NO-PURGE GROUND WATER SAMPLING: with Technical and Regulatory Updates for Ground Water Sampling Trends

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.

Recent regulatory changes and technical advances have affected the trends of no-purge sampling and the equipment that is used for ground water sampling.

Register now and learn up-to-date ground water sampling methods including volume purging, low flow sampling and no-purge sampling. A comparative contrast between the sampling methods will be examined so you can compare what works best for your site.

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?

Highlights:

• 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.
• Advantages of no-purge sampling with case studies.
• Limitations of no-purge sampling.
• Summary and questions.

What you will learn:

• Will learn what no-purge ground water sampling is.
• Understand why many sites are switching to no-purge sampling.
• Learn the differences between volume purging, low-flow and no-purge sampling and decide which is most suitable for their sampling requirements.
• Learn about the three different classifications of no-purge ground water samplers
