Site Overview
The site was the former engineering works off Moor Lane Mansfield, Nottinghamshire
At the time, the site comprised of the works and office buildings, car parking and several of oil and chemical storage tanks.
As a consequence of the site history and activities undertaken, part of the site was impacted with Total Petroleum Hydrocarbon (TPH) contamination.
The site was developed for residential end usage. The development comprised of a mixture of traditional two storey houses and flats with associated residential gardens, managed landscaping, car parking and access roads.
Objective
The remediation strategy for the Mansfield site was designed to address the on-site source contamination and associated pathways with the intention of protecting both human health and groundwater receptors.
Of significant regard was the underlying Lower Mottled Sandstone and Lower Magnesian Limestone beds, both of which are classified as major aquifers of high vulnerability.
Methodology
Envirotreat employed an ex-situ soil mixing remediation strategy for the treatment of over 2,475m3 of TPH contaminated soils.
The works were undertaken over a 6 week period. The works were undertaken under an Environmnetal Permit Mobile Process Licence were treated soils were fully recovered to enable reuse onsite.
The treated soils were validated by leachate testing and comparison to the agreed Remediation Target Criteria
