The probe is driven into the ground by a hammer. It is then collected inside the core-barrel chamber within the lower half of the probe. The probe is lifted 4 inches, opening a hidden compartment that channels the groundwater into a water canister through Teflon straws located in the grooved edges running along the length of the core-barrel. The water canister is closed by back pressurization, which prevents the escape of Volatile Organic Compounds (VOC) while the probe is removed from the exploratory borehole. At the surface the soil core and groundwater sample can be easily removed from the SimulProbe for shipment to a laboratory.
