New C4SL Workshops Announced

CL:AIRE is delighted to announce it is running three workshops in association with the project consortium partners that developed the Category 4 Screening Levels (C4SLs) on the following dates:

London:  September 23rd 2014
Manchester: October 14th 2014
Birmingham: November 26th 2014 (In association with EP UK West Midlands Region)

For further details and to download the PDF flyer click here>>>


£150 + VAT (CL:AIRE members discounts apply)


The aim of the workshop is to:

- Explain the drivers and purpose of the C4SLs
- Understand  the methodology and approach that was taken to derive the C4SLs for all six substances
- Better understand how C4SLs should be used
- Learn what should be considered in the derivation of other C4SLs

Each workshop will have two presenters (a toxicologist and exposure modeller) to enable participants to have the opportunity to learn both key aspects.  Numbers are limited to 40 people so book your place to avoid disappointment.

Who Should Attend?

The workshop is aimed at practitioners in the public and private sector who work with land affected by contamination.


Registration will be 9.30am with teas and coffee on arrival.  The workshop will start at 10am and finish at 4pm with a buffet lunch and drinks provided.

Government initiatives to help build more new homes on brownfield land

Thousands of new homes will be built on unused and previously-developed land under the government’s plans to make it easier to build on brownfield sites suitable for housing.

Ministers are clear of the need to make the best possible use of brownfield land in a way that keeps strong safeguards in place that protect our valued countryside.

Councils will play a critical role in bringing forward brownfield land and will be asked to put in place local development orders which can provide sites with outline planning permission to speed up the building of new homes.

Environment Agency Website

You are probably aware by now of the closure of the Environment Agency’s old web site and the move to .GOV.UK. This is an ongoing process and as part of the migration detailed reviews are being undertaken by Defra. In the interim you are still able to access guidance that was held on the old site. A Land Contamination Technical Guidance page has been published on .GOV.UK.

This page features many of the more popular Environment Agency land contamination documents, though others are on GOV.UK and the old archived site (a link to which is also provided on the page).

Site Search for CL:AIRE RP25 Project

The Cleaning Land for Wealth (CL4W) project (approved as CL:AIRE RP25) is seeking suitable sites that have high concentrations of nickel, arsenic and Platinum Group Metals (PGMs) in soil where samples can be collected for lab trials. The site should have suitable ground conditions (no obstructions, no stiff clays, range of soils welcome) and contamination levels for nickel and arsenic ideally (but not necessarily) will be in the range of 100-5000 mg/kg, and for PGM ideally high but any level will be considered. Sites proposed should be in the UK and available for access from now until November 2015.

If you have a suitable site please email This email address is being protected from spambots. You need JavaScript enabled to view it. .

Cleaning Land for Wealth (CL4W) is an EPSRC funded collaborative project joining 5 leading UK Universities. The project examines the potential to recover valuable metals and energy from plants used for phytoremediation when cleaning land contaminated with elemental contaminants, in particularly nickel, arsenic and PGMs.  For further information click here>>>
