London 2012 Olympic Park Environmental Cleanup Uses Leading Bioremediation Technology ORC Advanced® to Treat Hydrocarbons and Expedite Construction
3 August 2012, News release from Regenesis Ltd
The £6.09 billion development of the 200 hectare (500 acre) London 2012 Olympic Games Park has been one of the largest regeneration projects in recent years.
Located in Stratford in East London, the site was formerly an industrial estate with uses including chemical, fertilizer, engineering works, landfills and depots leaving a legacy of soil and groundwater contamination.
The Olympic Delivery Authority (ODA) set strict deadlines for the Olympic facility construction projects. The development included the construction and refurbishment of 16 new major stadia and sports facilities. The subsurface foundations for the London Aquatic Centre (LAC) were to be completed by the 27th July 2009 (exactly three years before the London 2012 Olympic Games Opening Ceremony).
The London Aquatic Centre site was contaminated with LNAPL lubricating oil. The first stage of remediation began in November 2007 using dual phase vacuum extraction (DPVE) to remove the LNAPL, however due to the strict ODA deadlines and integration with construction programmes (starting in April 2008) prolonged use of DPVE would not have been practical to remediate the dissolved phase hydrocarbon plume. An in situ solution was the only viable option.
Enhanced bioremediation, a widely accpeted and understood natural cleanup process which utilises indigenous microbes to aerobically biodegrade petroleum hydrocarbons, was chosen as it could be easily facilitated using an injectable, Advanced Oxygen Release Compound (ORC Advanced®). ORC Advanced® accelerates enhanced aerobic bioremediation by releasing dissolved oxygen for periods up to 12 months on a single application.
Regenesis' patented Controlled-Release Technology (CRT) allows for an efficient, long-term release of oxygen providing the optimal conditions for sustained aerobic biodegradation, saving time and money by eliminating the need for multiple applications.
ORC Advanced® was applied at the London 2012 Olympic Games site using direct push injection. This meant that there was no need for well installation, no above-ground piping or mechanical equipment, and after application, no operational costs or further site disturbance.
Regenesis products are utilised every working day in the UK and they are widely accepted across the industry. Remedial objectives for the Olympic Games Aquatc Centre were satisfied and the construction-phase took place according to the ODA set deadlines and unhindered by ongoing remedial work.
Regenesis is proud to have supported environmental consultants, remediation contractors and regulators in successfully delivering the multi-billion pound, award winning, remediation for The London 2012 Olympic Games.
