NO-PURGE GROUND WATER SAMPLING:
Is Now the Time to Curb the Urge to Purge?
Discover the advantages and latest advances about no-purge sampling. Learn why there is a growing interest in no-purge sampling and it's contrasting procedures to traditional groundwater sampling methods. Each of the common ground water sampling methods, volume purging, low flow sampling and no-purge sampling will be described and the differences between the sampling methods will be examined.
The variations of no-purge sampling devices will be introduced with discussion of how they work and advantages and limitations of each class of sampler. Finally, an in depth discussion of the advantages and limitations of no-purge sampling and supporting case histories will be presented to help you determine what options may work best for your project site.
What is no-purge (passive) ground water sampling and why has it become the fastest growing ground water sampling method?
- The history and evolution of ground water sampling methods.
- Why well purging began.
- Examination of the different sampling methods and their effect on samples.
- Why different sampling methods sometimes yield different results.
- Types of no-purge sampling devices and how they work.

He is the founder and president of GeoInsight; a company established in 1991 that focused on the development and production of innovative direct-push equipment. In 1996, he received the National Groundwater Association Technology Award for major contributions to the groundwater industry related to direct push groundwater sampling. In the summer of 1999, Mr. Cordry began development of the HydraSleeve no-purge (passive) groundwater sampler and has since received two patents for the invention. In total he holds ten patents, including those covering the HydroPunch I, HydroPunch II and the HydraSleeve.
Prior to starting GeoInsight, Mr. Cordry spent 10 years as an environmental consultant, serving as project manager/senior hydrogeologist, managing site assessments throughout the United States.
