Dr. Michelle Minihan:

It is a mixture of both. In order for a supply to be assessed to go on the remedial action list, RAL, we will assess all the exceedances that have been reported to us. Some of those are at the plant itself. We will have non-compliance at the plant and in some cases we will have non-compliance at people's taps. That is how the sampling programme is operated. There is ongoing monitoring of how the plant is performing to ensure it is meeting the regulatory standards. In the directive, however, the point of compliance is the consumer's taps. If you are getting it in the plant, inevitably you will get it in consumer's taps.
