Having recently completed in-situ thermal clean-up operations at Area 1 of the Velsicol superfund site in St Louis, Michigan, Jacobs has been awarded a $25m follow-on project by the US EPA.
In the initial project Jacobs removed chlorinated solvents, specialty chemicals, oils and petroleum products from a one-acre zone of the site. The follow-up will see Jacobs install subsurface components and operate a thermal treatment system – a remediation technology which utilises heat to remove organic contaminants from soil – across the three acres of Area 2 at the site.
Jacobs global environmental solutions senior VP/general manager, Jan Walstrom, said: "We are proud to support the EPA and the local community with the clean-up of this complex site. The work on Area 2 will continue to build on our shared successes with the safe delivery of innovative remediation design, construction and operations."
Jacobs has been working with the EPA for two decades on the clean-up strategy, design and implementation at the Velsicol superfund site. The firm has also completed the residential soil clean-up in nearby neighbourhoods, including the excavation and disposal of over 40,000 tons of contaminated soil.
The Velsicol Chemical Corp (formerly Michigan Chemical Corp) produced various chemical compounds and products at its 54-acre main plant from 1936 to 1978.
