New CL:AIRE TDP25 bulletin and decision support tool available

CL:AIRE is pleased to announce the publication of Technology Demonstration Project Bulletin TDP25 and an In Situ Chemical Oxidation (ISCO) decision support tool, which are now available to download.

TDP25 is titled, "Decision support tool for innovative in situ multi-contaminant groundwater remediation" and describes the development of a decision support framework to assist practitioners and other stakeholders on the decision of whether to use ISCO for the remediation of contaminated groundwater and, if deemed appropriate, guidance on the selection of chemical oxidants and their application in the subsurface.

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.
