Continuous Water-Quality Records Refresher
Monday July 20, 2026 1:00pm - 5:00pm CDT
The USGS maintains a large network of real-time continuous water-quality instruments to assess conditions in surface and groundwater. Throughout the country, there are over 2,500 sites where temperature, specific conductance, pH, dissolved oxygen, and turbidity are monitored and data are publicly available. This refresher presents concepts and procedures for record computation outlined in Techniques and Methods Report Book 1, Section D3 titled "Guidelines and Standard Procedures of Continuous Water-Quality Monitors Station Operation, Record Computation and Data Reporting." USGS Scientists that are involved in the collection and processing of continuous water-quality monitoring data and interested in better understanding continuous water-quality monitoring records computation are encouraged to attend. This is not intended to replace QW2298, but to offer staff an opportunity to get hands-on training and assistance in water-quality records.

Water You Waiting For? Dive Into the Latest Continuous Water‑Quality Updates
Tuesday July 21, 2026 3:00pm - 3:50pm CDT
The USGS Continuous Water-Quality community maintains a large network of real-time instruments. Throughout the country, the USGS is collecting over 6,000 continuous water-quality datasets at over 2,500 sites and measuring more than 8 water-quality parameters (temperature, specific conductance, pH, dissolved oxygen, turbidity, nitrate, chlorophyll, and Fluorescent Dissolved Organic Matter (fDOM)). Discover what CWQ resources are available for staff, who to contact with questions or suggestions, and what efforts are in progress.

Continuous Water-Quality Community Networking & Collaboration Session
Tuesday July 21, 2026 4:00pm - 4:50pm CDT
Learn more about the USGS Continuous Water-Quality Community at this facilitated networking session. Meet your colleagues, make contacts, and discuss parameters and processes. Ever wish you had more time to ask peers about equipment or a challenge? Great ideas often come by having conversations with people about a shared problem or interest. During this session, employees will get the opportunity to share perspectives with a subset of peers working on the same topics.

The TurbTube: Turbidity standard reducing device.
Wednesday July 22, 2026 3:30pm - 4:20pm CDT
Follow along on the story of development and testing of the TurbTube. From its early days as a submission to the Innovation Depot, through testing, and along in to the Open File Report process. Ask questions of one of the original submitters, Ernie McCoy, and the designer of the current tube, Bryce Redinger.

Continuous Water-Quality Data Corrections: Key Considerations
Thursday July 23, 2026 8:30am - 9:20am CDT
Continuous water-quality data need careful review and often require drift or fouling corrections to ensure accuracy. This session explains when and how to correct records, describes manual and automatic methods in Aquarius Time Series, and discusses percent versus multi-point corrections. The session also addresses data censoring. Participants will examine how to apply corrections for various continuous water-quality parameters and field conditions.
