Porosity used for bentonite: 0.35
Purge Time = Total PV/Purge flow rate Total Pack volume equals sum of sand and bentonite pack volumes Purge Volume: Based on the 7/15/15 DTSC Soil Gas Advisory, remove 3 purge volumes prior to each sample collection (purge times shown above).

A probe tip is set in a sand pack; the probe tip is attached to tubing that leads to the surface. The tubing ends are sealed with gas-tight plugs.
Wells are capped with concrete (removed prior to sampling). After sampling, the concrete cap is re-installed (charcoal-colored dye added).

1) Tracer Gas Shroud for Helium (Entech part SG-He-Shroud) includes shroud-to-surface sealing ring 2) Helium Analyzer, 0.1-100% (Entech-He-Analyzer)
3) 200 ml/min sample train: 3-way valve, magnetic latch, down-hole gauge for measuring vacuum in soil gas, and a separate second gauge measuring the sampling train vacuum (Entech SG-CHAM-TC-200-S)
4) Compressed helium with regulator
(5) Shut-In Test
Prior to each sample collection, the sampling train is isolated from the soil gas probe via a shut-off valve.
Next, the sampling train pressured is lowered to a vacuum of 100 inches of water. This vaccum is held for a minimum of one minute before sampling proceeds.
