Heating Oil Spill Remediation Case Study - Cotswolds

In 2017 OEE were appointed under a domestic insurance policy to remediate a kerosene spill against the gable end of a listed Cotswold Farmhouse. Challenges of heavily contaminated shallow groundwater and soils below the property were overcome using a combination of ex-situ and in-situ remediation techniques.

OEE were able to rapidly mobilise a groundwater pump and treat system to recover kerosene from a stone-built water well and remediate the shallow groundwater. Window sampling was utilised to delineate the plume extent and inform the remediation strategy.

Source contamination was addressed via a combination of targeted physical excavation, soil vapour extraction (SVE) and in-situ chemical oxidation (ISCO). This innovative approach proved to be extremely effective in restoring residential amenity to this Grade II Listed farmhouse with no discernible foundational structure.

Verification was achieved through soil, groundwater and internal ambient air sampling, which confirmed the risks to human health, building structures and controlled waters had been reduced to an acceptable level following the works.

The remediation strategy provided the client with a cost effective and un-intrusive  means  of addressing the contamination and was delivered by OEE within schedule and budget, prompting excellent feedback from the homeowner.
