EJSCREEN originally provided extensive documentation and help through the EJSCREEN website (e.g., overviews and how to interpret reports) and documents available for download, such as the User Guide (how to use the app) and the Technical Documentation (how indicators are calculated).
In 2025, before EPA took down the EJSCREEN website and documents, they were archived by the Wayback Machine. The webpages and documents on archive.org load slowly, so copies of some key documents are also made available here, for easy access.
Below are links to archived copies of selected publicly-available EJSCREEN webpages and documents from the U.S. Environmental Protection Agency (EPA) as of 2025, when the EPA-hosted open source EJAM project was archived by the Wayback Machine (an initiative of the Internet Archive) and by EJAM-related repositories.
