First, a rod is hammered into the soil to make a cylindrical hole. The orange part at the top of the rod is a weight that is slid up and down to hammer the rod into the ground.

When this is the case, this allows for a more effective placement of monitor wells.

No publisher Robin Maiorisi 2011-08-26T13:25:26Z Image http://www.tceq.texas.gov/remediation/superfund/photo_gallery/kingsland/photo6 The hollow rod is in the ground, with the disposable syringe attached by disposable tubing. Several syringe-fulls of air are withdrawn before taking the sample, to make sure the sample is fresh soil gases.

No publisher Robin Maiorisi 2011-08-26T13:25:28Z Image http://www.tceq.texas.gov/remediation/superfund/photo_gallery/kingsland/photo9 A needle tip is screwed onto the syringe and the soil gas sample is injected into an airtight, rubber-capped vial. No publisher Robin Maiorisi 2011-08-26T13:25:00Z Image http://www.tceq.texas.gov/remediation/superfund/photo_gallery/kingsland/photo10 The vial is sent to a lab with very sensitive instruments to read the concentrations of contaminants in the gases.
