CL:AIRE is delighted to announce the publication of the “LNAPL illustrated handbook”, entitled Illustrated handbook of LNAPL transport and fate in the subsurface.
The LNAPL illustrated handbook presents best-practice guidance for the assessment and remediation of light non-aqueous phase liquids (LNAPLs) in the subsurface. LNAPLs notably include fuels and oils, for example petrol (gasoline), diesel and heating oils, and are amongst the most commonly encountered organic contaminants in the subsurface environment due to their ubiquitous use, accidental release and, perhaps, poor (historical) disposal. Central to the handbook and the management of risks posed is the development of conceptual models of LNAPL behaviour in common hydrogeological systems.
The LNAPL illustrated handbook provides a blend of technical detail and real world conceptualisation of the LNAPL problem and appropriate methods to investigate and manage it. The handbook also facilitates access to a wealth of detailed research, guidance and case study literature within the various topics covered. It will be useful to the practitioner and research communities, and also provide a valuable educational resource to others having a less direct interest or specialised knowledge.
The LNAPL illustrated handbook has been written by the following authors - Derek Tomlinson (Geosyntec Consultants), Steven Thornton (University of Sheffield), Alan Thomas (ERM), Stephen Leharne (University of Greenwich) and Gary Wealthall (Geosyntec Consultants) - and edited by Michael Rivett (University of Birmingham).
The production of the LNAPL illustrated handbook was funded by Shell Global Solutions (UK) and supported by the Environment Agency.
The LNAPL illustrated handbook can be downloaded for free at www.claire.co.uk/LNAPL (PDF 17MB)
The latest Land Forum notes of the meeting held on the 25th November 2014 have been uploaded onto the dedicated web page www.claire.co.uk/landforum. Also uploaded are two draft papers detailing the National Quality Mark Scheme (NQMS) and Suitably Qualified Person (SQP) Declaration that were discussed at the meeting. To access the notes of the meeting and the papers please follow the links.
The National Quality Mark Scheme is an ongoing Land Forum initiative and the Land Forum - professional standards sub-group has been actioned to scope up further the National Quality Mark and role of an SQP. The sub-group will be doing this before the next Land Forum meeting and further information will be made available as soon as possible. The next Land Forum meeting will be held at the end of January 2015.

Defra has published an erratum for the C4SL project and this can be seen on the SP1010 project page. On this occasion they have made the amendments to the project documentation as well as detailing them within the erratum.
Following three successful training courses on understanding the use of the C4SLs, CL:AIRE is looking to organise a further three events in London, Manchester and Birmingham. Dates will be announced in the New Year.
A public consultation has recently been announced by the Environment Agency (EA) on new and revised standard rules permits. Readers may be particularly interested in the changes being proposed for recovery permits and soil recycling activities including via mobile plant.
The EA is asking for views on new and revised rule sets and risk assessments, as summarised below:
The consultation closes on 20th March 2015. To access the consultation please follow the link:
The Coal Authority and Environment Agency are working together to clean up pollution from abandoned metal mines in England. They require assistance in identifying treatment technologies that are effective for metals such as cadmium, zinc, copper and lead, and ideally have low operating costs. The Coal Authority has just published an open tender to identify a number of different experts who will be able to provide treatment advice on a range of different metal mine water chemistries and flows.
If you would be interested in submitting a tender, please visit the Coal Authority’s eTender portal, and look at the ‘current opportunities & notices’ section. You will need to register first (free). The closing date for tender submissions is 28 January 2015.
The following Draft International Standards (DISs) have been issued for public comment:
Those shown in bold WILL be adopted as British Standards as they are direct replacements for ISO 10381 series standards that are normative in BS 10175.
The training course is based on Version 2 of the Definition of Waste: Development Industry Code of Practice (DoWCoP) and will explain in detail how the various scenarios for material reuse are dealt with, the operational boundaries and interaction with other industry initiatives. Upon completion of the course delegates will be confident to use, or work alongside the DoWCoP.
Venues to be advised.
The Environment Agency and CL:AIRE undertook research to provide an analysis of the Definition of Waste: Development Industry Code of Practice (DoW CoP) use in London and the South East. The project focused on the impact the use of the DoW CoP is having on materials reuse and sustainable remediation of brownfield land in London and the South East.
The objectives of the research were to show how the DoW CoP is contributing to:-
The project was split into two phases; the first phase consisted of an audit of 32 projects in London and the South East. The main aim of Phase 1 was to show that the DoW CoP is contributing to more land being reused.
Phase 1 was also used to:-
In the second phase, basic sustainability assessments were undertaken comparing material management using the DoW CoP with an alternative option (Dig & Dump). Three projects which were audited in the first phase were selected for the Phase 2 sustainability assessment. Each of these projects fell under a separate DoW CoP scenario (Site of Origin, Direct Transfer and Cluster).
