I read the whole article. There isn’t much more context beyond the article headline apart from an unconvincing denial from the press secretary.

Ditto.

The sources appear to be a combination of anonymous and the EPA employee union leader. The administration is flatly denying that such a meeting happened.

The only added context is that the studies being stopped are around water safety levels. PFAS are specifically called out as the Trump admin immediately pulled back PFAS regulations.
