The presence of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in food, water, and consumer products is a persistent and growing concern due to their potentially harmful effects on health. With extremely strong carbon-fluorine bonds, PFAS do not easily biodegrade and are therefore known as “forever chemicals.” Thousands of Legacy and GenX compounds are in circulation, many of which are highly soluble in water and are known to bio-accumulate—in a manner similar to mercury—in living organisms including fish, animals, and humans. Research into PFAS levels in all forms of water resources is ongoing. The PFAS regulatory environment, which is expected to increasingly impact the operators of water and wastewater systems, is evolving. Detection of PFAS at the parts-per-trillion level is a further challenge, with a variety of water-sampling errors that industry professionals must avoid.
In this webinar, Steve McManus, Senior Product Support Specialist, Teledyne ISCO, describes the most important PFAS sampling pitfalls and how to avoid them.
- What are PFAS, where do they come from, where are they going, and why?
- The evolution of regional, state, and federal rules for PFAS
- WWTPs are point sources for PFAS pollution.1
- Remediation options are severely limited and are still being researched
- The importance of staying well ahead of the PFAS regulatory curve
- Sampler options for various environments
- Known sources of sample contamination and how to avoid them
- Sampler programming considerations
- Ensuring your samples will always meet your analytical lab’s requirements
From this 45-minute presentation plus interactive Q&A session, attendees will be brought fully up-to-date on the current PFAS landscape, how it is evolving, and how to develop highly effective sampling strategies for a variety of challenging environments. Learn also how to access Teledyne ISCO’s PFAS experts at any time to assist with sampler selection, installation, operation, and maintenance.
How to Measure Flow in Rivers & Wide Channels (Re-Run)
Date: Tuesday, July 27, 2021
Time(s): 7:00 a.m. CDT; 1:00 p.m. CDT, 8:00 p.m. CDT
Measuring flow rates in large open channels and rivers is a challenging task requiring the right set of instruments properly calibrated and configured, and coupled with fully validated data-interpretation and calculation methods. Obtaining highly accurate readings for level, velocity, and flow is critical to programs involving flood control, irrigation, hydroelectric power, environmental protection, wastewater management, and more.
In this intermediate-to-advanced webinar Teledyne ISCO’s flow measurement experts discuss current best practices for obtaining accurate and reliable flow rate data in environments where traditional small-channel and/or closed-channel methods are not suitable.
- Level and velocity measurement technologies
- Ultrasonic versus radar
- Sensor range considerations
- The impact of channel shape on instrument selection and setup
- Expected accuracy of open-channel flow-measurement systems
- Data retrieval options
- Data validation and flow rate calculations
From this 45-minute presentation plus Q&A session, attendees will be better able to assess large open channel installations to identify important challenges and select the most appropriate measurement instruments and calculation methods. Attendees will also learn how to access Teledyne ISCO’s flow measurement experts at any time for help with system installation, configuration, operation, and data validation.
