Restoration Tech Transfer Series

13 July 2022 1400 Eastern, 1300 Central

ANNOUNCEMENT

 

Name of Briefer: Sandy Britt, PG, CHG, & David Kaminski (QED Environmental Systems)

 

Title of briefing: Passive Groundwater Sampling with the Snap Sampler: Background Studies, Efficacy Testing, And Economic Implications

 

Description: Passive groundwater sampling, including the Snap Sampler technology, has been shown in numerous studies over two decades to positively compare to more traditional purge and low flow purge sampling. Multiple studies show that whole water samplers, such as the Snap Sampler, can be used for any compound – increasing utility for users with wide ranges of contaminant types. The Snap Sampler, unlike some other no-purge devices, has never shown poor correspondence for any tested compound in any statistically significant subsets of wells.  This course of history is sensible given the design of groundwater monitoring wells is aimed at providing the best hydraulic communication between the screen zone of each well and its surrounding formation. Water moving in the formation also flows through well screen installed in that formation. Concern about "well effects" are largely inconsequential except for unusual hydrogeochemical environments.  Given the functionality of the method, economics becomes a driving factor for selection and use of such an approach.
