Three short animations showing how environmental consultants identify a soil contamination issue, present a remediation solution, and demonstrate the results.
2. The Problem
The following animation details the results of a soil
investigation, performed in order to determine the
amount of contamination in soil from a suspected
perchloroethylene (PCE) spill.
For years PCE was commonly used as a dry cleaning
solvent, however, its use has been phased out recently
because of its toxicity to humans.
The investigation succeeded in determining the sources of
the PCE spills, as well as quantifying the amount of PCE
that was present in the subsurface.
3. The Solution
The following animation details the technology used to remediate
the subsurface PCE soil contamination – a Soil Vapor Extraction
(SVE) system.
SVE systems operate by pulling a vacuum in the subsurface soils,
which extracts the contamination in the vapor phase.
SVE systems are viable remediation solutions in porous (sand or
gravel) type soils.
4. The Results
The following animation details the results of the Soil Vapor
Extraction remediation system.
Subsurface PCE vapor readings and vacuum readings were
collected on a weekly basis and modeled.
The right panel depicts PCE vapors in the subsurface, and the
left panel depicts the amount of vacuum present in the
subsurface.
