Water Quality Models

Enhanced Stream Water Quality Model, Windows (QUAL2E)

We no longer support QUAL2E for windows.

A new version of the QUAL program, called QUAL2K, works with all Windows operating systems.

A dos version of the QUAL2E program is also available from EPA's Center for Exposure Assessment Modeling (CEAM)
