EPA's Office of Water has announced the release of Water Quality Exchange (WQX ) version 2.0, a data transfer system which now 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.
