Geoprobe Services
The ability to delineate subsurface chemical constituents quickly
and cost-effectively is a challenge for property owners faced
with environmental liability issues. We meet these challenges
using state-of-the-art technologies such as the Geoprobe©
mobile laboratory. The Geoprobe allows our staff to collect soil
vapor, soil, and groundwater samples from varying underground
depths and soil conditions. The Geoprobe and analytical equipment
housed within are a self-contained unit, therefore, we can mobilize
to different areas within a site rapidly and access areas that
a conventional drilling rig cannot.
Capabilities
Summit's Geoprobe is equipped with a laboratory-quality gas chromatograph
and purge-and-trap sample concentrator that are interfaced with
an on-board computer. With these analytical tools available in
the field, we provide real-time analysis for petroleum products
and other volatile organic compounds. Applications for the Geoprobe
include:
- On-site analysis of volatile hydrocarbons in surface water,
soil, and air;
- Delineation of subsurface petroleum hydrocarbon plumes using
PID and/or FID detection capabilities;
- Delineation of subsurface plumes containing chlorinated and
other volatile hydrocarbons using ECD detection capabilities;
- Landfill gas investigations;
- Characterization of chemical constituents in the unsaturated
zone using soil vapor assessments;
- Completion of utility assessments to address the potential
for off-site migration of chemical constituents;
- Soil vapor extraction and air sparging testing and evaluation;
- Mobilization to remote and difficult-access locations;
- On-the-fly conversion to Bobcat for tight access situations;
- Continuous Electric Conductivity vertical logging
The Geoprobe sampling and analytical unit allows us to obtain
information about chemical constituents in the subsurface quickly
and, in many situations, more cost-effectively than if samples
were sent to an off-site laboratory for chemical analysis. Elimination
of these off-site analytical delays can expedite characterization
of the site. In many cases, this results in an optimized expenditure
for site characterization and a basis for developing remedial
alternatives.
