Environmental models are used to help guide research and policies at EPA. Modeling provides an abundance of information and can impact programmatic decision making. It allows a small or large amount of data to project details beyond boundaries of the individual values.

Within EPA, the Environmental Modeling (E-Mod) Community of Practice (CoP) helps further modeling at EPA by discussing and sharing current and innovative modeling practices. The E-Mod CoP brings together modeler developers, users and managers from across EPA to collaborate and help solve integrated environmental modeling challenges.

Below is a list of some models and modeling programs at EPA.
