There are many different styles for citing EPA web pages. The citation may depend on the style preferred by your teacher, instructor, or reviewer. Government documents are different from articles or books, because they do not always have a clear author. For that reason, they are usually cited differently. In the case of EPA, the majority of our pages do not have a single author.
Purdue’s Online Writing Lab provides citation guidance for various publication styles and includes information about citing government documents.

Lastly, to find the publish date for an EPA web page, scroll down to the bottom of the page, and look in the footer underneath the “Follow” heading. Under all of the social media icons the page will say “Last Updated On…” This date will be different for each page, and it indicates the last time that page was updated.
