Soil Groundwater Remediation Solutions Waste Management Disposal Environmental Support Services

Negotiation of difficult contract exit from a £300k groundwater remediation scheme in SE London for a confidential client renegotiating remediation target levels with the local authority regulator and Environment Agency whilst keeping the project within budget.

Railway Sidings Contract for national civil engineering contractor, London. The land was a historic land raised landfill that required removal ahead of the construction of the new railway infrastructure. The main contractor believed the work required was a straightforward dig and dump. We were able to explain that the former landfilled waste material on the site could, in fact, be processed and the materials segregated for recycling and reuse which ultimately saved the client in excess of £1M.

Soil and Groundwater Remediation Solutions, Waste Management & Disposal and Environmental Support Services

Excavation and disposal of asbestos impacted and potentially impacted soils from raised bed planters and two identified ‘hotspot’ areas within a Primary School ‘Green Space’ in North London. Over three days an excavation and disposal strategy was implemented for the safe removal of asbestos impacted and potentially impacted soils. The soils were identified as having some very minor impact with asbestos due to sources unknown. The excavated material, however, still needed handling by appropriately trained and ‘asbestos aware’ operatives. The works included:

  • The erection of sheeted fencing to segregate the public from the working areas and creation of a segregated soil stockpile enclosure.
  • The manual excavation and safe movement and removal of the asbestos impacted soils to the stockpile area prior to removal.
  • All personnel wore task appropriate PPE (rubber boots, rubber gloves, disposable overalls and disposable type respirators).
  • The covered stockpiled soil was removed by an eight-wheeled grab lorry suitably controlled by a dedicated Banksman from within the temporary stockpile enclosure each day.
  • The site was tidied and made good prior to demobilising from site.

Soil & Groundwater Remediation Solutions, Waste Management & Disposal and Environmental Support Services

Remediation of both soil and groundwater on a physically constrained site in Yorkshire which also needed to address the H&S challenges of being part of two live working engineering and manufacturing sites. The site’s most recent use had been an engineering ‘works’. The areas of soil impacted by the storage and handling of oils, solvents and diesel fuel formed the focus of the Remediation Works. The site had been contaminated through a series of leaks and spills principally around the storage tanks. The remediation strategy undertaken at the site comprised:

  • Removal of oil and impacted water from within the underground sump/ tank (associated with the Hammer Test Laboratory) and decommissioning of the tanks.
  • Removal of the perched groundwater associated with the underground sump/ tank;
  • Ex-situ bioremediation of the impacted soils associated with the Hammer Test Laboratory, waste storage area, former AST location and impacted soils associated with the underground sump/ tank
  • Chemical validation sampling of the bioremediated soils;
  • Re-use of the treated excavated soils in order to make good the one large excavation left open on site during the work and return the site to original levels.

Pioneering...

Ex-situ bioremediation of hydrocarbon contaminated soils at the former Carcroft Colliery in Barnsley as part of the coalfields regeneration programme for Yorkshire Forward. Local concern centred around the potential of the micro-organisms being used to degrade the contaminants in the soil such that our MD, Paul Garrett, provided an interview to BBC local radio and the local Star newspaper to explain there was no danger from so called ’superbugs’. The use of bioremediation has come a long way from those early pioneering days!

  • Removal of the impacted perched groundwater associated with the former workshop area;
  • Ex-situ bioremediation of the impacted soils associated with the colliery, waste storage area and the former workshop area
  • Chemical validation sampling of the bioremediated soils;
  • Re-use of the treated excavated soils in order to make good the one large excavation left open on site during the work and return the site to original levels.

Soil Groundwater Remediation Solutions Waste Management Disposal Environmental Support Services

Asbestos in Soil Remediation via hand picking and off-site disposal, managed and arranged by us and on site burial by others as part of the groundworks ahead of site reprofiling and the construction of over 75(No.) new homes. The works included scrub vegetation clearance by others, under our watching brief, to expose the surface soils known to be impacted with asbestos containing materials.  A number of fly-tipped stockpiles and ‘hotspot’ areas had been highlighted across the site by the client’s geo-environmental consultant and were individually targeted for hand picking. Two large areas of the site were stripped of 200mm of topsoil for processing by being laid out in the prepared treatment area to be hand-picked of the visible asbestos containing materials (ACMs), before being collected and transferred to the designated stockpile areas for either subsequent reuse, subject to confirmatory testing, or off-site disposal.

Impacted made ground material was inspected by a competent person for evidence of significant visible asbestos contamination which dictated the effectiveness of hand-picking and consignment for disposal accordingly. All material arising from made ground was stockpiled separately from uncontaminated and natural sources and all other arisings, due to the potential for cross contamination. All ACM was double bagged and temporarily kept in a locked skip prior to appropriate consignment and disposal. Some soils required direct disposal to landfill as ‘Hazardous Waste’ as hand-picking be deemed unfeasible. All double bagged asbestos waste materials were also disposed of as ‘Hazardous’ waste. Post remediation validation testing and inspection works were undertaken to prove that the works had been satisfactorily completed in accordance with the approved RMS.

Rapid Solutions for Modern Deadlines...

Remediation of an airport refuelling area ahead of the construction of a new rail interchange station. Historic contamination from the storage and handling of aviation fuel had left a legacy of hydrocarbon contamination within the shallow soils as well as free floating on the groundwater. A dual phase groundwater pump & treat system was designed, installed, maintained and operated to enable the main civils works to commence on time. In excess of 15,000 litres of free product was recovered during the 18 month operational period.
