Foundry and Industrial Site, Sheffield
The site was to be redeveloped as a main dealership close to the city centre.
Historically the site had had several uses and various contaminants particularly heavy metals were present within the soils.
The main problem was the heavy fuel oils in the soils and groundwater, particularly the free phase which had recorded thickness up to 450mm.
An insitu treatment system was installed as part of the redevelopment works. The system was completed buried and continued to operate once the site was complete and operational as a car dealership.
