From the East Midlands District Council website (November 03):
“A number of people have asked about the decontamination that will take place at the affected area of woodland.
Dstl (Ministry of Defence’s Defence and Scientific Testing Laboratory (DSTL) in Porton Down,) will do an initial sampling of the area to determine the extent of the contamination. They will then remove any contaminated soil. Any artefacts or munitions related to chemical weapons will also be removed. These items and the soil will be taken to Dstl at Porton Down where they will be incinerated.
Experts will also undertake some sampling of soil, particularly on the walkways, after the clearing has been completed to ensure the process has been successful. Dstl are the only licensed facility in the country who are able to safely dispose of chemical weapons. Dstl will not be removing any trees so there will be no change to the landscape of the woods.”
