Frequent Questions

How can The Substance Registry System (SRS) help me?

The Substance Registry System (SRS) can help you discover information about substances that are tracked or regulated at EPA. It can point to sources at EPA where you can find additional data about the substance. And the SRS can tell you which synonym for a substance is used by that program office. SRS is a one-stop resource for finding health and safety fact sheets or other information about a substance developed by other federal, state, or international organization.  You can access SRS at: www.epa.gov/srs
