Environmental Drilling
Our mobile drilling equipment allows us to provide fast evaluations
of potentially contaminated sites. For drilling outdoors we use
an AMS 9100-SK rig, which is a hydraulically powered soil probe
unit. These direct push rigs are excellent tools for shallow soil,
soil-gas and water sampling. They can be used to collect either
depth specific or continuous samples. Continuous soil sampling is
accomplished using a small-diameter (1.5-inch inside diameter) macro-core
sampler, which collects 4-foot cores. Soil samples can be collected
from discrete intervals using a piston sampler. The depth limitation
of the AMS 9100-SK in normally consolidated soil ranges between
20 to 60 feet.
If drilling indoors
and collecting soil
samples, a Geoprobe®
open tube soil sampler
is used. For setting
sampling wells in
course grain sand
or gravels a portable
auger-based drill
rig can install up
to 2” wells.
When installing wells
on slopes or hillsides
a tripod mounted cathead
drill can provide
a stable angle to
drill to depths of
25 feet. All of our
drilling is done using
clean, non-contaminated
above and below ground
equipment in order
to provide accurate
sample integrity and
eliminate the possibility
of cross contamination
between sampling locations. |
