Brownfield Briefing - Remediation Innovation Awards 2005
30 September 2005, News release from Newzeye
The inaugural Brownfield Briefing Remediation Awards, sponsored by Osborne, were presented last night at a reception in London following the annual Contaminated Land and Brownfield Remediation Conference.
The awards aim to recognise best practice in remediation and use of remediation technology throughout the UK. The awards were divided into three categories of remediation techniques, assessing the best use of biological, chemical and combined treatment with a separate award for the most innovative method.
All entries were judged by an independent panel which included experts from both industry and academia.
The winners were:
Best use of Bio Systems and Most innovative remediation method
Parsons Brinckerhoff was awarded both Best use of Biological Systems and Most Innovative Remediation Method for its innovative in-situ solution - SEREBAR System - applied to an operational gas centre in Devon.
Gas sites are problematic, but operational ones especially so. The site required remediation due to threats to groundwater from pollutants, including cyanide, PAHs and organic compounds associated with town gas production. Parsons Brinckerhoff was the environmental consultant (through a Term Commission with SecondSite Property Holdings Ltd. for the remediation of the operation site. Significant industrial and government support for this project (£1.5 million - the largest award within the Bioremediation LINK Scheme) is providing a full-scale implementation of the technology.
Gordon Lethbridge, Chair of the technical committee as CL:AIRE and one of the judges commented on the scheme:
Best use of chemical systems
QDS Environmental Ltd won this section for its in-situ chemical oxidation treatment for groundwater remediation at a city centre site in Leicester. The site, formerly a textile works, was being redeveloped for residential end use and included a listed Victorian mill building. The principal contaminants present on the site were dissolved and absorbed phase chlorinated solvents (PCE, TCE, DCE, VC) within the River Terrace Gravels aquifer.
The client required a powerful and reliable remediation solution that would not disrupt the development activities and which could be completed within a six-week window. In-situ chemical oxidation was the only treatment technique capable of achieving the required rapid completion. This technique also avoided the need to install wells within the footprint of the listed building or to build remediation infrastructure into the development works.
Phil Crowcroft, Director of ERM and one of the judges said of QDS's nomination:
Best use of combined treatment systems
Komex won the combined category for a number of factors, including clear integration of different technologies, and detailed cost-benefit analyses on its remediation of the former gasworks in High Wycombe for site-owners SecondSite Property.
The site presented a number of challenging features, including: sensitive environmental setting near a public water supply well and river; location in the centre of a busy town; steep topography (10m elevation change across site) and relatively confined area (1.45ha); significant changes in geology across the site (gravel aquifer to the north and chalk outcrop to the south); and a wide variety of historical structures and contaminants. A number of physical constraints existed on the site, including site boundaries and the presence of a low permeability 'barrier' layer between the contaminated gravel aquifer and main chalk aquifer.
Phil Crowcroft commented on this entry with:
The runners up were:
1. Best use of bio systems
Runners up in this category were Environmental Science Group for its landfarming project (bioremediation through composting) to clean up diesel-contaminated lagoon sediments for the MoD at Horsea Island, Portsmouth; and WSP Remediation for its work on Persimmon Homes' Breme Park site in Bromsgrove, which included vacuum extraction and 'bioslurping' techniques to treat groundwater and ex-situ bioremediation to treat hydrocarbon-contaminated soils.
2. Best use of chemical systems
WSP Remediation - in partnership with Taylor Woodrow Developments - was again a runner up in this category, for its work to clean up chromium on the former AE Goetze Site in Salisbury by means of a chemical conversion process. The project is believed to be the UK's first large-scale chromium reduction project. Envirotreat was also a runner up for its rapid and cost-effective ex-situ application of Eclay ® technology to stabilise TPH-contaminated material at the fire-destroyed Bartoline Factory in Beverley.
3. Best use of combined treatment systems
Runners up in this category were Churngold Remediation, for its remediation of a hydrocarbon-contaminated industrial site at West Drayton using steam enhanced DPVE; and E&RS for its work to clean up a carbon disulphide-contaminated groundwater plume on Akzo Nobel's former chemicals manufacturing plant in Greater Manchester through soil stabilisation and removal and a 'funnel and gate' PRB system to prevent migration.
4. Most innovative remediation method
Churngold Remediation was highly commended in this category for its West Drayton steam enhanced DPVE project, which, in the first non-pilot application of this technology in the UK, removed TPH and almost all PAH compound to below laboratory detection limits within a 40-day treatment period. E&RS was also runner up for its application of a a 'funnel and gate' PRB system to treat carbon disulphide contamination at Akzo Nobel's former chemicals manufacturing plant in Manchester.
The Brownfield Briefing Remediation Innovation Awards will now be an annual event and the next Awards will be presented at a dinner to be held on 19 September, 2006. Calls for entries will be announced some time in May 2006.
