This is extremely alarming. What has led to this crisis, per Ms Larkin's submission, is the existence of deleterious materials. That has given rise to one of the biggest scandals in the history of this State. Deleterious materials were present and the levels were not in line with established European and Irish regulation. I am asking about the quarry that led to this audit. Has there been extensive geological examination? The second, related, question is what geological expertise does the NBCMSO have? What geologists does it lean on to assist with this?
