The second local issue is that around the Vartry reservoir in Roundwood the level of lighting seems to be excessive at night, although it has been reduced. Why does there need to be that much light around the reservoir at night? There may be health and safety issues for staff who work there, but it seems to be excessive. There is an energy aspect and a light-pollution aspect and if it is not necessary, I ask that some intervention be made.

I will turn to water quality, especially as it relates to human health. What are the predominant organic loadings and their source in respect of the trihalomethanes that develop in drinking water supplies from chlorine treatment?
