Mr. Micheál O'Mahony:

There are shellfish waters that we classify, which have problematic microbiological results. Can we say to the Senator that they are because of incomplete treatment of human sewage in those areas?

No, we cannot. What I can do is think of examples where we had particularly poor results and saw dramatic and even exponential improvements following the installation of secondary and tertiary treatment in those areas. We definitely have concrete examples of those.
