Monitoring: Water Quality

Administered by the Utah Division of Water Quality


As Utah DWQ continues to import data into AWQMS, new processes are being developed for Quality Assurance and Quality Control. AWQMS users are encouraged to review their data sets thoroughly and understand the data limitations. While the initial priorities have been populating the database and establishing a routine update schedule, our review of the database implementation and data integrity will continue to be a focal point. Efforts to standardize data migrated from STORET into AWQMS will also be an ongoing effort. Users should review information provided on this Web site to help interpret their data findings. Please contact Utah DWQ if you have questions.

Storet logoBackground

Historically, the Division of Water Quality has utilized a STORET database for management of its water quality and biological data, and field parameters. In the fall of 2009, EPA discontinued support for data submissions via the distributed STORET database.

EPA has since promoted the development of Exchange Network Nodes or Node Clients as part of the National Environmental Information Exchange Network for states to submit a wide range of environmental data to national repositories.

The Utah DWQ, in conjunction with the Exchange Network, has developed a data storage solution with the WQX schema known as the Ambient Water Quality Management System (AWQMS).
