As Principal Contractor John F Hunt is currently remediating a 26 acre site which previously accommodated heavy industrial usage, their legacy comprising underground storage tanks, pipelines, ducts, pits and soak-aways in addition to the residual process plant associated with a former oil terminal, printing ink and tar works. 

Significant pollution issues are present, including dense non-aqueous phase liquids (DNAPL) and contamination in the form of heavy and light hydrocarbons and asbestos in the soils.

Scope of Works

  • Demolition, remediation and enabling works for the redevelopment of this 26 acre former industrial site ready for commercial, retail and residential use.
  • Installation of a steam injection system to reduce the viscosity of DNAPL in order to enable the pollutant to be extracted from the underlying groundwater.  Steam facilitates the clean-up of the underlying aquifer and ensures regulatory compliance.
  • Solvent, hydrocarbon and PAH contamination is being treated on-site using a combination of complex sorting, bio-remediation and stabilisation techniques.
  • 40,000 litres of neat DNAPL has been removed to-date from the groundwater and over 30,000 m3 of soil is being treated using sustainable techniques—making the project one of the largest remediation schemes in the UK.
  • To satisfy planning conditions, site wide remediation and verification under the current Part IIA framework is required.
  • Ecological protection works (Japanese Knotweed and Giant Hogweed) are also required to satisfy planning conditions.
  • Following Local Authority and Environment Agency approval of a Remediation Strategy, earthworks and remediation began in January 2015 under a Materials Management Plan and Mobile Treatment Plant License.
  • The objective of the project is to remediate and enable the site to ensure it is suitable for future intended commercial/retail and residential use.
  • Due to the dilapidated state of the majority of structures, caused by vandalism & weather related damage, there were deleterious materials, including broken asbestos cement sheeting, pigeon droppings and fly tipped materials which necessitated specialist, controlled and monitored demolition and enabling.
  • On completion of the works, the site will meet site specific clean-up criteria associated with human health protection and groundwater resources.


  • Works are currently ongoing.
