Mr. Barry Fox:

From IFI's perspective, approximately 25% of our pollutions would be from an unknown source. That is because we are investigating live discharges and trying to understand something that may have happened 12, 24 or sometimes ten days before we get notified. Some of these rivers are so remote the fish kills or the impacts are not observed for a period of time. The officers who are on the ground doing this job do it professionally, diligently and they are authorised officers of the State. We are averaging 100 to 120 prosecutions a year. About 50% of those of are environmental prosecutions, but it is a reactive type of role. It is not something where we are sitting waiting for something to happen, as such.
