Anyone who has not seen the testimony of Andreas Leemann to the committee can watch it. Likewise, the testimony of other experts from Canada, Norway and the UK is available. I understand they will be assisting the GSI. Everybody accepts now the resource provided by international experts and people who we want to help us in Ireland. Dr. Leemann has said that the tests he has carried out demonstrates seven to ten times the permissible level of sulphur under EN 12/620. I am sure Mr. McGrath agrees that is astonishing, even though the regulation has been in place since 2002 and these tests were on blocks that were manufactured after 2002.

In terms of quarries and manufacturers across the entire State that manufacture concrete products, can Mr. McGrath satisfy the public that the failings that led to this scandal - the faulty quarries and products - are a thing of the past and that there is extensive geological oversight being carried out to ensure this will not happen again? Do we need more people and more work in this area?
