Phase III Environmental Remediation
Whether environmental remediation is performed to maximize the value of
commercial real estate, or to meet minimum regulatory requirements, BEI
has
the skills to remediate soil and groundwater to the necessary cleanup
objectives.
Free Product Recovery
The presence of free product is usually detected during the removal of
an
underground storage tank or during the associated site assessment. Free
product removal is required by law.
BEI employs multiple methods of
free
product recovery, including the use of vacuum and skimmer pumps and
surfactants. The chosen method often depends on site-specific
limitations.
Groundwater Remediation
BEI has designed, installed and operated several types of groundwater
remediation systems from groundwater pump and treat systems to shallow
tray
air strippers. It is important to quickly establish a cone of
depression on
the water table to hydraulically control the spread of groundwater
contamination.
A dual-phase extraction system not only remediates
contaminated groundwater but, when properly designed, also remediates
contaminated soil. The driving force behind a successful dual-phase
extraction system is a high powered vacuum pump.
Soil Remediation
In addition to soil vapor extraction (SVE) systems, BEI has used
conventional methods for the remediation of soil, excavation & disposal.
In
northern Illinois, based on the tight clay soils, excavation & disposal
is
the fastest and most efficient way of meeting soil remediation
objectives.
During the excavation & disposal of contaminated soil, it is necessarily important to closely document the transportation and disposal of
contaminated soil in accordance with the Resource Conservation and
Recovery
Act (RCRA).
For deep excavations, earth retention systems (sheetpiling)
are
required to prevent the collapse of adjacent soils.
