Environmental Drilling

In addition to performing site investigations with the UVOST, Hammer Environmental Services can perform more traditional environmental drilling services.  Hammer Environmental employs a Geoprobe™ 6610DT direct-push tract vehicle. Direct-push drilling uses percussion power to essentially ‘hammer’ sampling equipment (Macro-Core samplers) into the subsurface to extract soil for laboratory analysis. Soil retrieved can be analyzed for any number of contaminants, for any number of soil analysis methods.

Although direct-push has limits in respect to power, and consequently sample depths, the ability of the tract vehicle to get into and sample in tight and hard-to-reach locations make it an attractive tool. Direct-push is also far quicker and easier to obtain multiple soil samples from shallow depths. The Geoprobe™ 6610DT can also install temporary and permanent groundwater monitoring wells. The subsurface is bore with 3.25-in probe rods (DT325 system) and 1.5-in inner diameter pre-packed well screens are lowered and secured in-place with PVC risers. Wells can be temporarily developed, sampled, and then removed or permanently developed for multiple groundwater sampling events.

Hammer Environmental also has a much smaller Geoprobe™ 540MT direct-push drill unit (photo pending).  Follow the link below for more information regarding the 540MT;

The 540MT is an extremely portable drill unit, weighing only 900+ lbs.  With the additional hydraulic power unit, hoses and tooling, the 540MT can squeeze in at under 1,700lbs for small aircraft transportation.  This unit is advertised as 20 to 25-ft of subsurface penetration; translated into Alaskan as 10 to 12-ft.  But, for hard to get to remote areas with shallow groundwater, this unit may be just perfect.
