Dr. Eimear Cotter:

The pressures on water quality are different around the country depending on the location but, with regard to water bodies, the agriculture sector has the greatest impact on nutrient levels, nitrogen and phosphorous run-off. We see nitrogen entering our rivers, especially in the south, south east and east of the country, moving through them freely and draining into marine environments. We see impacts on water quality across the country. Phosphorous run-off into our rivers and other water bodies happens in more poorly drained soils. I am not sure if I am answering the Chairman's question.
