Land Contamination 2016

CL:AIRE is delighted to be partnering with The Geological Society in holding a one day conference in Cardiff, Wales on Monday 21 March 2016 focussing on land contamination.

As part of the Geological Society’s Year of Water this one day meeting will discuss the latest policy and how new technology can benefit the management, regulation, assessment and characterisation of land affected by contamination.

The meeting will comprise a series of 20 minute presentations and abstracts (<400 words) are invited from those wishing to present.

The following topics are of particular interest:

  • Latest policy on dealing with land contamination and putting this into practice
  • Reducing the costs of dealing with land contamination (investigation and remediation)
  • Remote sensing in land contamination
  • Rapid measurement techniques during site investigation
  • New and innovative remediation technologies
  • Sustainable remediation

Please submit abstracts or raise any queries to Gareth Farr, Chair of the Geological Society’s Southern Wales Regional Group at: This email address is being protected from spambots. You need JavaScript enabled to view it.   or 02920 521962.

The deadline for submissions is 27 November 2015.

New Stabilisation/Solidification Manual of Practice

A new publication is available which presents the state of the art on the application of stabilisation/solidification (S/S) in the field.

S/S is a remedial technology that has attracted widespread use around the world. S/S employs readily available cement-based binders that can be formulated into a targeted ‘system’ that cements soil or waste into a hardened engineering material. The application of S/S results in the physical and chemical stabilisation of contaminated material over the long term, enabling disposal or re-use on- or off-site.

This "Manual of Practice" has been designed as a practical reference for regulators, site owners, engineering firms, and others involved in selecting, designing, bidding, and providing oversight for the remediation of sites using S/S. It provides guidance on applicable contaminants, site characteristics, project planning, equipment capabilities, production rates, performance specifications and the quality assurance of S/S treated materials.


Open call for papers on Global trends in sustainable and green remediation - Special Issue

A Special Issue of the Journal of Environmental Management is being prepared on "Global trends in sustainable and green remediation" with an open call for contributions closing 30th November 2015.


Latest Land Forum Notes Published

The latest Land Forum minutes from the meeting held on 30 June 2015 have now been uploaded onto the dedicated webpage

Update (version 1.07) to CLEA software

An update (version 1.07) to the contaminated land exposure assessment (CLEA) software has been published at

The update includes the library data sets from the Defra research project SP1010 (Development of Category 4 Screening Levels for assessment of land affected by contamination).

The handbook referring to version 1.05 is still valid as the functionality has not changed significantly. The revised software (version 1.07) has been published under the Government Open Licence which should be referred to for terms of use.

CL:AIRE supporting the 4th International Sustainable Remediation Conference SustRem 2016

CL:AIRE is delighted to be supporting the 4th International Sustainable Remediation Conference (SustRem), which is being held on 26-28 April 2016 in Montreal, Canada.

The call for abstracts is now open and closes on 14 October 2015.

The conference aims to stimulate international exchange by providing a venue for public, private, and academic sectors to share experiences and perspectives on how contaminated sites can be remediated with a smaller overall footprint and more positive outcomes, and how their reuse can contribute to a more sustainable land development.

EA withdraws the nickel Soil Guideline Value reports

The Environment Agency (EA) has decided to withdraw the Soil Guideline Value (SGV) for nickel and the supporting reports following discussions with Public Health England (PHE) about new information. The SGV report, the toxicity (TOX) report, and the supporting information document for nickel will remain available for historical reference on the EA archives.

The SGV for nickel was published in 2009.  In February 2015, the European Food Safety Authority (EFSA) published their scientific opinion on the public health risk from the presence of nickel in food and drinking water.  The full report is available here:

EFSA recommend an oral TDI for nickel that is considerably lower than the oral HCV used in the derivation of the SGV.  The EA is withdrawing their reports in light of this new expert opinion.  The EA will not be updating them as it no longer undertakes work to derive new SGV or TOX reports, but it will continue to recommend that relevant public health bodies are consulted on any new industry-led guideline value projects.

Revised code of practice for ground investigations - BS 5930

The 2015 revision of BS5930 has been completed and is now available from the BSI website

BS 5930:2015 deals with the investigation of sites in order to assess their suitability for construction and to identify the characteristics of a site that affect the design and construction of the project. It also considers related issues including the environment and the security of adjacent land and property. 


SuRF International and Partners recent notes of meeting are published

The chairs of the SuRF International groups and associated  partners met on 2 July 2015.  The notes of the meeting have now been published on the dedicated website and can be downloaded directly here (pdf 241KB).

ISO publishes Committee Draft ISO 8400-104 Soil quality - Sampling Strategies

A second Committee Draft of ISO 18400-104 which provides guidance on investigation and sampling strategies has been published for comment. This is an important standard because it will in due course replace (BS) ISO 10381-2 and become “normative” in BS 10175, i.e. essential for its proper application.

The present draft is a much revised version of the earlier draft issued towards the end of last year.

The main text is comparatively short but there are lengthy informative annexes. Any comments would be very welcome even if they refer to a single paragraph or short section of the draft.

The closing date for comments to be received by BSI is 1 September 2015

Copies of the draft standards together with a comment template can be obtained from the Secretary of BSI Committee EH4 – Soil quality This email address is being protected from spambots.

CL:AIRE Register of Materials - New Sites added

We have recently added the following new sites to our Register of Materials which supports the use of the CL:AIRE Definition of Waste: Development Industry Code of Practice.

CL:AIRE keeps a Register of Materials and services which might fall within the DoWCoP.

It helps to link material holders with projects requiring materials.

Organisations involved in the management of development sites are urged to register key information to be held confidentially and presented by CL:AIRE.

CL:AIRE will act to make the introductions and offer any further services as required in order to ensure successful partnerships are achieved.

For any technical queries relating to the Definition of Waste: Code of Practice please contact Nicholas Willenbrock at This email address is being protected from spambots. You need JavaScript enabled to view it.

Land Forum produce a briefing note on the proposed National Quality Mark Scheme

As a result of the consultation carried out on the proposed National Quality Mark Scheme for Land Affected by Contamination (NQMS), it has come to the attention of the Land Forum that there is some misunderstanding about the proposed scheme particularly amongst local authority contaminated land officers and environmental health officers.

Local authority representatives who sit on the Land Forum have therefore produced a short briefing note explaining the main aims of the proposed scheme, its key features and has addressed some of the common concerns raised by local authority officers.
