This Soil Vapor Probe System is the finest system available today for environmental assessment and monitoring. Used for collecting samples of soil gas at shallow depths.Tips are offered in a dedicated tip or a retract-a-tip, which is removable.
Use the electric drill with 1 1/2″ Concrete Bit to cut a hole in the pavement if necessary, prior to using the tile probe. Once the pilot hole has been made, proceed sampling using the GVP points. Following the determination of sample collection depth, cut a length of Fluoropolymer tubing slightly longer than collection depth. This extra length is to aid in the ease of sampling with tip installed. Attach one end to the barbed nipple on the selected sampling tip. Assemble from the sampling tip up. Place the assembled sampler, comprising tip assembly, extension, and extension drive adapter tip downward into the hole prepared by the Tile Probe. Certain soil conditions may allow for the assembled piece to be driven directly into the soil itself. Driving may be accomplished via AMS Slide Hammer, or electric rotary hammer drill. Once the first extension has been lowered or driven into the ground, place at clamp (not supplied) at ground level to stabilise it. Lift the driving device off the probe assembly, loosen and remove extension drive adapter from the extension and teflon tubing. Pass the tubing through another GVP extension with the coupling down. Remove ground clamp, and continue to drive and add extensions until sampling point(s) have been reached.
