The site on Coventry Road historically formed part of an engineering and locomotive maintenance works.
A site investigation identified the presence of hydrocarbon contamination in the area of the site associated with the former engineering and locomotive maintenance works / plant hire depot.
Total petroleum hydrocarbon contamination in both soils (104,000 mg/kg) and groundwater (3,400 mg/l)
There was an identified risk to both potential human health and groundwater receptors – the prime groundwater receptor being the nearby Hatchford Brook.
The preferred remediation option was E-Clay stabilisation of the grossly impacted soils and an E-Clay Permeable Reactive Barrier to address the offsite migration of groundwater, providing an integrated remediation stratety for the site.
