to. Notably, it does it not itself set that limit or come to a conclusion about what it should be.
Further, this research appears to be a continuation of research released in 2016 [1], which was the first time that a guideline (but not a mandate) was set. This would, of course, be prior to Trump's first administration. This is suggested in the document itself, where it outlines that this document is part of a series of actions beginning in 2015/2016, as well as callouts to specific research in the 2016 article linked below.
So the facts seem to show that: 1) The first guideline was set in 2016. It was not a law at this time. 2) Research continued to identify next steps for setting a standard, which were codified and shared in the 2019 article you linked 3) The 2024 Final Rule put a MCL into action for PFAS.
Take from that chain of events what you will, but the initial accusations of "political bias" seem unfounded here.
