Exchange Now Includes Biological, Habitat Data

The U.S. Environmental Protection Agency Office of Water has released Water Quality Exchange (WQX ) version 2.0, a data transfer system that allows states, tribes, and other organizations to share their biological and habitat monitoring results.

Since February 2007, WQX version 1.0 has provided a way for states, tribes, and other organizations to share physical, chemical, and fish tissue water monitoring data.

Because many monitoring programs use biological and habitat data as the basis for assessing water quality, WQX version 2.0 enhances the richness of information available for data sharing, analysis, and improved decision making by watershed managers. All data shared using the WQX framework can be accessed on-line in the STORET Data Warehouse, EPA's repository for water quality data. Visit for more information.
