The US Environmental Protection Agency's mission is to protect human health and the environment. We develop models, tool, data sets, libraries, and applications to help serve our mission.

As part of the government's open source initiative, we publish software here and are open to recieving contributions depending on the project. Please see each repository's CONTRIBUTING.md file for how you can help.

Check out EPA's public open job postings usabjos.gov.

Here are some interesting topics to explore:

  • ord -- EPA's office of research and development develops models and tools to study environmental issues
  • ow -- EPA's office of water studies and regulates the US's waterways
  • oar -- EPA's Office of Air and Radiation studies and regulates air pollution and emissions
