If you need to gather samples beneath a concrete pad, this carbide bit can drill a hole large enough to allow a ESP Plus Sampling Tube to pass through.
Developed for soil dissipation studies, but can be used like any of our sampling tubes. Sampling tube fills a plastic liner 2 inches in diameter by 6 inches long. Best for shallow sampling applications, this tube fits most of our JMC sampling devices, but may require an adapter.
The JMC Environmental Fate Sampler takes a 6 inch diameter by 2 inch deep sample. Compatible with the JMC Environmentalist Sub-Soil Probe or any hydraulic soil probe, it maximizes recovery of surface applied chemicals on day zero and greatly reduces surface contamination risk to subsequent samples.
In some situations, it may be expedient to plant several 2 inch diameter casings in the ground before returning to sample through each one. That is why we sell separate casings for the JMC 2 by 6 inch Concentric Sampling Tube.
Remember: This is the casing only. You should already have a Concentric Sampling Tube.
