"Providing Cradle-to-Grave Environmental Services"
How can the Army Corps of Engineers most effectively achieve turnkey
environmental remediation services throughout a large geographical region
in the Midwestern United States?
That has been the goal of a ten-year Total Environmental Restoration
Contract (TERC) for MWH merger partner Montgomery Watson. On behalf of
the Army Corps of Engineers, Louisville District, MWH has performed a
wide array of environmental remediation services. These include:
- Remedial investigations/feasibility studies/design;
- Human health and ecological risk assessments;
- Waste characterization and confirmatory sampling and analysis;
- Low level radiological waste investigations and removal;
- Hazardous waste excavation, transportation and disposal;
- Unexploded ordnance investigation and clearance;
- Community relations support; and
- Modeling and database services.
MWH has executed more than US $60 million of services on the TERC contract,
which has a ceiling of $300 million. To date, our specialists have maintained
a superior safety record, recording more than 200,000 hours with no lost
time incidents and no major OSHA reportable incidents.
Complex Projects
Over the years, MWH has assisted with a number of projects involving
multiple stakeholders and politically sensitive issues. These were handled
with minimal government oversight.
- At Marion-Scioto FUDS Site in Ohio, MWH performed a fast-track remedial
investigation on 78-acres of school grounds, which were the subject
of intense public scrutiny due to suspected low-level radioactive contamination.
Our team performed a Class I MARSSIM-type surface radiation survey;
soil gas survey; and time sensitive removal action of arsenic-contaminated
soil. This was all conducted during school vacation in response to enormous
public and political concern about the site's potential health risks
to the community.
- At Joliet Ammunition Plant in Illinois, MWH designed, constructed
and is operating the world's largest bioremediation facility for treating
explosives-contaminated soil. To design the facility, our staff conducted
an extensive search for the most cost-effective treatment methodologies.
MWH constructed the office facilities, decontamination facilities, soil
treatment and storage facilities, and all utilities associated with
the treatment process. To date, this treatment facility has saved the
US government $10-12 million.
- At NASA Plum Brook Reactor Facility in Ohio, MWH is decontaminating
and dismantling the 27-acre nuclear facility, which includes a 60-megawatt
nuclear reactor and a 100-kilowatt mock-up reactor once used to study
radiation's effects on materials used in space flight. Before MWH demolishes
the structure, it will remove a variety of radioactive and hazardous
wastes, including tritium, cobalt-60, strontium-90, cesium-137, asbestos,
lead-based paint and PCBs. The project is expected to come in two years
ahead of schedule, at significant cost savings to the government
