The Water Quality Data Exchange (WQDE) is NJDEP's solution for receiving ambient water quality data collected by multiple organizations. Data submitted to WQDE is sent to USEPA and then to the National Water Quality Monitoring Council's Water Quality Portal. Data from the Water Quality Portal is used by NJDEP to develop NJ's Integrated Water Quality Assessment Report.

Step Three: Submit Data
Once you are in WQDE, you may create projects, monitoring locations and submit results.
The Water Quality Exchange (WQX) is USEPA’s framework that makes it easier for States, Tribes, and others to submit and share water quality monitoring data over the Internet. States, Tribes and other organizations can now submit data directly to the publicly-accessible STORET Data Warehouse using the WQX framework.
WQX Web is a web-based application designed to assist smaller organizations with submitting data via WQX. WQX Web is a tool that converts text files (such as comma or tab-delimited files) into a valid WQX submission file (based on the WQX schema). WQX Web also interacts with the Central Data Exchange (CDX), which is the EPA's portal through which all environmental data is expected to flow. WQX Web is also a data conversion and validation tool, providing support for user-defined file formats and user-defined translations to WQX-compliant values for items like Characteristics, Taxonomic Names, Units of Measure, etc.
A WQX Web template is available to assist organizations with formatting their data for upload to WQX Web. Please see the WQX Web Resources page to access the template.
Data submitted to WQX is used by NJDEP to develop New Jersey’s Integrated Water Quality Assessment Report.
