EMI has managed investigative, design, construction, and operation and
maintenance projects that encompass a wide range of soil and groundwater
conditions. Our project management experience includes multi-million dollar
projects with significant public exposure and regulatory oversight. We
have worked in numerous states across the United States. When managing
site closures we always look to identify future site uses that are consistent
with effective remedial strategies. Please contact us for more detailed
information on any of our project highlights listed below.
Developed a detailed understanding of soil conditions at a site in California
that was so significant that a $50 million U.S. EPA selected soil treatment
remedy was replaced with a $12 million containment remedy.
Developed an approach at a site in California that suspended
operation of a ground water extraction and treatment system after only
thirty months of operation. Our data demonstrated that natural attenuation
was reducing the concentrations of constituents of concern towards the
Managed the analysis of groundwater conditions at a site in Michigan
so that natural attenuation replaced the ROD selected pump and treat
Managed the analysis of groundwater conditions at a site in Illinois
to limit the extent and duration of groundwater extraction and treatment
based on technical impracticability.
Led post-ROD remedy negotiations at a site in New York that thwarted
an attempt by the U.S. EPA to expand leachate collection requirements
into groundwater extraction and treatment.
Managed data evaluation at a site in Indiana that resulted in
suspension of off-gas treatment system operation, a major contributor
to the operating costs at the site.
Worked with land use planning firms to identify specific future
uses that are compatible with effective remedial options.
Used risk-based approaches to develop cleanup levels. For example,
EMI has negotiated cleanup levels based on 10-4 exposure point risks
and 10-5 exposure domain risks.
