Supervision of Contamination Remediation of Former Petrol Filling Station

Ruddlesden geotechnical recently supervised the contamination remediation works for residential development of a former petrol filling station site in Exeter.

Ruddlesden supervised the excavation of the underground fuel storage tanks, pipelines and interceptors, as well as grossly contaminated soils. Validation testing of the resultant excavations was subsequently undertaken, to demonstrate that no unacceptable levels of contamination remained in the ground.

Groundwater quality monitoring in borehole installations was also undertaken before, during and after the remedial works, to assess the risks to controlled waters and a betterment of groundwater quality.

Close liaison throughout the works with the local authority and Environment Agency, ensured that the regulators were satisfied with the works and all the relevant planning conditions were discharged.
