Trends in Groundwater Sampling: A Comparison of Groundwater Sampling Methods
December 2, 2020
ABOUT THIS WEBINAR:
Purging and sampling methods and protocols have evolved over the past thirty years, from 3 – 5 well volume purging to low-flow purging and sampling to "no-purge" and passive sampling approaches. This webinar provides an overview of these various groundwater sampling methods and technologies and examines the benefits and limitations of each. The presentation includes guidance on the suitability of various purging and sampling methods for different hydrogeologic settings and monitoring program types.
PRESENTATION TOPICS WILL INCLUDE:
- History of traditional purging methods
- Problems with the traditional methods
- Purging evolution: low-flow purging and sampling
- Low-flow samples: what do they represent?
- Advantages of low-flow purging and sampling
- Passive and No-Purge sampling methods and devices
- Passive and No-Purge: advantages and limitations
- Comparison of LFPS and Passive/No-Purge methods
- Monitoring well bias and limitations
- Multi-level sampling systems – advantages and limitations
The 40-minute presentation will be followed by a 15-minute Q&A session to answer your questions about PFAS sampling practices, materials options and more.
WHO SHOULD ATTEND?
- Facility Environmental Managers
- Environmental Specialists
- Plant Utility Workers
- Engineering Firms
- Operating Firms
- Consultants and Regulators
David Kaminski is Senior Vice President of QED Environmental Systems and a frequent presenter on groundwater sampling technology to organizations, universities, and regulatory agencies worldwide. He has been awarded four U.S. patents for developing new devices and methods for groundwater sampling applications and is an instructor at the Princeton Groundwater Pollution & Hydrology course (www.princeton-groundwater.com).
Over the past 30, years he has published several papers on groundwater sampling practices and sampling system design and has presented these topics at over 100 conferences, seminars and field courses. Now, he will be sharing his considerable knowledge in the field of groundwater monitoring and sampling with all who attend the webinar.
