TITLE: Considerations For Use of Passive/No-Purge Groundwater Sampling
SPEAKER: Sandy Britt, PG, CHG, ProHydro, Inc.
DATE: March 12, 2015
TIME: 12:00PM EST
Passive groundwater sampling has increased as more practitioners recognize that the cost-saving approach is acceptable to regulators and data quality often meets or exceeds that of purge sampling. Low-flow sampling methods replaced bailer sampling due to data quality concerns of the “rough and tumble” bailer approach, but also to minimize waste footprint. No-purge sampling often reduces waste to zero and takes a fraction of the time that it takes to wait for purge parameter stability. Now, Department of Defense-supported studies are showing equivalent data quality too. A recent ASTM Standard D7929-14 provides a nationally-recognized standard for implementation.
Presenter Sanford (Sandy) Britt is a SERDP and ESTCP researcher with more than 10 years of experience studying passive well flow dynamics and passive sampling. Mr. Britt is also the developer of one of the passive sampling methods in the ASTM Standard. His research background gives him a unique perspective on how wells work and how those dynamics impact groundwater sampling results—whether sampling passively or by pumping. Mr. Britt will present background on the function of wells and why passive sampling often closely resembles pumped sampling results. He will also present research on passive sampling data comparisons and findings on data variability among methods. The presentation will provide attendees with an important basic understanding about the differences among sampling approaches, what specific devices are capable of, and their limitations. The presentation will be approximately 30-35 minutes, plus 10-15 minutes for Q&A.
