CL:AIRE is pleased to announce the following Early Stage Researcher (ESR) or Experienced Researcher (ER) fellowship within the project ADVOCATE Initial Training Network.
The fellowship "Modelling the transport and natural attenuation of multiple contaminants in groundwater" will be carried out at the Université de Liège in Beligum from November 2013. It will be up to 12 months for ESR (PhD candidate level) and up to 6 to 8 months for ER (postdoc level).
For the ESR position the successful candidate will have a Masters degree in Engineering Geology, Geology or any related field, with an interest and skills in reactive transport modelling in groundwater. For the ER position, a PhD or 4 years equivalent full-time research experience in numerical reactive transport modelling of contaminants in the subsurface is also required.

CL:AIRE is pleased to announce that Case Study Bulletin 11 (CSB11) is now freely available to download from the Publications Library area of our website.
CSB11 - Remediation of Four Sites in Northwest England: A Successfully Completed Multi-Site, Multi-Consultant Cluster Project
This bulletin was written by WorleyParsons and This case study details the conceptualisation, development and successful completion of the UK's very first multiple site, multiple consultant, Cluster project. This project has allowed the remediation of four sites, two of which were heavily constrained, and has delivered significant efficiency, sustainability and cost savings.
The project was considered by the client, National Grid Property Holdings Ltd, regulators and all involved to have been very successful, completing on time and budget; 60% of all excavated material (70% of treatable material) was reused on the sites. This is despite being the first application of a Cluster of this complexity with the multi-site, multi-consultant contractual approach.

CL:AIRE would like to announce that the SNOWMAN funded IMaHg project results will be presented on the 29th November at the IMaHg final on-line workshop connecting national meeting rooms in Sweden, England, The Netherlands, Belgium and France. IMaHg is focused on enhancing knowledge in mercury fate and transport for improved management of Hg soil contamination. SNOWMAN is the European network for Sustainable Management of Soil and Groundwater (www.snowmannetwork.com).

CL:AIRE would like to thank all those who attended its annual conference last week; over 110 delegates joined us at the Geological Society. The first session on the SuRF-UK initiative focused on the development and use of the Tier 1 assessment along with case studies. The second session presented the uptake and use of the Definition of Waste Code of Practice. The plans for a third version were outlined and case studies were presented on complex, large sites and tools developed to help link sites together for excavated materials reuse.
A lively evening debate session was held to discuss the future of both initiatives followed by drinks and networking.
Feedback received from delegates was extremely positive and included the following comments -
"Highly impressed with the organisation/co-ordination and Burlington House was an excellent and very appropriate venue"
"I would definitely return, can't think how it could get better, well done!"
CL:AIRE is pleased to announce that a new technology demonstration project called “In situ chemical oxidation of carbon disulphide using activated persulphate” has been approved by the CL:AIRE Technology and Research Group as CL:AIRE TDP32.
This project was undertaken by ARCADIS using Klozur persulphate from FMC Environmental Solutions. It involved the research and development of a novel remedial approach using activated persulphate to destroy carbon disulphide (CS2) in situ.
Remediation of CS2 poses multiple technical difficulties due to the chemical properties of this contaminant. CS2 is a highly volatile and extremely flammable liquid with a wider explosive range in air than hydrogen. CS2 can exist in the environment as a dense non-aqueous phase liquid (DNAPL) which can form a dissolved phase plume. Prior to development of this technique there were no safe or effective in situ technologies available in the UK for remediation of this compound in soils and associated groundwater.
The objectives of the project were:
The project represents a world first application of in situ chemical oxidation of CS2 using persulphate.
Contaminant delineation and remedial progress monitoring was undertaken using an innovative adapted Membrane Interface Probe (MIP), which employed a Flame Photometric Detector (FPD) for increased sensitivity. This was the first demonstration of use of the FPD with the MIP.
An onsite mobile laboratory with a gas chromatograph was employed with CS2 analytical capabilities which allowed rapid turnaround sample analysis. A novel proprietary persulphate field test kit was developed, which was used to provide instant data on oxidant distribution for use as a line of evidence for the design of oxidant delivery.
Procedures were developed for in situ soil mixing of persulphate with CS2 impacted soils including vapour, dust, odour and temperature control and the creation of a controlled inert atmosphere in the soil mixing zone.
The use of an in situ approach led to a greatly reduced requirement for housing demolition. Combined with the associated reduction in lorry movements and the lack of large scale excavation equipment in use resulted in a significantly reduced impact on the local community (a key consideration given the sensitive residential location of the site).
The technology is applicable for a wide array of organic contaminants as persulphate can be activated to destroy multiple organic contaminants.
The TDP bulletin is now being prepared and will be available in early 2014.
The Environment Agency has released a 3rd editions of its guidance "Hazardous Waste: Interpretation of the definition and classification of hazardous waste." It provides technical guidance on the assessment and classification of hazardous waste.

CL:AIRE online training modules on In-situ bioremediation, Monitored Natural Attenuation and Options Appraisal have recently been endorsed by the Geological Society of London. CL:AIRE is pleased that these modules have gained recognition from such a leading institution.
CL:AIRE will be submitting more of its modules in due course and hope they will achieve equal success.
The Common Forum on Contaminated Land in the European Union (CF) and the Network for Industrially Contaminated Land in Europe (NICOLE) recently issued a 'Joint Position Statement on Sustainable Remediation of contaminated soil, sediment and groundwater'.
Agreeing on the necessity for protecting human populations and the environment against contaminated media and the mitigation of significant risks,the CF and NICOLE recognise that as a society, people need to be sure that money is well spent remediating sites, and that the benefits achieved by remediation outweigh the impacts. CF and NICOLE consider stakeholder engagement as crucial to ensure that a sustainability assessment minimises uncertainties in its consideration of project-specific issues and concerns, and allows stakeholders to provide their perspectives on the balance of potential impacts and benefits.
