Earlier this month we were awarded a contract to investigate the forecourt area at a motorway service area in southern England, for a major oil company, as part of a leasehold transition.
With data from over thirty boreholes and monitoring wells this was a relatively detailed investigation for forecourt investigation. However, our client understood that carrying our a comprehensive combined environmental and geotechnical ground investigation at an early stage invariable pays saves money in the long run.
We used our GeoProbe direct-push drilling system to construct boreholes, targeting key areas such as the below-ground fuel tanks, fuel lines and forecourt interceptor. We then analysed the soil and groundwater samples for our hydrocarbon suite at our own UKAS
accredited laboratory.
Our investigation report has provided our client with a detailed baseline study confirming ground quality and highlighting any areas of contamination at the time they took over mangement of the site.

Subadra Awarded Multi-site Remediation Portfolio
We have been awarded a major remediation portfolio by one of the UK’s biggest fuel retailers. The multi-site portfolio will see us working at a sites across the UK using a wide variety of both in situ and ex situ remediation techniques. We understand that a key reason for us winning this work was our ability to provide cost-effective turnkey solutions, integrating site investigation, laboratory testing, fate-transport modelling and remediation design and implimentation using solely in house resources.
Subadra Go Bananas
We certainly get to work at a wide variety of different sites, but a call from a major banana distributor was a first even for us. The underground pipework carrying fuel to supply their trucks had failed and required urgent replacement. At short notice we were on site replacing the corroded steel pipework with modern plastic equivalents. We sampled the soil around the failed pipework and our in-house laboratory was able to confirm within 24 hours that no significant ground contamination had occurred. Within 36 hours the fuel supply system was back in commission and the banana trucks had started rolling again.
Subadra Appointed to Advise Retail Motor Industry Federation
Subadra have been appointed by the Retail Motor Industry Federation (RMI) to provide specialist environmental advice to their members. The RMI represents the interests of petrol retailers and forecourt operators across the UK. They provide support on matters ranging from contaminated fuel problems to getting a better deal with your fuel supplier.
We join their technical support team in providing practical and sensible advise for all matters associated with fuel leaks, spills and ground contamination issues.
Whether you need guiding through the planning process during a site redevelopment or you suspect you may have had a fuel leak – we can help.
Please contact James Edley(Tel. 01296 739412 or email) for further information.
Subadra win multi-site forecourt investigation package
Subadra have recently been awarded a package of investigation works by one of the major oil companies. We were selected based upon our continued excellent working relationships with the end client and their project managers , continuing to provide a high quality service and as always being able to offer cost effective site investigation services.
Particular praise was made of the quality of our tender submission, highlighting key areas of excellence and capabilities which enabled the client to quickly and easily conclude that we were the service provider best suited to complete the works.
The works package includes investigating 12 retail filling sites using our GeoProbe direct-push drilling system. The majority of the chemical analysis will be completed by our UKAS accredited laboratory. The reporting deadlines for the package is six weeks from the point of instruction. Contact value: ~£55k+
There are always cost savings to be made when multi-site packages are being completed and we like to pass these savings onto the client. If you have a small network of filling station sites or are a ‘Top-50’ operator and need an environmental survey get in touch to discuss our highly competitive rates.
Foundations for Key City Data Centre
Whilst much of our work in carried out in the provinces we sometimes dabble with high finance in the City.
Subadra played a key role in the development of an £80 million multi-storey data centre facility in London’s docklands area. We were brought in at the inception of the project to carry out a geotechnical and environmental investigation to determine ground conditions.
Our investigation comprised a network of boreholes across the development area that were used to collect soil samples for analysis and groundwater and hazardous gas monitoring points.
The site was especially tricky geotechnically, comprising areas of in-filled docks, some highly contaminated and others containing very soft silts and clays.
We used the data to assist with foundation design and the classification of waste soil.

Remediation Following Filling Station Fuel Leak
It’s not often that we post anything about our remediation projects. Mostly this is because they are often covered by confidentiality agreements and sometimes because they are too complex to be neatly summarised in a few paragraphs. So it’s nice to be able to report the successful completion of a remediation project at a filling station site in London. Over the Christmas holiday one of the tanks at the site was found to be leaking. The site is located in a very sensitive area environmentally: in a source protection zone and directly above London’s chalk aquifer. Despite the holiday festivities, we were able to mobilise a drilling team to the site. Our investigation quickly delineated the contaminated soil, with our in-house laboratory reporting their analysis results within 48 hours of sampling. This in turn meant we were able to excavate and treat the soil before the leaked fuel had a chance to penetrate to the underlying aquifer, saving our client from having to carry out a costly and time consuming groundwater treatment.
Contract Value £10-20k
From Scrapyard to Parkland
Subadra have completed the successful transformation of a former scrap yard site into a public open space – on time and under budget.
Subadra, acting as Principal Contractor, have recently completed the investigation, remediation and landscaping of a 0.3ha former scrap yard site in Harmondsworth following an eight week program of works. Following detailed site characterisation works, we devised a remedial strategy comprising the targeted excavation of contaminated soils using GPS surveying equipment. Contamination issues included soils impacted with lead, hydrocarbons and solvents and additional impact of underlying groundwater. We pre-treated excavated soils on site, with over 100tonnes of material reclaimed for re-use on site.
Over 500tonnes of soil required offsite disposal to recycling facilities and an additional 30tonnes of plastic waste and 8tonnes of metal were recovered. Groundwater was treated with in-situ oxygen release compounds. Following remedial works we have completed detailed landscaping of the site, importing over 800tonnes of top soil and foundation materials, meeting the Client’s requirements to return the site to public open space. The site will shortly form part of the larger Harmondsworth Moor parkland complex.
