Former Quarry and Haulage Yard in Northampton: Bioremediation of soils followed by treatment of hydrocarbon impacted groundwater.
Client : National House Builder
Value : £250,000 contracting costs

T&P Regeneration were appointed to provide the initial design, liaise with the regulators to obtain all necessary approvals, manage the tender process and oversee/validate the subsequent remedial works.
The site, which was adjacent to a river, was shown to contain in the region of 13,000m3 of hydrocarbon impacted soils and this had also resulted in groundwater contamination beneath the site.
Based on an economic evaluation it was shown that bioremediation of the soils was the most cost effective solution.
The general scope of the works undertaken by T&P included:
- Review of the existing third party site investigation data followed by an intrusive supplementary investigation to provide necessary information to model the site conditions;
-
Liaison with the Local Authority and Environment Agency to agree the most suitable remedial strategy;
- Production of tender documents and management of the tendering process and assessment of submissions;
- Supervision and management of the remedial works;
- Production of Validation Reports to obtain regulatory “sign off” for the works
