CB&I provides a variety of technical services and capabilities to federal and commercial clients, including the following:

  • Technical leadership
  • Technology applications (testing and laboratory services on hazardous, toxic and radioactive waste)
  • Management of U.S. Environmental Protection Agency (EPA) contract laboratories
  • Biotechnology development and applications
  • Bioreactor systems

CB&I has the ability and expertise to treat a wide range of inorganic, organic and biological contaminants, and we offer support from conceptual development through field implementation. We maintain two research and development laboratories for the evaluation, development and application of environmental remediation technologies. Additionally, we maintain a laboratory specializing in bioremediation technologies. Our laboratories also evaluate soils and sludges used in various thermal, stabilization, vitrification and bioremediation studies.

Our bioreactor systems are developed to treat recalcitrant pollutants including perchlorate, chlorinated solvents, methyl tertiary butyl ether and complex mixtures. These bioreactors include fluid bed bioreactors, membrane bioreactors and suspended carrier reactors. Biofilters and biotrickling filters are also developed and implemented for treating volatile organic compounds and noxious odors in air streams.

Through two current contracts, CB&I manages and conducts development work for the EPA's Office of Research and Development. Our work focuses on developing technologies related to water/waste water infrastructure support and on developing and enhancing analytical methods for contaminants in drinking water.

In a third contract with the EPA's Analytical Operations Center, CB&I provides quality assurance and technical support services principally focused on oversight of the Contract Lab Program as it relates to analysis performed on Superfund sites. Additionally, we manage on-site technical research support services for the EPA's National Risk Management Research Laboratory/Subsurface Protection and Remediation Division.

Bioaugmentation

CB&I's environmental protection and remediation services address complex environmental issues, such as the remediation of chlorinated solvents and the design of safe solid waste landfills. Our skilled scientists and engineers use a range of emerging and commercial technologies to solve issues involving hazardous, toxic and radioactive materials in all types of environmental media.

With more than a decade of bioaugmentation expertise, CB&I has performed bioaugmentation for chlorinated solvents, polychlorinated biphenyls, polycyclic aromatic hydrocarbons and methyl tertiary butyl ether. We also have successfully cultured and applied biodegradative bacteria to a wide array of ex situ systems.

We created a technology that treats chlorinated solvent contaminated aquifers. The culture contains Dehalococcoides sp. (DHC) bacteria that degrade highly chlorinated solvents to non-toxic ethene, making it well-suited for treating sites where remediation of perchloroethylene and trichloroethylene has stalled at these intermediates. This technology has been successfully applied at sites throughout the U.S., including some of the largest in situ bioaugmentation projects performed to date.
