Status of EJAM package in 2026
See ejanalysis.org/status for more information.
In 2025, content related to what had been the USEPA-hosted open source R package EJAM was archived.
Ongoing development since then is not associated with EPA, and that development including any open source contributions, has taken place in a separate repository, called ejanalysis/EJAM, a non-EPA, detached fork.
documentation

Until mid-2025, datasets had been in a repository archived and/or unpublished in mid-2025 (USEPA/ejamdata) with no plans for it to be further updated by EPA.
