Prevent cross contamination with a cased access hole.
The portable AMS Hollowstem auger kit provides the tools needed to reach a 6′ depth. The augers cut a 3″ diameter hole and have an ID of 1 1/8″, making them suitable for soil, soil gas and groundwater sampling through a cased hole. A special Hollowstem soil probe, 7/8″ OD by 24″ long with slide hammer is included to allow collection of a soil sample through the auger. The AMS gas vapor probes may bae used through these augers telescopically. Bailers up to 1″ diameter may be used to collect groundwater samples.
