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.
