Letter of recommendation from our client
Problem to solve:
The site was a previous cokeswork, which will be reaffected into small business area. The cokesworks were owned and operated by USINOR (Group ARCELOR), and the company decided to clean-up the site before resuing it through the local community. The contaminated soils held average PAH concentrations in excess of 12,000 mg/kg (with max concentrations up to 18,000 mg/kg).
Cleaning objective:
Clean-up targets for clean soil were set at 20 mg/kg total PAH (16 EPA).
Deep Green solution:
The project was done with the mobile DRAGON 35 unit, in a hot plant set-up. Stack tests were regularly performed and were supervised by the DRIRE and an external independant consultant working directly for the client (Arcelor). The unit was equipped with Continuous Emissions Monitoring systems.
Resultst:
All clean soils were under the clean-up target after treatment.
