§ Mr. Andrew F. Bennettasked the Secretary of State for Defence, since the Nugent committee report in 1971–1973, what further discussions have taken place about Gruinard Island, NG ref. 9494, with a view to ascertaining how far it is still contaminated with anthrax; and if he will estimate the cost and effectiveness of de-contamination.
§ Mr. PattieAs I told the House on 26 July 1982—[Vol. 28, c. 390]—the likely duration of contamination, methods of decontamination, their potential effectiveness and their cost remain under careful review. Field trials of a number of potential decontaminants took place on Gruinard Island last July and August. Preliminary results and laboratory tests have shown that decontamination should be possible, but further study, including the techniques to be used and of any possible ecological effects, is needed. Further field trials will be undertaken this year.
