An official website of the United States government.

Due to a lapse in appropriations, EPA websites will not be regularly updated. In the event of an environmental emergency imminently threatening the safety of human life or where necessary to protect certain property, the EPA website will be updated with appropriate information. Please note that all information on the EPA website may not be up to date, and transactions and inquiries submitted to the EPA website may not be processed or responded to until appropriations are enacted.

We've made some changes to EPA.gov. If the information you are looking for is not here, you may be able to find it on the EPA Web Archive or the January 19, 2017 Web Snapshot.

WQX Web Application Programming Interface

EPA’s Water Quality eXchange team, the Chesapeake Bay Program, and EPA Contractor Gold Systems have developed, tested, and utilized a new way to submit data to WQX and the Water Quality Portal. Until very recently the only two methods to publish your data via WQX were to set up an automated node to node communication via EPA’s Exchange Network or to manually upload your data using the WQX Web user interface.

You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.
