CL:AIRE bulletins - 50% discount for CL:AIRE members

If you would like to publish a CL:AIRE Bulletin, we are offering a 50% discount in the bulletin fee to CL:AIRE members.  CL:AIRE publishes a number of different types of bulletin (Case Study, Technical, Research, Site, Guidance etc) which can be used to inform the industry about your project, technology or research.  All bulletins are reviewed by CL:AIRE's Technology and Research Group to make sure they are of the highest quality.

If you are interested in this opportunity, please email This email address is being protected from spambots. You need JavaScript enabled to view it.

For a 4-page CL:AIRE bulletin we typically receive a word count of 3000-4000 words, with 6 or 8 figures, diagrams, photos or tables etc.   We prefer you to provide the document in Word and any illustrative material as separate electronic files (e.g. jpg), rather than embedding them in Word.  Also, please remember to provide some appropriate contact details at the end.

Style guide
As a guide to content and style of writing, our audience is very varied (local authority, site owner, consultant, contractor, student, general public etc), and so we like to ease the reader into the subject matter by providing a general introduction and setting the scene.  This does not have to be in great detail and you might find previous bulletins a useful guide (see the Resources/Publications Library area of the CL:AIRE website

Review process
Once we have received your text (in Word), we will send it to the CL:AIRE independent review panel, the Technology and Research Group to review. Once you have addressed any comments, we will put it into a desktop publishing package, and send it back to you for review as a pdf. Once published, your bulletin can be considered a peer reviewed document.

We charge £3000 for a pdf bulletin, which will be promoted widely via our website.  The 50% discount only applies to the 4 page bulletins described above.

Initial Observations of Contaminated Land Expert Panel

From the cases reviewed to date, the contaminated land expert panel has prepared a short document on their initial observations to help local authorities in their determinations of sites. The information is presented under the four key areas in line with what is required to be included within a risk summary as per section 3.35 of the EPA 1990: Part 2A Contaminated Land Statutory Guidance April 2012.  The headings include: understanding the risks, understanding the uncertainties, putting the risks in context and possible remediation that could occur on the site.

Defra Contaminated Land Survey Research Project

The Department of Environment, Food and Rural Affairs (Defra), the Welsh Government, the Environment Agency and Natural Resources Wales ask for your participation in an important survey on the impact of the revised Part 2A Statutory guidance and supporting research projects, publications and other initiatives.

The aim of the survey is two-fold:

1.    Assessing the level of understanding across the sector of the key principles that were introduced under the revised Statutory Guidance, implemented by Defra and the Welsh Government in April 2012.

2.    Gathering Local Authority and other stakeholder views on the usefulness of the revised Part 2A Statutory Guidance for the determination of contaminated land, as well as its impacts on the land contamination sector in England and Wales.

Please click here>>>

The survey is open for a five-week period (from Monday 27 January until Friday 28 February 2014, midnight)  and is being administered by Cranfield University on behalf of the English and Welsh government departments.

If you have any questions about the survey, please contact This email address is being protected from spambots. You need JavaScript enabled to view it.
