Heavy Duty Gas Vapor Probe Kits 209
Rapid access to sampling points may be achieved with the AMS Flighted Auger when used with a heavy-duty electric drill. If you already have a drill, the Flighted Auger Kit can be purchased without the drill. All kits include an Extendible Tile Probe and the Slide Hammer. We recommend that these be used to prepare a hole before inserting either a GVP Point or the Retract-A-Tip. The kits may also be used to obtain samples of shallow groundwater. Use the optional screens for the points and Retract-A-Tip to prevent blockage.

Product Description
DESCRIPTION:
The Gas Vapor Probe System is the finest system available today for environmental assessment and monitoring. It is available as a series of kits from a Basic Kit without a drill to a Heavy Duty Kit that also includes AMS Flighted Augers. 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.
BENEFITS AND FEATURES:
The AMS Gas Vapor Probe has been designed specifically for placement of devices used to recover soil gas samples. The GVP kit may also be used for collection of soil and groundwater samples when used with accessory screens that are sold separately.
USE:
The site should be surveyed for the presence of underground utilities, pipelines, underground tanks and piping, as well as other structures or objects. The position of underground objects should be flagged and/or marked to local protocols.
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 Flouropolymer 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 rotorary hammer drill. Once the first extension has been lowered or driven into the ground, place at clamp (not supplied) at ground level to stabilize 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.
