Soil Vapour Implants can be used for permanent or temporary installations. They can be used for soil gas sampling, air sparging, and even groundwater sampling. They are an accurate and economical way to sample soil vapour.
These popular mesh implants come with a barb on top to connect to 1/4” Teflon® tubing. A threaded bottom connection allows connection to a weight to pull the implant down during installation.
The implant mesh allows easy passage of the soil vapours to pass in from the target zone into the tubing. The barb allows leak free and tool-less connection of the Teflon® or other similar tubing up to the surface. A range of surface connection fittings are available to provide flexibility to various connection methods at the surface.
Installation involves drilling or augering a hole down to the target zone, placing in an implant with connected tubing. Then backfilling around the implant with sand and gravel pack across the target zone. Finally filling back in with soil and or bentonite to make a seal from the surface. The top end of the tubing is where the soil vapour sample is drawn from. When not in use keep this capped.

Due to the coiled Teflon® tubing acting like a spring, it can bind on the sides of the bore. For shallow installations of a few metres, a weight may not be necessary. For deeper installations a weight is recommended to pull the implant down to the bottom.
The Nondo Mini monitoring well cover is our budget bolt-down, flush mounted well cover. It is designed to be used for monitoring wells or for soil vapour installations. With the bolts outside the inner working space, the Nondo Mini gives you maximum internal room for such a small cover. Features:
King Stuff is an all-weather product hydrocarbon free grease designed for monitoring well installs, and other environmentally sensitive drilling applications requiring a petroleum hydrocarbon-free product. King Stuff has a temperature range of -40°C to 260°C with a flash point of 226.7°C.
