Dr. Marie Archbold:

I will start by answering the Deputy's question about the model, and "model" is a loose term that is used when it is more of a process. Under the river basin management plan, there is a process called a characterisation risk assessment. The EPA undertakes that assessment. It involves using more than 140 datasets from all the people in the different organisations represented at this meeting and 30 or 40 other organisations that are involved in water management.
