Former Petrol Station – Ground Investigation

The LK Group was asked to complete a Preliminary Risk Assessment (PRA) and Phase 2 geo-environmental site investigation for a housing development in Salford.
The Project
The PRA identified the site as a former petrol filling station, which informed the design of the Phase 2 site investigation comprising boreholes and trial pit excavations. Significant hydrocarbon contamination was identified in soil and groundwater.
THE SOLUTION
In consultation with the Local Authority Contaminated Land Officer, we designed a groundwater collection system to allow off-site disposal of the shallow groundwater. Due to tight timeframes and to reduce impacts on the development program, it was agreed that the source of the contamination would be removed via the excavation of contaminated soil for off-site disposal. We completed a delineation investigation to further assess the extent of shallow soil contamination, ensuring no uncontaminated material was removed from the site, thus minimising project costs.
THE BENEFIT
Our rapid response significantly reduced the extent of groundwater contamination, and our delineation works minimised the volume of contaminated soils removed from the site. This resulted in a £100,000 reduction of additional potential costs for our client. We consulted with Regulators throughout the project to ensure compliance for ultimate project sign-off and no delay to the program of works for the development.
