We have recently completed an incident response investigation of a domestic heating oil installation located at the centre of a residential accommodation block complex in southern England. The site overlies chalk and is located just 100m from a public drinking water supply borehole.
Following complaints of possible oil contamination issues from the residents we took samples of the underlying soils and audited the fuel installation. With only footpaths leading to the tank installation we used our Terrier drilling system – which can fit through a standard doorway – to install boreholes either side of the oil tank and take soil samples for rapid analysis in our UKAS laboratory. Fortunately no significant soil contamination had occurred and our recommended improvements to the installation are now underway. The entire project, from initial enquiry instruction to report issue, was completed in under 4 days.
