From the Environmental Data and Governance Initiative (EDGI):
There have been substantial changes to the EPA website during the Trump administration that negatively impact the quality of information provided to the public. Most, but not all, of the changes that EDGI has observed occurred under Administrator Pruitt, but the Wheeler administration has not replaced removed resources and has continued problematic practices that undermine public access to crucial environmental information.
The most blatant examples of web resource changes that align with partisan political objectives and undermine public access to scientific information are the removals of several websites within EPA.gov.

In addition to these wholesale removals of valuable information, EPA has changed the language on various webpages to make content less clear, and in some cases less accurate. Examples, provided with notes in the list below, include such things as replacing the words “greenhouse gases” with “air pollutants,” and rewriting a mission statement to assert the office has goals of economically achievable standards for industry rather than standards to achieve clean water.
