The AGS Contaminated Land Working Group, led by Vivien Dent (RSK) met on 11th October in London for their final meeting of the year. The group are currently focusing their efforts on three primary issues;

WASTE CLASSIFICATION IN SOILS – A PRACTITIONER’S GUIDE
The Group feel there is uncertainty as to how to assess soils from construction sites. By producing the AGS stance on waste classification of soils, a unified approach across the industry can be adopted.

The Working Group have created an initial draft document which is currently being circulated for comment.

POSSIBLE UPDATES TO THE AGS COVER SYSTEM DOCUMENT
As the AGS/BRE/NHBC cover system document is over 13 years old, it is no longer used as much as it was. The Contaminated Land Working Group therefore feel that updates are required to bring the cover system up to date with current practices.

After reviewing the results of a questionnaire which was issued to Local Authorities, the Working Group have decided to compile a guidance note with updates, to make the document relevant once again. This will be a major focus for the Group in 2018.

GUIDELINES TO GOOD PRACTICE IN GEOENVIRONMENTAL GROUND INVESTIGATION
Where the standard of ground investigation varies greatly, the AGS would like to promote best practice and raise the standard of ground investigation where needed.

The Contaminated Land Working Group have therefore drafted a document to allow members to see where improvements can be made in relation to their own work. This draft document will be ready for circulation in due course.
